Mailchimp vs Aweber (2019) - Comparison Review

Mailchimp vs Aweber comparison (image of an envelope showing both products' logos).

In this Mailchimp vs Aweber comparison review, we’re going to look at two of the best-known e-marketing solutions currently available and see which one is the best fit for your business.

Read on to get a full overview of both Mailchimp and Aweber’s feature set and why you might decide to use one of these tools over the other.

Let's start off by taking a look at the main things that Aweber and Mailchimp let you do.

What do Aweber and Mailchimp actually do?

Aweber and Mailchimp are tools that allow you to:

  • import and host a mailing list and capture data onto it using sign-up forms

  • create e-newsletters (both HTML and plain text) which can be sent to your subscribers

  • automate your messaging to subscribers via use of email autoresponders (see below for more information)

  • review statistics related to your email marketing campaigns – open rate, click through, forwards etc.

What are autoresponders?

Before progressing with this comparison review, it’s worth zooming in on something very important offered by both Mailchimp and Aweber: autoresponders. What are they?

Autoresponders are e-newsletters that are sent to your mailing list subscribers at pre-defined intervals – for example, you can set them up so that straight after somebody signs up to your list, they receive a welcome or ‘onboarding’ message from your business; a week later they could receive a promo code for specific products; two weeks later they could receive an encouragement to follow you on social media. And so on!

The idea behind autoresponders is that much of your email marketing gets automated – it’s a sort of ‘set and forget’ scenario that saves you the bother sending out e-newsletters manually (although you can still of course do this as and when required).

Regardless of whether you plump for Aweber or Mailchimp, it’s well worth investing some time in understanding autoresponders and using them effectively.

We’ll dig into autoresponder features a bit more comprehensively below. But before we do that, let’s take a look at pricing.


Aweber pricing

Pricing options in Aweber are fairly straightforward - there are 5 plans available. All have the same features, with the number of subscribers on your mailing list determining the cost.

The prices of these plans are as follows:

  • Hosting and emailing a list containing up to 500 subscribers: $19 per month

  • 501 to 2,500 subscribers: $29 per month

  • 2,501 to 5,000 subscribers: $49 per month

  • 5,001 to 10,000 subscribers: $69 per month

  • 10,001 to 25,000 subscribers: $149 per month

If your list contains over 25,000 subscribers, you will need to call Aweber for a quotation.

Mailchimp pricing

With Mailchimp, things are a little bit more complicated - there are three tiers of plan available, each with multiple pricing sub-tiers, which all depend on list size:

  • "Free”

  • "Grow"

  • "Pro"

Some of the key differences between the Mailchimp tiers involve

  • subscriber count — the free plan limits the number of subscribers to 2000

  • send limits — you can only send up to 12,000 emails per month on the free plan

  • support — you can only avail of this on paid plans

  • advanced segmentation — this is only available on the 'Pro Marketer' plan

  • reporting — the most advanced reporting features are only available on the 'Pro Marketer' plan

  • advanced multivariate testing — this is not available on the "Starting Up" or "Growing Business" but available on "Pro Marketer".

Free plans / trials

The Mailchimp ‘Free’ plan is arguably the strongest reason why you might want to choose Mailchimp as an email marketing solution.

Although this plan limits the number of subscribers you can send e-newsletters to 2,000 records, and the total number of sendable emails per month to 12,000, many of the other features you'll find in Mailchimp are fully present in this plan — and, as the name suggests, for free.

Accordingly, it's a good option for any business starting their list entirely from scratch, so long as support is not an issue (you won't get any on the free plan).

Aweber doesn't offer a free plan, but does allow you to try out the product for 30 days free of charge - you can sign up for the free Aweber trial here.

On the plus side, the Aweber free trial is fully functional; this will help you get a good sense of the product. On the down side, to access the free trial you have to enter your credit card details first. This contrasts negatively with Mailchimp (and indeed similar free trials offered by competing products such as Getresponse).

I suspect that the Mailchimp plan which is most relevant to readers comparing Aweber to Mailchimp would be the ‘Grow’ plan — this allows you to make use of most of the main features of Mailchimp, but withou.

