Also great email automation sequences and low learning curve. Cons Somewhat pricey on higher tiers. Starts getting expensive if your email list becomes too big. Wish there were more pricing options. Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Was getting too expensive on Mailchimp, had to switch. Review Source MC MIRIAM C. Coach Professional Training & Coaching Used the software for: Less than 6 months ### "An easy to use platform with lots of features even with the free version" March 28, 2026 5.0 I've used Mailerlite to send my professional newsletter. I have the free version, which already offers many features. Pros What I like most is how easy it is to use, and if you're looking for instructions on how to do something specific, it's very easy to find the answer in the Help Center. Everything is explained very clearly. Cons I really can't find anything I don't like about Mailer Lite. In my first campaign, I realized that many of my subscribers were getting my emails in their spam folders, but Mailerlite has a well-explained article on how to prevent this. I followed the instructions for my next campaign, and it worked very well. Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) The free version has more features, and I found it was easier to use Mailer Lite Review Source VR Verified Reviewer Engineer Computer Software Used the software for: 6-12 months ### "Would not recommend" November 27, 2025 1.0 Not good. Stay away from this company unless you do not care about your transactional emails delivery. Pros UI is nice although sometimes it is buggy. Used to offer a generous plan with no monthly fee (no longer) Supports responds quickly but it is not flexible. Cons Their spam review process is completely terrible. I received ONE spam complaint (from thousands of emails being sent for over half a year) and account was suspended within a few days when I was on holiday and had limited access to computer, which prevented customer emails from being sent. To reactivate email sending, their requirement was to add a recaptcha and email verifications using their add-on service, which is somewhat reasonable but obviously takes time to do. They did not enable email sending until the latter was implemented. They changed their free plan (Hobby) to $7/mo forcing users to pay a monthly fee instead of just overage and the Free plan is a joke now. Review Source Response from MailerLite December 10, 2025 Hi there, we’re sorry to hear about your experience. After reviewing your account, the suspension wasn’t triggered by a single complaint; our system detected multiple spam complaints over a short period, which brought the account above the acceptable threshold. To protect deliverability for all MailerSend users, sending is automatically paused when this happens. Our team outlined the steps needed to reactivate sending, including adding reCAPTCHA and setting up email verification to prevent further issues. These measures are standard for accounts experiencing complaint spikes and are required before sending can resume. We understand how frustrating this can feel, especially when timing is difficult, and we genuinely tried to help get things back on track as quickly as possible. If you’d like to revisit the setup or review the requirements again, our team would be happy to help! Rodrigo S. CTMO Marketing and Advertising Used the software for: Less than 6 months ### "Worth every penny" October 29, 2022 5.0 We haven't been able to really on email before using MailerSend. We were always worried that the email would go to spam or promotion, but now our clients sometimes say "how did your FIRST email got into my inbox with a star on it?".For us, email is critical for the businesses that we help and MailerSend has been playing a critical role. Better still, they have humans that respond and read what you write to them when you need. This is extremely important. Pros It has a strictly anti-spam police and this benefits those that use email as a tool to deliver messages that the client wants to see. Cons I have tested a lot of softwares on the market, the only thing about MailerSend is it's pricing, but overall it can double our open rate which in turns makes it even cheaper that every other tool. Alternatives considered [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/)[Elastic Email](https://www.capterra.com/p/148326/Elastic-Email/)[SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing MailerSend At first, I tested their quality of service (SMTP) and it was greater than everything I have seen and tested. And gosh, I tested a lot. But their support and easy to use interface was glorious. Switched from [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/) We never do spam and always try to send only emails that our clients asked for. Yet, I was tired of being punished and losing accounts of clients on Amazon SES and they just say "you have something wrong but we won't tell you. Fix it but we won't respond you". MailerSend told me when something wrong, blocked my account and, uppon my response, they unblocked in 10 minutes (because I always follow the rules). Despite the numbers and algorithms telling something, a real human has unblocked account because he could understand what happened (and it was not my fault). In Amazon, my clients lost their accounts in the most critical moments. Review Source Dimitri L. President Internet Used the software for: 1-2 years ### "Perfect to set a tech startup on fire" June 15, 2023 5.0 MailerSend, coupled with Heroku, is an easy and strong way to serve e-mails serverless. Pros MailerSend is a reliable and performant service to serve mails to our users, anytime and from everywhere. Cons I really have nothing bad to say about MailerSend. Switched from [Mailgun](https://www.capterra.com/p/159630/Mailgun/) Mailgun decided to severely restrict our company, which was paying them a subscription. Review Source KL Kara L. Founder Consumer Services Used the software for: I used a free trial ### "Use SendGrid instead. Terrible customer service." August 2, 2024 1.0 Terrible. When you've only used a software for less than an hour and get essentially banned from it while you're just trying to set up your account, it's not a good experience. Pros Nothing. I never got to use it because they rejected my account, and when I asked if they could provide a list of things I needed to fix, they just repeated that they could not approve my account. Cons That I couldn't even use it? I wouldn't be so upset if I could have just given any useful information to correct whatever was wrong. They say they perform a thorough check to determine the account's "validity." But they can't tell me where I failed the checks? And because I failed their criteria, my whole account is invalid?? What does that even mean or imply?? Their vetting process may be for a good purpose, but it is treating legitimate, genuine business owners like we're scam artists or something. It's like they're assuming you're guilty until proved innocent instead of the other way around, except you don't even know what crime you're being accused of and you have to prove you didn't do it. I've got major beef with their customer support just from the one interaction I had. I'm not even convinced a person (vs AI) responded to me. It was so unsympathetic that it might as well be a robot. No, I take that back. ChatGPT is much more sympathetic than whoever replied to me. Alternatives considered [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing MailerSend Because I already used MailerLite and thought it would be an easy transition. Boy was I wrong. I'll be using SendGrid instead. Review Source David S. Director of Installation Construction Used the software for: Less than 6 months ### "Best entry-level transactional email provider" June 28, 2021 5.0 I set it up in one day. I had a delay because I'm using Cloudflare and forgot to set my DNS records to "only dns" to bypass their proxy. As soon as I did it, my account was active and ready to be tested. After sending 20-30 emails I applied the "upgrade" for the Free plan, and that was it. It's been working with great deliverability rates since. Pros The free tier is very generous at 12k emails/month, perpetually. Which makes it perfect for a small size e-commerce or growing online community. Since it has a pay-as-you-go model, you can use it even for higher # of emails without having to commit to higher monthly fees elsewhere (specially for volumes that will go unused). Cons So far, I haven't seen any on the technical side. On the cost side, after 20k emails/month it would make more sense to move to a different provider, I wish they could review this, as is not ideal to jump from provider to provider as one scales. It would be preferable to just stay under MailerSend, maintaining the economical benefit. Alternatives considered [Mailjet](https://www.capterra.com/p/130105/Mailjet/) Reason for choosing MailerSend The free tier has everything i needed from the paid plan at MailJet at my email volume requirements. Review Source Response from MailerLite July 1, 2021 Hi David, thank you for writing down your experience with us - we truly appreciate it. We're also glad to hear some of your feedback regarding our users scaling with us. Something I will pass down to make sure this is kept in mind.

