Best for: Online Event Organizers, Educational Institutions

Unique feature: Event invitations management

Constant Contact is among the oldest autoresponder tools in the market. The software has an easy-to-use drag-and-drop email builder to create your newsletters. Apart from autoresponders, Constant Contact also lets you choose between different email types, including event registrations, A/B Testing, and surveys.

Regarding email automation, the autoresponder software lets you create abandoned cart campaigns for your eCommerce store. Its best feature, though, is its event invitations management tool that enables you to simplify the way you manage your online events. The RSVP feature will also give your webinars and online courses the boost they need and even allow you to collect responses straight from the automated email you sent.

The autoresponder tool also equips you with personalization options to make your automated messages more effective. However, it’s worth mentioning that while you can add your contact information, you can’t use if/then logic, unlike other Constant Contact alternatives like Moosend with more sophisticated personalization features.

  • Basic personalization and email list segmentation
  • RSVP tool to manage online events more effectively

Pricing: Limited free plan, paid plans start at $15/month

Best for: Agencies, eCommerce, Publishers

Unique feature: Multi-step custom workflows

Mailchimp is one of the most well-known email marketing autoresponders you’ll find out there. The platform sports a very clean template editor you can use to create your automated messages in a few minutes. You can then use Mailchimp’s robust autoresponder features to deliver your auto-responses into your email subscribers’ inbox.

While Mailchimp’s email editor and autoresponders are pretty solid, its email automation features might be difficult to handle. The platform will also give you access to personalization and email list segmentation. However, their complexity might not be ideal for first-time users. The lack of a workflow editor will also make things a bit difficult, unlike other popular Mailchimp alternatives that are more user-friendly.

What makes Mailchimp’s autoresponder so famous (and compensates for the lack of user-friendly automation) is its advanced reporting and analytics capabilities. Through them, you can track all the email metrics you need to improve your email marketing campaigns and boost your conversions.

Best Autoresponder Features

  • Multi-step custom workflows to target your audience
  • Predictive insights to improve your marketing campaigns
  • Email newsletter templates you can customize

Moreover, AWeber is a great email list management tool to keep your contact lists clean and promote your email deliverability.

When it comes to streamlining your marketing efforts, integrations are a big plus for the autoresponder.