Like Aweber, how much a plan costs depends on your list size, but unlike Aweber the pricing bands are much narrower, i.e.,

  • 0 to 500 subscribers: $10 per month

  • 501 to 1000 subscribers: $15 per month

  • 1001 to 1500 subscribers: $20 per month

...and so on, with the pricing bands becoming even narrower for list sizes over 2,500 records (where going up 100 records increases the price by $5 until you hit 2,700 records).

It’s all a bit confusing to be honest - but generally speaking, Mailchimp and Aweber are fairly similarly priced (up to 25k records at least), with Mailchimp definitely being cheaper for users with databases containing less than 1,501 records.

Pay as you go

An interesting option for users who mail their databases relatively infrequently is Mailchimp's 'Pay as You Go' plan, where you pay a set fee per email sent.

This varies according to the size of your mailouts - for example, if you send an e-newsletter to 1,000 recipients the price per email is 0.03c; at the other end of the spectrum if you email 50,000 the cost per email drops to 0.01c.

The pay-as-you-go payment model won't be for everyone, but it's potentially useful for users who are not interested in making use of autoresponders and only wish to send ad hoc, one-off blasts.

Finally, there’s the Mailchimp ‘Pro’ plan to consider. This plan is considerably more expensive than anything Aweber (and indeed competing products like Getresponse, Campaign Monitor and Mad Mimi) have to offer: on this plan, on top of the standard ‘Grow’ costs referred to above, you have to pay $199 per month.

For this, you get better segmentation, more split testing options (more on these below), access to additional API related functionality and other advanced features.

But as ever, price is not the only thing to bear in mind. Let’s look at some features.

Autoresponders and marketing automation in Mailchimp and Aweber

Both Mailchimp and Aweber allow you to create simple ‘time-based’ autoresponders - a series of emails based on time intervals (as discussed above).

I’d argue that for this kind of autoresponder, Aweber makes things a bit easier — setting up automation in Mailchimp can a bit fiddly whereas Aweber’s ‘Campaigns’ tool, which is used to create your autoresponder workflow, is very easy to use.

However, to properly compare Mailchimp and Aweber's autoresponder functionality, we need to look beyond traditional 'drip' style autoresponders and look more closely at the idea of marketing automation, something which has been introduced into many email marketing solutions over the past couple of years.

Marketing automation works in a similar way to autoresponders, in that emails are automatically sent to a mailing list according to a predefined sequence. But instead of time intervals, user behaviour is used to determine what should emails should be sent next — opens, clicks, goal completions, purchases, abandoned carts and more can all be used to trigger the next e-newsletter. 

As things stand, Mailchimp offers significantly more functionality when it comes to marketing automation: you can choose from a wide range of pre-defined workflows — ‘e-commerce’, ‘education’, ‘non-profit’ amongst others - or create your own using goals you define yourself. 

A simple example of a Mailchimp goal completion might be a purchase: you can add a Mailchimp script to a post-purchase page on your site, meaning that if a user arrives on that page after clicking on a link in one of your e-newsletters, Mailchimp is notified and the user is automatically sent a specific follow up communication.

Mailchimp marketing automation

Mailchimp marketing automation

Aweber's marketing automation is currently a bit more on the basic side — you can only use tags and clicks to create automated user journeys. That said, from chatting to Aweber's marketing team I know that they are working hard to add more functionality in this area.

As an aside, both products lag a bit behind their rival Getresponse in the marketing automation stakes (esepcially Aweber). This is because Getresponse now bundles CRM and webinar functionality into its plans, and you can integrate marketing automation with both.


Both Aweber and Mailchimp offer a wide range of e-newsletter templates, which are designed to suit many different applications and organisation types - e-commerce, events, sports, education and so on. Aweber offers far more templates than Mailchimp: around 700 to around 80 respectively.

With both systems you can tweak the templates extensively, and indeed code your own, so users of both platforms should be able to settle on a template which works for their business without too much difficulty.

The other good news about both products is that all the email templates provided are responsive, meaning that they will automatically resize themselves to suit the device your e-newsletter is being viewed on.

Mailchimp makes it easier, however, to preview the mobile version of your e-newsletter - there's a preview option you can use as you build it. By contrast, with Aweber, you'll have to send yourself a test email and open it on a smartphone to see what your e-newsletter looks like on a mobile device.

Mailchimp has a bit of an edge over Aweber when it comes to fonts — you can use web fonts in your templates (albeit a small selection), which can improve the look and feel of them considerably. Aweber, by contrast, limits font usage to 'web safe' ones: the boring but admittedly reliable Arial, Times New Roman, Trebuchet, Georgia etc.

