You know the revenue is out there, and you know email can help you get it. But how do you keep a strong handle on your campaign as it plays out over weeks and months?

Email autoresponders can save you a ton of time and deliver huge returns on campaign investment. Yet automation can be a double-edged sword.

The sad truth is that many thoughtful email campaigns become inbox wallpaper. It only takes a few mistimed or off-target emails before your audience starts to tune them out.

A good email autoresponder gives you the ability to connect with customers, at scale, without overwhelming them

Or your team, for that matter. These products eliminate many of the tedious and repetitive tasks that are so essential to building relationships at scale.

Delight your customers with content they’re interested in. Get full visibility into your open and click-through rates–watch them climb.

Let’s walk through the best email autoresponders, what they can do for you, and how to select the right one. 

#1 – Constant Contact Review — The Best Overall

Constant Contact is a full-scale email autoresponder. If you’re interested in automating your processes, this is my top recommendation, which you can try for free for 60 days, no credit card needed.

Set up automated welcome sequences when new subscribers or leads join your list. These can be as straightforward or complex as you would like—from a simple welcome message to a series of precisely timed emails to warm a prospect up.

Constant Contact welcome email sequencing for Best Email Autoresponder

Easily embed the customizable form builder on your websites and landing pages to capture your list members’ info, letting you know exactly when and from where someone opted in. What’s more, the custom data fields can serve as unique triggers for sending personalized automated emails.

You can set up one welcome sequence track for salespeople, another one for C-suite executives, and so on. Not only can you tailor your messages to be precisely targeted to segments of your list, but you also get more actionable data. No more weak open rates that are only the result of inundating every subscriber with the same welcome sequence.

This obviously goes well beyond the first messages you send. 

You can set autoresponder triggers at key points along the way, such as clicking a specific link within an email. If your recipient has a birthday or anniversary coming up, you can send an automated email message containing a special offer. Or if a recipient doesn’t open an email the first time, you can set a waiting time to resend the message.

Use this automation capability to set up nuanced drip campaigns to keep the engagement up without too heavy a touch. Set automated emails to only send on specific days of the week or times of the day, so you’re always sending messages that get seen.

You can sync products from your Shopify, eBay, or Etsy accounts within your email marketing campaign. 

All this functionality is available in Constant Contact’s Standard plan, the cost of which is determined by the number of contacts in your list:

  • Up to 500 contacts: $35/month
  • 501 – 1,000 contacts: $55/month
  • 1,001 – 2,500 contacts: $75/month
  • 2,501 – 5,000 contacts: $110/month
  • 5,001 – 10,000 contacts: $160/month
  • 10,001 – 15,000 contacts: $210/month

Pricing continues to scale upward to 50,000 contacts. Above that, Constant Contact will set up a custom price for you. Constant Contact will provide discounts for those who prepay for their services. Nonprofit organizations also potentially can receive a discount.

#2 – Moosend Review — The Best for Simple Marketing Automation

Moosend splash page for Best Email Autoresponder

Moosend is an affordable email automation tool with an almost nonexistent learning curve. Yet for how easy it is to get started, Moosend users wind up automating their email marketing in really impactful ways.

It’s sad to think, but some companies spend thousands of dollars a month on ultra-powerful marketing automation software that they don’t really need. Plus, that stuff can be really hard to use.

With Moosend, you get a lot of freedom to customize your email marketing automation. There’s a rich set of triggers and actions all managed in a drag-and-drop interface. Workflows can be shared among team members, who can leave notes.

The Moosend interface itself is great at educating users how to automate and fine-tune customer journeys. With templates, preset workflows, and rich tracking capabilities, Moosend makes it simple to find what works for your unique subscriber base.

Moosend similar users feature for Best Email Autoresponder

#3 – Brevo (formerly Sendinblue) Review — The Best Free Email Autoresponder

Brevo marketing automation landing page.

Brevo (formerly Sendinblue) has one of the most generous free plans I’ve seen for marketing and email automation software. Their free forever option is limited, of course, in some ways, but still offers unlimited contact storage.

Most other tools restrictively cap this aspect of their free plans to encourage you to upgrade.

But with unlimited contact storage, Brevo’s free version of its autoresponder truly can’t be beat. You can have it send up to 300 emails per day on your behalf.

That’s just shy of 10,000 autoresponses per month, more than enough to supercharge your marketing and sales efforts.

Better still, you can set it up in mere minutes. Brevo delivers several prebuilt automations that are perfect for setting autoresponses to common situations.