I was able to use MailerSend in a project once; however, the two other projects where I recommended MailerSend received very bad treatment. The account was denied approval for no sensible reason, and one of them even got suspended. This is after effort had gone into integration with the applications being built. I have gone back to Postmark for my peace of mind Pros \- The UI is easy to understand. - The setup was a bit quick Cons \- Bad customer service. - Unclear documentation of APIs.

July 9, 2021 5.0 Pros Great documentation, I found it easy to set up my workflow using Node. Cons I don’t know anything that’s missing to be honest. Alternatives considered [SendGrid](https://www.capterra.com/p/204113/SendGrid/) Reason for choosing MailerSend I can use it for free. Switched from [Netlify](https://www.capterra.com/p/154989/Netlify/) The Netlify forms were somewhat limiting. No templates, no control over Askimet spam functions.

COO Child Day Care Services Used the software for: Less than 6 months ### "STAY AWAY FROM THIS COMPANY!!!" February 3, 2025 1.0 Pros There is nothing to like, this is the worst company ever! Cons STAY AWAY FROM THIS COMPANY!!! It’s impossibly hard to use without any support or resources. This is waste of time and funds i have amazing skills for email management and marketing but this was the worst system ever and i wasn’t able to use it. They have horrible product and even horrible customer service which is never helpful. I canceled without being able to use their service and paid for standard plan but never got to use it. Wasted my time and nerves and there is no refunds whatsoever. If there is one company i definitely hate its this one. Save yourself and stay away! They don’t care and want to scam people into buying their shitty products . Review Source Response from MailerLite February 5, 2025 Thank you for sharing your experience, Liana. We’re sorry to hear that MailerSend wasn’t the right fit for you. Our team works hard to provide a powerful yet accessible platform with helpful resources, and we appreciate your feedback.