However, the web fonts that you can use in Mailchimp are exceptionally dull — so dull in fact that you might be better off using the web safe ones, because they'll load more reliably and your e-newsletters will appear more consistently across email clients / devices. I love web fonts, but the Mailchimp offering on this front is so boring that there is currently little point to using them.

The Aweber and Mailchimp interfaces

When it comes to interfaces, Aweber and Mailchimp take quite different approaches.

Aweber’s interface is quite traditional in nature - when you log in you encounter a horizontal primary navigation containing key options such as ‘messages’, ‘subscribers’ and ‘reports’; hovering over menu items reveals sub-menus that let you ‘get at’ important secondary options (for example, email templates, import options and statistics).

Mailchimp on the other hand offers a very minimal interface — there is a smaller primary navigation to contend with, and no drop down menus are involved.

Whilst this makes for an initially 'cleaner' user experience, it also means that you have to click through to a second screen and then locate the option you’re looking for from another set of options (which are presented in the main page copy).

So despite the fact that the Mailchimp interface is undoubtedly easier on the eye, I find that actually locating key functionality with it is harder to do.

With Aweber, all the important options are easily located from the moment you log in — but with Mailchimp there is quite a bit more clicking around the place to do.

Editing e-newsletters

Both Aweber and Mailchimp take a ‘drag and drop’ approach to editing e-newsletters. You can add, move and edit elements such as text, images, logos and so on easily with both products.

One aspect of Aweber’s builder which I prefer over Mailchimp’s is the way that you can 'type onto' your e-newsletter: you just point at the copy on the e-newsletter you want to tweak and you can edit it there and then, in situ.

By contrast, with Mailchimp, you have to select the component you want to edit, and then make your changes in a separate box. Not a showstopper really, but it can occasionally slow you down a bit.

However, and as discussed above, it’s much easier with Mailchimp to see what your email will look like on different devices.

Opt-in processes in Aweber and Mailchimp

There are two ways you can add subscribers to a mailing list: using a 'single opt-in' or a 'double opt-in' process.

When you use a single opt-in process, the person completing your sign-up form is added to your mailing list immediately. With a double opt-in process, the person signing up to your list is sent an email containing a confirmation link that he or she must click before they are subscribed.

The main benefits of a single opt-in process are that

  • it makes it easy for users to subscribe

  • it generally improves conversion rates and leads to more people joining your list

 A double opt-in process is better for

  • keeping 'spam' and 'fake' email addresses to a minimum (because everybody on the list effectively has to prove that their email addresses are real)

  • improving the accuracy of reports (because open rates are based on the actions of subscribers with real email addresses, not a bunch of fake emails).

For some time, Aweber had a huge edge over Mailchimp in this area, because it allowed users to make use of either a single or a double opt-in approach.

Mailchimp recently changed its tune however,  allowing its customers to use a single opt-in approach, because the company found that 61% of users completing double opt in data capture forms were not completing their sign up process.

So a thumbs up to both products in this department.

Data segmentation

A key part of managing a mailing list involves creating segments and sending e-newsletters to them. Both Mailchimp and Aweber allow you to create segments based on your preferred criteria - but what they don't do is let you send to multiple segments at once.

For example, say you're a Volkswagen dealer with a mailing list containing a field called 'car model.' You've used field this to segment your mailing list neatly into the owners of VW Polos, Golfs, Passats, Tiguans etc. You have a special offer which is relevant to Polo and Golf owners, and you want to send this message to those two segments in one go.

But with Mailchimp's entry level plan and can't. You'll have to go and create a brand new segment for people who own Polos OR Golfs.

Now, this might not seem like a serious problem, but if you regularly need to send mailouts to multiple (and varying) segments of subscribers then you will potentially have more work to do than you might like.

If segmentation is a key aspect of how you manage your mailouts, then I'd probably look elsewhere for an email marketing solution. The two products I've come across which cater best for emailing multiple segments (and indeed lists) are Getresponse (note: its segments are called 'custom filters') and Campaign Monitor (which offers extremely good segmentation functionality, but at a pretty high price).