Put welcome emails and double opt-in mechanisms to new list members on autopilot, have messages send automatically when a subscriber interacts with a portion of your website or a previous email, or have anniversary, birthday, follow-up, and reminder emails delivered without any manual effort on your end.

And the possibilities become endless if you utilize Brevo’s automation builder. There, you have full control over trigger actions (like an abandoned cart, among many others), timing, conditions, and qualifiers.

Either way you go about it, you’re supported by one of the best drag-and-drop email builders in the biz. Brevo’s editor makes it easy to whip up incredibly designed, personalized messages that you can utilize in any number of autoresponse sequences.

And, if you want to handle more than 300 per day, just upgrade to the Brevo plan that fits you best. Prices start $25 per month for up to 20,000 monthly emails.

With such a good free option on offer, there’s no excuse not to try out Brevo today. Gain back valuable time and energy while ensuring that you are giving your email list all the attention they require.

#4 – Klaviyo Review — The Best for Ecommerce

Klaviyo ties into a CRM or ecommerce platform and makes it easy to deliver ultra-personalized content via email. It really plays well with other software, like WooCommerce, BigCommmerce, Magento, and other big-name ecommerce brands.

#5 – Omnisend Review — The Best for Multichannel Ecommerce

Omnisend's interface.

Omnisend is a powerful email and SMS marketing platform that excels in delivering seamless multichannel campaigns at affordable pricing. It provides strong value for your money, helping to bust the relentless myth that e-commerce stores need to spend a lot on email marketing.  

It easily integrates with popular e-commerce platforms such as Shopify, Magento, WooCommerce, and BigCommerce, allowing you to leverage customer data to create highly personalized content.

Thanks to its native integration with customer data sources, you can finely segment your audience based on various parameters, providing targeted and relevant messaging to different customer segments.

Unlike some other email autoresponders, Omnisend is specifically designed for seamless integration with online stores. This means less time spent on configuration and more time focused on effectively showcasing your products to your customers.

#6 – GetResponse Review — The Best for Sales Teams

GetResponse has provided one of the simplest, most effective email autoresponders for more than 20 years. Over that time, they’ve added features and evolved the UI to keep it one of the most useful products on the market.

Their experience shows. They know what works, why, and how to help you get set up. 

For one, GetResponse offers hundreds of professionally designed templates to communicate with customers at every step of their journey.

GetResponse templates for Best Email Autoresponder

The built-in sales tracking features are also really nice, and really set GetResponse apart from the other easy-to-use autoresponders. Even their Basic plan comes with a sales funnel, unlimited lead funnels, and unlimited landing pages.

With other email autoresponders, you’re going to have to integrate your pipeline. With GetResponse, you can keep daily operations under one roof.

That said, if you already have a way of tracking contacts, GetResponse integrates with popular tools like Magneto, Microsoft Dynamics, and Salesflare.

Along with a flexible email autoresponder, GetResponse has a number of other useful features to help you connect with customers:

  • Unlimited email sends
  • Transactional and time-sensitive emails
  • Drag-and-drop email editor with mobile and inbox preview
  • Add content blocks, videos, buttons, and social media icons to emails
  • A/B testing
  • List and calendar views for email scheduling
  • RSS-email templates

GetResponse doesn’t have a free forever plan, though they do offer a free trial. Pricing starts at $13.50/month for 1,000 contacts with their Basic plan, which comes with all the features listed above. 

And much more. Honestly, the Basic plan is far from basic.

At the Plus and Professional pricing tiers, you have more features like webinars, as well as greater degrees of customization. 

Their top tier plan, Max, comes with a dedicated IP address, SSO, and other features designed to secure and streamline enterprise email marketing and sales. Try GetResponse for free today.

#7 – MailerLite Review — The Best Standalone Email Autoresponder

MailerLite is used by more than one million companies, startups, and freelancers because it is an intuitive, budget-friendly platform that delivers results. 

Its free version lets you send 12 emails per month to 1,000 subscribers, which might be all some people need to get started.

For an email autoresponder that’s easy to use, MailerLite comes packed with simple, yet powerful features that help you optimize your campaign. 

I like using A/B split testing to send two variations of an email and see which one performs better.

MailerLite A/B testing for Best Email Autoresponder

The clean MailerLite interface gives your teams the control they need to communicate effectively with your subscribers. 

