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.
Either way you go about it, you’re supported by one of the best drag-and-drop email builders in the biz. Sendinblue’s editor makes it easy to whip up incredibly designed, personalized messages that you can utilize in any number of autoresponse sequences.
This platform has all the tools you need at your disposal. Set up automated welcome sequences when new subscribers or leads join your list. These can be as straightforward or complex as you’d like—from a simple welcome message to a series of precisely timed emails to warm a prospect up.

For organizations that need the paid plans, the price is still very competitive and the premium features will pay for themselves many times over.
#7 – Mailchimp Review — The Best for Beginners
Tip: the better your email segmentation strategy, the easier it will be to leverage personalization, especially at scale.
Campaign Management
With some of the other email autoresponders, you’ll have to configure things to make sure they work with your online store. Klaviyo is built for just that. This means less work on your end to get products in front of your customers.
Without writing a single line of code, you can gain quick mastery of a deep set of email automation features that include:

- Five types of subscription forms
- Direct SMTP service
- Cart abandonment

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.
At the Plus and Professional pricing tiers, you have more features like webinars, as well as greater degrees of customization.
And much more. Honestly, the Basic plan is far from basic.
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:
- Moosend – Best for simple marketing automation
- Constant Contact – Best for complex email sequences
- Sendinblue – Best free email autoresponder

Nurture individual leads from a 10,000-foot view by using the features in Klaviyo’s extensive toolkit:

That way, not only can Constant Contact know exactly when and from whence someone opted in, but the custom data fields can also serve as unique triggers for sending personalized automated emails.
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.
Millions of companies have seen 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
Disclosure: This content is reader-supported, which means if you click on some of our links that we may earn a commission.
But with unlimited contact storage, Sendinblue’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.
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
MailerLite is used by more than one million companies, startups, and freelancers because it is an intuitive, budget-friendly platform that delivers 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
As your contact list grows, it’s going to include more diverse customers at different stages of their buying journey.
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.
Today, it functions as an integrated marketing platform, taking on way more responsibility than the email automation it became famous for.
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.

#2 – Constant Contact Review — The Best for Complex Email Sequences
Better still, you can set it up in mere minutes. Sendinblue delivers several prebuilt automations that are perfect for setting autoresponses to common situations.
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.
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.
#6 – MailerLite Review — The Best Standalone Email Autoresponder
And, if you want to handle more than 300 per day, just upgrade to the Sendinblue plan that fits you best. Prices start $25 per month for up to 20,000 monthly emails.
Despite its depth, I like Mailchimp as an email autoresponder for beginners because it’s constantly offering user recommendations based on intelligence from billions of email interactions.

- SEO – unlock massive amounts of SEO traffic. See real results.
- Content Marketing – our team creates epic content that will get shared, get links, and attract traffic.
- Paid Media – effective paid strategies with clear ROI.
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.
Most other tools restrictively cap this aspect of their free plans to encourage you to upgrade.
This is a whole new way to approach customers where they are.
The end goal is setting up something that automatically sends the right message, to the right customer, at the right time.
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.
For one, GetResponse offers hundreds of professionally designed templates to communicate with customers at every step of their journey.

That’s just shy of 10,000 autoresponses per month, more than enough to supercharge your marketing and sales efforts.
Moosend also offers customized enterprise-grade plans for any list size. This includes a dedicated IP, SSO and SAML, priority support, and an account manager.
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.
I like all of these email autoresponders because they help you benefit from the unavoidable trial-and-error associated with email marketing.
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.
The clean MailerLite interface gives your teams the control they need to communicate effectively with your subscribers.
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?
Conclusion
With other email autoresponders, you’re going to have to integrate your pipeline. With GetResponse, you can keep daily operations under one roof.
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.

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 Mailchimp API or SMTP
Its free version lets you send 12 emails per month to 1,000 subscribers, which might be all some people need to get started.
The contacts who make up your list are different people. That should go without saying.
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
Sendinblue has the most generous free package on this list, and it only gets better when you upgrade to a paid plan.
Here are the major features of email autoresponders that are helping companies increase their chances of success:
Automation Capabilities
It’s almost unreasonably generous.
They’ve recently added “And/Or” expressions to custom fields. This allows for a lot more customization in terms of defining triggers. Custom fields don’t have to be just one thing any more!
GetResponse works well for sales teams because you’ve got conversion funnels and the ability to host webinars is baked in.
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
Subject Line Helper, for instance, offers data-driven insights about how to increase open and click rates.
But, even today, many companies rely on email blasting their full list to get the word out.
That said, if you already have a way of tracking contacts, GetResponse integrates with popular tools like Magneto, Microsoft Dynamics, and Salesflare.
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.
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.
And, with the simple user interface, anyone on your team can start maximizing the relevant content every visitor sees.

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.
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.
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
Many people begin the search for an email autoresponder only to discover that what they actually need is an email marketing platform.
Automated, personalized emails go well beyond using a contact’s name in the subject line.
Let’s walk through the best email autoresponders, what they can do for you, and how to select the right one.
#1 – Moosend Review — The Best for Simple Marketing Automation

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
Effective email campaigns are based on putting things in front of customers that they actually want.
Plus, you can use this automation capability to set up nuanced drip campaigns to keep the engagement up without too heavy a touch. Constant Contact’s custom form fields allow to get as granular as you’d like with long-term strategies for communicating with your list. And you can 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.
Others help you set up complex automated workflows that respond to customer behavior, shopping tendencies, and other triggers you define.
Staying effective in the long term means making adjustments. Campaign management tools help you figure out what’s working and what to change.
