The 6 Best Autoresponder Plugins for WordPress

If you run a website – whether it’s for your agency, an eCommerce store, or a community – you already know the ROI of email marketing. And when it comes to converting website visitors into valuable customers, having the right software can make all the difference.

When you search for the best autoresponder plugins on WordPress, you’re greeted by a never-ending list of tools to use. This makes settling on the right solution for you & your business difficult.

And although choosing an autoresponder may seem like a minor detail in the grand scheme of things, the wrong choice can burn a hole in your pocket and lower your conversion rate. So, in this article – we’ll walk you through what to look for in WordPress autoresponder plugins as well as what sets apart the good from the great ones out there.

What Makes A Great Autoresponder Plugin?

Every autoresponder comes with a whole host of features, so how do you know which one is right for you? Here’s a list of what we believe are the most important things your email marketing software should have:

Ease of Use – User Experience

As a business owner, you’re probably short on time and always rushing to do something. In that case, the last thing you need is an autoresponder with a messy interface and a steep learning curve. The autoresponder plugin you end up choosing should be one that you enjoy using, is easy to navigate and shouldn’t take you long to get set up. We prefer drag-and-drop tools over something that requires in-depth coding knowledge.

Integration with Other Tools

A great autoresponder should offer seamless integration with any marketing tools you use, especially your CRM platform.

Pro tip: Before getting any autoresponder, have a look at their integration list or ask their support team.

Automation Capability

The whole idea behind having an autoresponder is automating some of the manual labor that needs to be done for any business. However, not all of them are made equal. Some autoresponders integrate perfectly with your CRM and some don’t.

Let’s take a look at the automation capabilities that an ideal autoresponder must have:

  • Welcome Messages: You should be able to generate a message for new users or customers
  • Reminders: Send customers time-based emails so that they don’t miss out on great deals
  • Web Triggers: Make contact with users after they take an action on your site; like filling in form, clicking a pop-up, or providing personal details
  • Loyalty Offers: Generates special offers for loyal customers to make them feel more appreciated
  • Personalization: Provide a personal touch by sending discount offers on a customer’s birthday or anniversary.
  • A/B testing: The ability to experiment and optimize your emails to improve conversions
  • Cart Abandonment: Remind customers via email that they left their cart with products in it
  • Follow Up: Send an email after purchase or for the collection of reviews

Subscription Forms

Having a subscription form on your website is a must nowadays. It’s one of the easiest ways to grow your email list as people can sign up directly from your page, and bonus points if the software comes with a load of templates for you to get up and running right away.

Triggering Options

Triggers are actions that drive an automatic reaction. In our case, if a customer leaves a product in their cart, they get an email reminder. Or, if they subscribe to your forms, they get a welcome message. The best email marketing solutions have many preset automations with built-in triggers to choose from, as well as letting you customize your own.


Any great autoresponder should have robust analytics built-in. Tracking progress over time, recording user data, and figuring out which emails or lead generation forms perform well is an absolute must for anyone wanting to grow their email list on WordPress.

AWeber Pro is priced at $16.15 prt month when billed annually. You can customize your Pro plan and add several tools to make your plugin smoother. It is one of the cheapest tools for WordPress in the market, and this is due to the fact that it predominantly focuses on auto-responding.
