7 Great Marketing Software (Autoresponder) Platforms

An image representation of electronic mail communication.

I do email marketing for 2 sites.  I’ve been at it for years.

Over the years I’ve used several email marketing platforms (aka email autoresponders), so I have a decent idea as to what’s good and what’s bad.

There isn’t a one-size-fits-all which explains why several platforms thrive.

In 2020 I switched the Fat Stacks email list over to ConvertKit and couldn’t be happier, for reasons I explain below.  Before that I used AWeber and tried Mailchimp.  Long ago I tried GetResponse.  I’ve also done a free trial with Constant Contact going back a few years.

Please note that I have not used every email autoresponder platform available.  I’ve used several of the leading brands, but not all.

Here’s my list of the best email autoresponder services.

1. ConvertKit: Best for bloggers and course sellers

In 2020 I switched my Fat Stacks email newsletter to ConvertKit and am thrilled I did so.  It’s a decent amount of work moving to a new autoresponder, especially a service like ConvertKit which has a powerful tagging and automations features.

I spent a few days making the switch.  It took a bit of playing around with the software to figure it out.  I now have a decent handle on it.

Why did I switch to ConvertKit?  The main reason was that ConvertKit integrates natively with Teachable, which is the online course platform I use for selling the Fat Stacks courses.  When I was with AWeber, I had to use Zapier, which I don’t like because I couldn’t tag buyers of individual courses.   Because I sell several courses, I can provide a much better user experience by tagging each course buyer with a unique tag.  ConvertKit makes this possible.

ConvertKit has quickly become one of the most popular email marketing solutions on the market today. It is popular for good reason. The degree of control you have for segmenting users and creating sequences is incredible.  It was built from the start with this in mind instead of added after the fact like AWeber did.  The user interface has simple use buttons and guidance to help you set up workflows. There is a column on the right side that remains out of your way, but may be missed. One thing to keep in mind is that some of the features are hidden and you have to look for them, or already know where they are located.

ConvertKit has an easy to use email creator that includes what you see is what you get (WYSIWYG) editor. Most of the formatting in ConvertKit happens in a WYSIWYG editor, which is incredibly basic. This is great for a novice user but may leave a more advanced user feeling like something is missing.

ConvertKit allows you to customize your email, but there are limits to the customization. You can change the color, alignment, and size of the font. You can also add images and files if you would like. If you want to customize it any further, you will have to edit the code. Otherwise, the program comes with three basic templates to help you create a layout.

ConvertKit collects data and metrics about the emails that you send to your customers so you have reliable information you can use for future emails. ConvertKit allows you to send automated emails and you can trigger the emails based on the behavior of your customer. ConvertKit provides you a way to create quick forms and landing pages.

The plans with ConvertKit start around $29 a month but can go up in price. You are able to have 1,000 subscribers with the $29 price point. While they do not have any free plans, they do offer you a free trial for 14 days.


  • Very powerful and easy-to-use segmenting features.
  • Integrates with Teachable.
  • Awesome email newsletter editor (for text-based emails which I primarily send).
  • Incredible automation capability with sequences, tagging, etc.  You can control with a few clicks who gets your emails.  While this isn’t always necessary, when it is, it’s invaluable.


  • The interface takes some time to figure out. It’s more complicated than AWeber, but it’s worth learning.
  • The support is not good at all.  There is no real-time live chat.  It takes 24 hours to get a response which is unacceptable for cloud software IMO.  Nevertheless, I deal with this given the benefits.

2. Aweber: Best for simplicity

I still use AWeber for my small B2B site.  I stick with AWeber because for that site, AWeber does  the job just fine.  There’s no reason to spend time or money moving that list over to ConvertKit.

Up until my recent switch to ConvertKit for Fat Stacks, I used AWeber for years.  It served me well.  Deliverability was good.  The user interface is super simple and easy to learn.

However, the Achilles heal for me was that AWeber did not integrate with Teachable directly.  This was a dealbreaker.  Moreover, while AWeber has tagging, it’s not a good system.

Frankly, AWeber is outdated.  It was state-of-the-art in 2008, but new services have cropped up that were built with new tech and concepts in mind that work so much better.

While many folks still use AWeber, they do so because AWeber’s simplicity works for them.  If I didn’t sell courses, I’d stay with AWeber.


  • Very easy to learn and use.
  • Good deliverability.
  • Outstanding customer support.


  • Lacks integration with Teachable.
  • Weak tagging and automation capabilities.  The Campaigns feature is far too complex compared to ConvertKit.

3. Mailchimp: Best for fancy email templates

Mailchimp is like AWeber in that it’s been around for years.

Kudos to Mailchimp for enhancing it’s tech far better than AWeber incorporating tagging and automations.  The interface is far more current than AWeber as well.

However, after using Mailchimp for several months, I found it frustrating.  While it offers far more capabilities than AWeber, the user interface is very difficult to use.  I never developed a solid understanding of everything so it was like I was flying blind using it.

Another major dealbreaker is Mailchimp has some nonsense, vague policy against affiliate marketing.  It’s absolutely ludicrous that they make some statement that affiliate marketing is not acceptable but then they say you can include affiliate links.  I don’t understand it. I do affiliate marketing so I want nothing to do with this platform.

The one powerful feature Mailchimp offers is very slick email templates.  If you want to send out formatted, fancy emails with grids and images, Mailchimp is awesome.  They look great and are fast to set up with your own templates.  FAR FAR better than AWeber and ConvertKit in this regard.

Mailchimp also offers live chat support which is quite good.  Not as good as AWeber, but decent.  AWeber’s support is unmatched.  Every person is knowledgeable and super friendly.  I found Mailchimp’s support not the friendliest and wait times can be long.


  • Beautiful email templates.
  • Updated with decent segmenting capabilities.
  • Live chat support.


  • Expensive tiered plans.  The pricing is bizarre.  I ended up getting ripped off.  You have tiers by number of subscribers but also are capped with the number of emails that can go out.  If you email frequently, avoid Mailchimp at all costs.  I was wracking up fees like crazy.  Mailchimp needs to get rid of capped number of emails.
  • The interface can be challenging.  I never got a good handle on it.  In fact, I found it downright annoying.

4. Ontraport: Best for e-commerce stores

Ontraport is a complete customer relationship management (CRM) tool. It stores everything your customers do and manages it all behind the scenes so you do not have to.

Ontraport offers pricing plans. They range from $79 to $497 a month. The major difference in the cost has to do with the number of contacts you have. All of the plans provide you with one on one service to help you get on board. They do provide a discount if you pay annually instead of monthly.

In addition to superior customer service, they have a user based community available to provide assistance at any time. They have a ton of training options and articles to help you find the answers you need.