To be fair, you can get some advanced segmentation functionality with Mailchimp - but at a price (you'll need to add $199 to your Mailchimp bill). You can find out more about advanced segmentation in Mailchimp here

A nice touch in Aweber: stock images

One nice feature in Aweber which isn’t currently available in Mailchimp is a free stock images library.

You can use this to insert royalty-free photography into your e-newsletters - this is handy for all those times you need a generic looking picture of a computer keyboard to use as a thumbnail…

Split testing

An important feature of email marketing tools like Aweber and Mailchimp is split (or 'multivariate') testing.

Split testing allows you to try out different subject headers or content on sample data to see which works best. For example, you could send two versions of your e-newsletter to 10% of your subscribers, analyse the results (i.e., open / clickthrough rates) and send out the best-performing version to the remainder of people on your list.

If you have a large mailing list, use of split testing can lead to significant improvements to your open and clickthrough rates, so sany emarketing tools automate the process for you.

On the cheaper ‘Grow’ Mailchimp plans — the ones that are broadly comparable to Aweber in price — you can test three different versions of your email against each other.

More sophisticated split testing options are available in Mailchimp if you're prepared to pay for them - subscribers to Mailchimp's 'Pro Marketer' plan can test 8 variants of e-newsletters against each other. This is undoubtedly useful, but as this will cost you $199 per month on top of whatever you are paying to host your list, it's probably going to be a feature that only large organisations, with correspondingly large budgets, will avail of.

Up until recently Aweber trumped the standard Mailchimp offering on split testing, by allowing users to split test 4 different emails against each other.

More recently, this limit has been reduced to three — making the offering fairly similar with regard to split testing. I suppose Mailchimp is nonetheless the winner in this department however, simply because it does provide a way increase the variant count.

If you need more extensive split testing options and don’t have an extra $199 per month to spend, then Getresponse, with its limit of 5 variants, is worth investigating. Other leading products are not as good as Mailchimp or Aweber on this front (Campaign Monitor, for example, only permits a split test involving 2 variants; Mad Mimi doesn’t facilitate A/B tests at all).

RSS to e-newsletter

One thing that is definitely better in Mailchimp than in Aweber is the way that you can use an RSS feed (typically from a blog) to create e-newsletters.

Both platforms allow you to send out e-newsletters automatically based on an updated RSS feed. In Mailchimp, you can use any template to do so, but in Aweber, you're restricted to using a set of very dated, hard-to-edit templates.

This has negative implications for the consistency of your branding across your communications - you might spend some time, for example, creating a slick template in Aweber for your e-newsletters only to find that you can't use it for broadcasting blog posts.

If RSS-to-email is an important feature for you, Mailchimp is definitely preferable to Aweber. In fact, the RSS-to-email functionality in Mailchimp is stronger than other leading email marketing platforms too, including Campaign Monitor and Getresponse (which also insist on you using RSS-specific templates and not the standard range).


Both Aweber and Mailchimp provide you with detailed statistics on the performance of your mailouts, with, in my view, Mailchimp having the better reporting interface and one that is more feature packed.

It’s laid out in a way that makes drilling down into particular bits of data very straightforward - you can view e-newsletter results by activity (opens and clicks etc.), URLs clicked, social activity, e-commerce, conversations and Google Analytics.

There are two particularly nifty features in Mailchimp that are worth singling out for attention:

  • a ‘member rating’ system - Mailchimp reviews how engaged each member of your mailing list is (based on opens, clicks and purchases) and assigns them a member rating (using a five point scale). This allows you to identify particularly ‘good’ members of your mailing list easily and craft specific communications for them.

  • the option to compare your list’s performance against industry standards (i.e., you tell Mailchimp what sort of business you’re operating and it will compare your stats against campaigns by similar businesses).

Reporting in Mailchimp

Reporting in Mailchimp

Aweber is not without its strong features when it comes to reporting either however, and I particularly like the way that you can create segments directly from reports (i.e., you can look at a report for a particular e-newsletter broadcast, go to a list of people who’ve opened that email, and target them with a new communication on the spot).

This is not easily doable in Mailchimp: to create a segment of subscribers based on clickthroughs or open rates, you need to open your report, export a list of the relevant subscribers, and then re-import it (making sure that there is a field which flags the fact that these subscribers have engaged with the mailout). Messy!


Aweber and Mailchimp both integrate with important e-commerce and social platforms — key examples include Shopify, Bigcommerce, Paypal and Facebook.