Some of its best features include:

  • Automate RSS to email
  • Time-zone based email delivery
  • Auto resend unopened emails with alternative subjects or personal messages
  • Segment subscribers based on a varied criteria
  • Rich email personalization
  • Target specific interest groups by tagging subscribers or inviting them to self-select
  • Track email campaign activity with detailed reports
  • Click maps to analyze subscriber interaction with your emails

MailerLite also comes with features to customize your website experience, like pop-ups and embedded forms, as well as an amazing drag-and-drop editor to craft striking newsletters.

Better still, it’s very affordable beyond the free version.

  • Free: Up to 1,000 subscribers, 12,000 monthly email limit
  • $10/month: Up to 1,000 subscribers, unlimited emails
  • $15/month: Up to 2,500 subscribers, unlimited emails
  • $30/month: Up to 5,000 subscribers, unlimited emails
  • $50/month: Up to 10,000 subscribers, unlimited emails

As a free email autoresponder, MailerLite is hard to beat for any small business. You get a free website with five landing pages, a drag-and-drop visual email editor, and advanced segmentation features.

It’s almost unreasonably generous.

For organizations that need the paid plans, the price is still very competitive and the premium features will pay for themselves many times over.

#8 – Intuit Mailchimp Review — The Best for Beginners

Intuit Mailchimp is a powerful product that hasn’t lost its simple feel, though it has grown considerably since it first hit the market in 2001. 

Today, it functions as an integrated marketing platform, taking on way more responsibility than the email automation it became famous for.

Despite its depth, I like Intuit Mailchimp as an email autoresponder for beginners because it’s constantly offering user recommendations based on intelligence from billions of email interactions. 

Mailchimp builder for Best Email Autoresponder

Subject Line Helper, for instance, offers data-driven insights about how to increase open and click rates. 

There are plenty of other excellent features, including:

  • Drag-and-drop email editor
  • Segmentation capabilities to target messaging and automate product recommendations
  • Send Time Optimization
  • Multi-branch customer journeys
  • Behavior-based automation
  • Lookalike audience finder
  • RSS to email 
  • Transactional Emails with Intuit Mailchimp API or SMTP

Intuit Mailchimp offers a free forever version that’s limited to 2,000 contacts, but comes with features like a marketing CRM and landing pages that you won’t get with other freemium email autoresponders.

To get the Customer Journey Builder, which lets you construct workflows in a visual editor, you will need one of the paid plans:

  • Essentials: starting at $9.99/month for 500 contacts
  • Standard: starting at $14.99/month for 500 contacts
  • Premium: starting at $299/month for 10,000 contacts

Some of the aforementioned features, like predicted demographics or the lookalike audience finder, are only included with Standard and Premium.

Millions of companies have seen Intuit Mailchimp increase their ROI. You can get started with the free version today, knowing that they also have tools to help you grow.

What I Looked at to Find the Best Email Autoresponder

Email autoresponders can help your teams get more done in less time, without sacrificing the personal touch that drives clicks. However, not all email autoresponders are created equal. 

Some will work well for a brief series of 3-5 emails that welcome a new contact and warm them to your products—good for a simple customer journey.

Others help you set up complex automated workflows that respond to customer behavior, shopping tendencies, and other triggers you define.

The end goal is setting up something that automatically sends the right message, to the right customer, at the right time. 

Here are the major features of email autoresponders that are helping companies increase their chances of success:

Automation Capabilities

It’s right there in the name—the big boon of autoresponders is automating menial, manual campaign tasks. 

However, the more robust tools tie into your customer databases or CRM, and let you define triggers based on a range of highly-personalized criteria.

Some of the popular automation capabilities you will see include:

  • Welcoming/Onboarding: Greet new users, customers, or employees
  • Web Trigger: Make contact when someone clicks on a link, fills out a form, updates a field, makes a purchase, or joins a group
  • Reminders: Send time-sensitive emails about deals or webinars
  • Celebrations: Send discounts for birthdays and anniversaries
  • VIP: Trigger discounts and promotions for loyal customers 
  • Abandoned cart: Contact a customer with the opportunity to buy items left in their cart
  • Follow up: Reach out after a purchase or interaction
  • A/B testing: Experiment with different versions of the same email to analyze performance and evolve your strategy
  • Branch flows: Create workflows that split customers based on conditional or logical triggers to direct them down the most appropriate path

A really good autoresponder lets you build out workflows within a visual editor, giving you a bird’s eye view of each trigger and step of the process. 

Make sure you pick something with the capabilities you need to design each customer’s entire journey.

