Top 10 Autoresponder Software in 2025: Free & Paid Options Compared

What is an email autoresponder?

In simple terms, an email autoresponder is an automation tool that sends pre-written emails to clients, depending on certain trigger events that occur. 

Email autoresponders can be set up to act in certain ways, depending on the triggers. They can be triggered by customer actions, such as registration confirmations, inquiries, purchases, specific dates (you can automate an email to congratulate someone on their birthday, for example), cancellations or abandoned carts. Once the trigger action occurs, the software does the job for you and sends the designated automated response.

Key benefits of using autoresponder software

Answering each customer action individually would be too time-consuming and inefficient, so it will save you a lot of time. There are many other benefits, like the ability to:

• Reach customers with a relevant message at the right time.
• Drive engagement and stay connected with your clients.
• Follow up on orders or recover abandoned carts.
• Provide quick responses and increase trust in your brand.
• Free the employees to do other tasks.
• Welcome new users, thank current ones for their purchase or try to revert subscription cancellations.

Basically, email autoresponders are a powerful email marketing automation tool that enables you to increase customer trust, engagement, retention and sales.

How to choose the best autoresponder software?

Automation capabilities and workflow triggers

A good autoresponder should have automation capabilities along with a user-friendly interface. Check if the software has workflow templates, as it is easier to tweak rather than build them from scratch. 

The picture below illustrates a very intuitive automation system we have at Selzy.

That being said, you should also check how powerful and comprehensive the list of possible triggers on that software is: most of them offer simple things such as birthday, welcome and thank-you messages, but do they offer more complex automations, capable of reacting to other triggers? A lot of platforms gate their most powerful functions behind a paywall, so keep that in mind when choosing yours and stick to the best cost-benefit ratio.

Email deliverability and reliability

Bounced emails are one of the biggest enemies of email marketing, so make sure you choose a platform that has a good sender reputation. Your own sender reputation plays a part here, but selecting software that complies with all the data privacy regulations relevant to your business is key. You do not want to end up in a spam box because of automated responses, especially after ensuring you avoided that with your regular email marketing campaigns. 

Choosing the right software can also help prevent you from being blacklisted by your recipient’s email service provider. You can check an IP or domain reputation using ReturnPath’s Sender Score checker.

Ease of use and setup process

Part of the reason to use an email autoresponder is time optimization. Setting up an automation should not be rocket science, and the software you select needs to fit your needs, but also your skill level. You might find a platform with incredibly powerful functionalities – but can you set them up easily? How intuitive and simple to use is its interface? 

You have to choose something you are comfortable using and strike a balance between that and how well the automation capabilities can help you reach your goals. 

Integration with other marketing tools

Autoresponder software has to work in tandem with your other marketing tools. Other than a well-rounded automation kit, you also want a platform that gives you good analytics tools and template editors. 

Tracking systems are key, as you need to know if your automated responses were delivered. A/B testing will allow you to understand which version of your messages works best. 

Subscription forms, landing pages and other marketing tools should also seamlessly integrate with your autoresponder software. Your workflow will thank you if you use a platform that boasts all these features.

Pricing and scalability

There is freemium software, free software, and paid software. The point here is to weigh the benefits available against the price to be paid. There are advantages and disadvantages to using each type of software, so it is essential to know how the pricing system works before you fully commit. The goal is not to regret it later when your business outgrows the functions provided by your platform and unlocking them is too costly.

Depending on the business model, you may have to deal with many different versions, too, such as “Standard” or “Pro”, and license costs that differ between them. How much should it take to unlock function X or Y? Which versions of the software provide them and at what cost compared to the other options in the market?

Their latest update focuses on improvements to their template list, automation workflows and AI-powered features.

Their Free plan is very limited – you have email support for 30 days, 500 contacts and 1,000 emails per month, but none of the more powerful automation features. Paid plans start at $13 for the Essentials plan, billed monthly, for 500 contacts and 5,000 emails, plus access to a limited number of automated journeys, analytics and segmentation tools. The best value for money on the platform is found on the Standard plan at a monthly $20. The plan adds up to 200 automated journeys, more powerful analytics and segmentation tools, generative AI features and many email marketing staples, like A/B testing, landing pages and the like.

The pre-included automations also reflect that, with welcome emails, abandoned cart, back in stock warnings and purchase confirmation as its main headliners. The biggest advantage is that all features are unlocked, even with the free plans. What differs is the number of contacts and emails per month: the free plan offers up to 500 emails per month and 250 contacts. Paid plans start at $16/month and include 6,000 emails per month, but there are higher tiers and a custom plan too.

Kit – Best for content creators and bloggers

Kit is a marketing tool that focuses on bloggers and content creators. The user can create simple newsletter automations, welcoming emails and other email sequences with simplicity. The platform’s functionalities feature customizable landing pages (as seen in the example above), a tool for content monetization, audience segmentation capabilities and signup forms, among others.

Drip – Best for advanced segmentation & personalization

Drip is similar to Omnisend in its focus on e-commerce. The main difference is that Drip does not require you to connect an online store to it in order to use automation workflows. Drip’s strong suits are its email editor, segmentation and contact management, plus powerful real-time automation reports. It is also quite easy to use in comparison to how much you can do regarding segmentation and personalization.

Other features include over 20 automation templates, basic autoresponders and the possibility to customize and branch your automations.

Free vs. paid autoresponder software: Which one should you choose?

When to use a free autoresponder

To answer that question, ask yourself: what do I need from an autoresponder, and do I need to pay for that? Then, check your available options. In case the free plan suits your needs, by all means, use it. Free autoresponders are great if you are on a budget constraint, have other priorities or simply don’t need the more advanced functionalities in the current stage of your company’s life or growth. In case you are inexperienced – and that’s OK! –  they are also a great way of learning the workflow without any investment.

The limitations of free autoresponder tools

The main drawbacks of free autoresponder tools are feature limitations. Most of them allow you to do simple autoresponder tasks, but chances are, your business will outgrow the number of emails and contact list size that a free plan will accommodate. Consider them a good starting point, but eventually your campaigns will require more advanced automations, better data reports and a bigger array of functionalities that free tools simply can’t provide.

Why paid autoresponders are worth the investment

Regardless of your business type, there is a platform made for you. Whether you are an online retailer or a content creator, there are autoresponders built specifically to help you, and you should take advantage of that. Their best features, however, are often locked behind paid plans, but there are many benefits to it, including time-saving features that will also allow your company to perform better. 

Most of the paid plans have a price scaling, so you don’t have to pay the same price as an enterprise that is sending millions of messages a day. The investment it takes in comparison to the potential return makes it interesting to take the leap from free to paid, once you think your business is ready for it.

Final thoughts: Choosing the right email autoresponder for your needs

Now that you know the benefits of email autoresponders, the advantages and disadvantages of free vs. paid software and our top picks, you can make a well-informed decision. To summarize, take these into consideration:

• The current size of your business and your aspirations
• Your business needs

• Features and functionalities
• Your industry and market niche
• The goals of your current email marketing campaigns