However, Mailchimp offers a much bigger selection of integrations. It’s seen, for whatever reason, as more of an industry standard tool than Aweber, so some web applications — key examples being Squarespace and Shopify — will offer Mailchimp as a default ‘works out of the box’ e-marketing option. That's not to say that you can't use Aweber with these products, but there will be a bit more configuration required.

Additionally, Mailchimp is more tightly integrated with Facebook ads. You can connect a Mailchimp list to Facebook, which will then automatically examine its addresses and show ads to anybody on your list who also has a Facebook account (this is called a 'custom audience').

Importantly, your Mailchimp list is synced with your Facebook account, meaning that Facebook will automatically start showing the ads to any new subscribers (i.e., in addition to the people who were on your list when you connected your accounts).

Now, you can do this with a Aweber list too, but you will have to upload your list manually periodically to ensure that new subscribers continue to see your ads.

On top of this, you can actually run Facebook ad campaigns (and indeed Google ad campaigns) from within your Mailchimp account, so if you're the kind of user who wants to manage everything in one place, you may find this useful.

Send time optimization

A strong feature that is included in Mailchimp which is unfortunately not present in Aweber is ‘Send Time Optimization’.

Send time optimization is a sophisticated feature which automatically sends your e-newsletter at the time at which it is most likely to be opened. This time is calculated by Mailchimp based on looking at when the subscribers on your list have previously opened mail — it can work this out based on looking at the campaigns you’ve previously sent and also by using data from campaigns sent by other Mailchimp users which feature email addresses that are also present on your list.

As Mailchimp explains:

Since MailChimp has 4+ million users, we look globally at each email address’ engagement in deciding the best time to send to your list. Chances are the email addresses on your list receive email from other MailChimp users. That means that even if you’ve never sent to your list or only sent a few times, we can still provide a recommendation.

It’d be great if Aweber could consider adding this functionality, as it has the potential to significantly increase open rates.

Using different languages in Mailchimp and Aweber

For users wishing to provide versions of their confirmation emails and thank-you pages in different langauges, Mailchimp is a better choice than Aweber, as it provides this functionality out of the box. 

Setting this up is a bit fiddly however, and involves creating different merge tags for each language.


It’s a clear win for Aweber when it comes to support: you can get phone support, live chat and email support whereas Mailchimp only provides email support (and only after you’ve been forced to search their website for an answer to your query first). 

Aweber's phone support is 8am-8pm ET, Monday to Friday, and its live chat / email support is available 24/7. The company has won Stevie awards in 2016, 2017 and 2018 for their customer service too, which speaks well for the quality of their support.

So if you are a complete novice to e-marketing, but don't have the resource to hire somebody in to set your e-newsletter campaigns up, the availability of phone support for Aweber is something bear strongly in mind as an important advantage of using the platform.

Indeed, phone support is something of a USP for the product, given that many of of its leading competitors — Getresponse, Mailchimp and Campaign Monitor — simply don’t offer it.

Alternatives to Mailchimp and Aweber

Before deciding conclusively on Mailchimp and Aweber, it's worth taking a quick look at some alternatives:


For me, an obvious alternative to both Mailchimp and Aweber is Getresponse. Depending on your list size, it will usually come in cheaper than both Mailchimp and Aweber (particularly if you pay upfront for a year or two years), and it’s feature packed (offering landing pages, webinars and a CRM tool in addition to the features outlined above).

And it is MUCH more flexible than either Mailchimp or Aweber when it comes to emailing segmented data and managing multiple lists. 

You can read our full Getresponse review here or try the product free here.

Campaign Monitor

Another option is Campaign Monitor — this is a feature-rich tool which provides some very attractive templates (arguably best-in-class), along with strong functionality in the segmentation and marketing automation departments.

However, it's extremely expensive by comparison to any of the other products under discussion here. Read our Campaign Monitor review for more information.

Mad Mimi

Mad Mimi is one of the cheapest email marketing tools available - but also one of the most basic. It's good for users who just want to send very simple e-newsletters or run basic drip campaigns and don't have much money. But it's not in the same league as the other products under discussion in this comparison, especially Mailchimp and Getresponse. Check out our Mad Mimi review for more details.

Aweber vs Mailchimp: pros and cons summary