Email Editor

Don’t forget about crafting great emails. They have to be appealing from the subject line to the CTA, and every element must be optimized for web and mobile.

Good email autoresponders make these challenges much easier. My favorite products have intuitive visual email builders that help you make content that converts. 

Beyond designing beautiful emails quickly, you can add buttons, embed content, and preview exactly what your email is going to look like from a customer’s point of view.

Find an autoresponder with an email editor that your employees enjoy using that also delivers predictable results. 

With it, you’ll find that your teams will be able to quickly generate on-brand emails, consistently building out the perfect message for each step of a customer’s journey.

Email Segmentation 

The contacts who make up your list are different people. That should go without saying. 

But, even today, many companies rely on email blasting their full list to get the word out.

Effective email campaigns are based on putting things in front of customers that they actually want. 

Email segmentation allows you to leverage customer data in service of better targeting, through which you can differentiate your contact list into groups based on:

  • Age
  • Average spend
  • Cart contents
  • Gender
  • Geolocation
  • Past purchases
  • Weather conditions
  • Website behavior

Companies like Starbucks are sending weather-appropriate discounts on drinks: it’s no accident when their emails entice consumers to warm up on a rainy day or cool off when the temperature spikes.

This is a whole new way to approach customers where they are

Every company defines their important segments differently. The richer your customer data, the easier it will be to use email segmentation to increase your conversion rate.

Email Personalization

Automated, personalized emails go well beyond using a contact’s name in the subject line. 

With Klaviyo, for example, you can automate the inclusion of product recommendations in the body of your email based on a contact’s location, past purchases, current weather, and so on. 

Some autoresponders leverage machine learning to suggest products that other shoppers with similar tastes have ordered. 

The best tools help you nail the easy stuff—like greeting subscribers by name and remembering their birthdays—while helping you convert customer data into revenue.

Tip: the better your email segmentation strategy, the easier it will be to leverage personalization, especially at scale.

Campaign Management

As your contact list grows, it’s going to include more diverse customers at different stages of their buying journey. 

You are going to want an email autoresponder that gives you the ability to manage this growing list and provides visibility into the ongoing performance of your campaign.

We all know about open rates and click-through rates. Those are important, but make sure you find something that lets you drill down into what matters at the end of the day, like sales per email, ROI per email, and total sales per email sent.

Staying effective in the long term means making adjustments. Campaign management tools help you figure out what’s working and what to change.

Email and Subscriber Limitations

Typically, email autoresponder pricing is based on the number of subscribers you have and the number of emails you send each month.

This should be a pretty straightforward consideration. But if your goal is growth, factor in how many more you’re looking to add to your list over the next month, quarter, or year.

If your email marketing strategy takes off and you need to bump up into a higher pricing tier, will that be a problem for your budget and ROI?


Many people begin the search for an email autoresponder only to discover that what they actually need is an email marketing platform. 

Every tool I’ve included on my list of top products handle more than a simple autoresponder. Here’s the entire list one more time:

  1. Constant Contact – Best overall
  2. Moosend – Best for simple marketing automation
  3. Brevo (formerly Sendinblue) – Best free email autoresponder
  4. Klaviyo – Best for e-commerce
  5. Omnisend – Best for multichannel
  6. GetResponse – Best for sales teams
  7. MailerLite – Best standalone email autoresponder
  8. Intuit Mailchimp – Best for beginners

All things being equal, Constant Contact is the best bet for most people who need an email autoresponder. It’s affordable, easy to use, and gives you the tools to figure out which email strategies are working.

The closest option on this list to a dedicated email autoresponder is MailerLite, which still comes with way more than simple email automation capabilities. It’s a really good option (and price) for companies that already have great CRM software and really just need the email autoresponder capabilities.

Brevo has the most generous free package on this list, and it only gets better when you upgrade to a paid plan.

Omnisend offers different integrations and channel functionalities to serve as a versatile fit for many marketing needs.

Intuit Mailchimp and Moosend are more feature-rich than MailerLite, but both remain incredibly easy to use for non-specialists.

GetResponse works well for sales teams because you’ve got conversion funnels and the ability to host webinars is baked in. 

Klaviyo is probably the most comprehensive tool on this list, and it works incredibly well at automating the processes necessary to run a successful email ecommerce campaign.

I like all of these email autoresponders because they help you benefit from the unavoidable trial-and-error associated with email marketing. 

No campaign is ever going to be perfect, but the right tools will help you continually evolve your strategy to meet your customers where they are.
