Autoresponder Softwares - 4 Best Tools for Automating Emails

The one mistake which costs marketers a lot is the assumption that once someone joins their list, they can just send them newsletters and ‚Äėemail blasts‚Äô to convert them into customers.¬†

What you need to do instead is to guide them through the journey with a welcome email telling them what to expect from your emails, and guide them about the problems your product solves and how they will benefit. 

Doing this for all subscribers sounds insane… but only if you were doing it manually. 

Thankfully, all major email service providers (ESPs) provide autoresponders.

What is an Autoresponder?

Autoresponders are simply a sequence of automated emails that are sent to a subscriber, based on a trigger event. And once you’ve set up an autoresponder, it should run with virtually no maintenance required.

We have prepared this short guide for you to evaluate different autoresponders based on features, pricing, ease-of-use, etc. You can take your pick and explore further according to your business requirements.

Which Autoresponder is the Best?

‚Äć1. SendX

This autoresponder gives you all the critical features you need to put your marketing on autopilot. 

What you can do:

  • Edit automation rules in the future to add or update either triggers or actions.¬†
  • Categorize different types of users in different user groups or lists & trigger emails based on their behavior.¬†

All this is made possible while maintaining a smooth user experience & intuitive interface. I think that gives it an edge over all the other autoresponders that lack the ease-of-use.

Their pricing structure is based on the number of subscribers in your list, and then you can send unlimited emails. Your pricing plan changes only when you grow your subscribers. You can access all the features at all pricing plans.

Pricing starts for as low as $7.49/month (when billed annually) and $9.99/month (billed monthly). 

Before you commit, you can take a 14-day free trial and get access to all the features.

2. Mailchimp

Mailchimp suggests using their automation but even their legacy autoresponder is powerful. 

What you can do:

  • Create essential autoresponders (Welcome email, order notifications, abandoned cart, RSS, etc), as well as more advanced options (e.g. e-commerce, tag-based).¬†
  • If one of your autoresponders uses a layout or includes content you like, you can save it as a template to reuse with other campaigns and automation.
  • You can get detailed analytics on all your emails that are part of the autoresponder sequence such as geo-locations, heat maps, and of course open and clickthrough rates.¬†


You can sign up for a forever free plan but that only allows you to access a few features. Forever Free plan: $0, 2000 contacts, 10K emails/mo.

The rest of the plans are based on a combination of features you use and the number of contacts you have. For 500 contacts, this would be the pricing: 

Essential plan: $9.99/mo, 500K emails 

Standard Plan: $14.99/mo 1.2M emails

Premium Plan: $299/mo, 3M+ emails

Then the pricing increases as your list count increases. And remember, the Mailchimp counts subscribers & unsubscribers to calculate the list count. 

Two drawbacks:

  • The main drawback is that their autoresponder editor isn‚Äôt the easiest to use.
  • Mailchimp's pricing starts off cheap but gets really costly as your audience increases. MailChimp is actually one of the most expensive autoresponder tools out there for small-to-medium businesses.¬†

If you are looking for a solution that’s best for a small and medium-sized business I’d encourage you to try SendX. 

You’ll be joining many other former Mailchimp users who’ve shifted to SendX and never looked back.

3. Constant Contact 

It offers a WYSIWYG editor to create an email campaign, secure contacts list management, social stats reporting tools, images/texts import feature, real-time tracking of your email campaign, etc.

What you can do:

  • Once the autoresponder series is created, you can select which lists the email will send out to. You can also add multiple lists to the autoresponder series as well.
  • Once the report is generated, you can view the queued contacts, sent, opens, and clicks for emails in your automated email series.¬†
  • Contacts don't open your email for a variety of reasons. So you have the option to trigger an email to automatically resend without having to figure out for yourself which contacts didn't open it.

The autoresponder feature is not available in a trial account. Upgrading your email plan gives you access to these additional features.


  • Email ‚Äď The plan starts with $20/mo for 1 user & lets you send unlimited emails along with features like 1 GB storage, list-building tools, e-commerce, customizable templates, apps & integration, live support & more.

  • Lite ‚Äď The plan starts with $5/mo for 1 user & lets you send 10000 emails per month, along with 500 MB storage, list-building tools, list segmentation, e-commerce & more.

4. SendInBlue

Their free plan offers a good range of advanced autoresponders, including welcome, anniversary, page visits, and e-commerce (such as product purchase or abandoned cart).