Implementation is challenging. Pros Technical email marketing to the max. Best one out there. Great for system emails and situations where you want to really lower the bounce rate. Cons Will be necessary to use a developer, so it is possible that it will take longer to setup. Review Source Response from MailerLite March 24, 2025 Love hearing this, Daniel! 😊 Optimizing email sendings and reducing bounce rates is what we’re all about, so we’re glad MailerSend is working well for you.

Tried it for a month and changed to a yearly plan after about ten days. Pros Mailersend is so simple. Everybody can use it. And it's way better than Amazon. I'm so happy I've found it. And Service is really great: fast and calm! Cons If I have to say something: The stats could be longer than two weeks. Switched from [Amazon SES](https://www.capterra.com/p/179662/Amazon-SES/) Amazon has a big spam issue. Review Source ET Evelyn T. Admin Arts and Crafts Used the software for: 1-2 years ### "Mailersend Review" April 22, 2024 5.0 Pros Easy to set up and has been pretty reliable! If any mistakes are made on the site end they're quick to restore your account after proof fixes have been made have been shown and customer service was very fast. Cons The way multiple account types are handled and the two different registration/login portals are done can be confusing or cause you to accidentally get locked out of an initial account if you registered two "main" ones mistakenly to the same email, seems to be an oversight that'll hopefully be fixed/prevented in the future!

October 24, 2021 5.0 Pros The customer support was just great. \[SENSITIVE CONTENT\] from the support team is amazing. I got a response in minutes with so much information. I am not very experienced but I was able to set up all the emails I need for my website. Cons Every time I open the web interface I have to login to my account, but maybe its because of my browser. And its not a problem for me.

Pros The easy use of the api with react / next js, the feature templates with the option to use variables in the templates. Cons THE FREE TIER The client installation with npm, the friendly dashboard and the support team Reason for choosing MailerSend because the free tier, and the email templates feature Review Source HA Harry A.

Pros Great value for money, and does what it should. Support is insanely quick and very helpful and polite. Cons Took a little while to get verified, but it's normal with SMTP to have to fiddle with it a bit before it works perfectly. Reason for choosing MailerSend Many were expensive or made you pay for even a small number of emails. Review Source TC Tim C. IT Solutions Implementation Information Technology and Services Used the software for: Less than 6 months ### "great tool" December 28, 2021 5.0 very positive. Mailersend is used to assist outbound notification messages from a web app to subscribed users on daily basis and 'it just works' Pros mailersend does what was needed - SMTP outbound service that was easy to setup, easy to monitor, and works well.

I would definitely love to connect with the team to stay in touch. Thank you good luck for the future. Pros Although the platform is very great, I like the live customer support feature. The team is very active and replies very quickly if someone is facing difficulties in building some templates. This helps in the learning of the user also. Thanks to this amazing platform.

Wordpress Creator Internet Used the software for: I used a free trial ### "Avoid using unethical companies that behave in an autocratic way. We need to stand up to this mistreatment." March 2, 2024 1.0 Mailersend just refused any discussion about why our recently created account was shut down and not approved from the start. I am representing a small organization that is behind one of the most famous City Marathons in our country, which already has a 5 year experience behind. I am creating their new website. This cold, unjustified refusal is humiliating and incomprehensible and we feel mistreated in a way that never happened to us before. And again, running an organization with such a serious and noble cause, like promoting health and team spirit, where people from different backgrounds come together, we thought that at least we deserve an explanation for being refused. So at least we could improve in the future or understand where we went wrong. But they didn't even have the nerve to share that. If your excuse is "It is our right to refuse any client without justification" then this autocratic way of running a company has no ethical reasoning behind it. Sure, it is your choice and oyu have the right to do that, but it will surely cost you a lot in future. Running a business in an unethical way always costs a lot in the long run. This refusal sends a lot of doubt: were we refused for some wrong doing, or are you just discriminating because of where we come from? Is it because of something we did or didn't do, or you just don't like us? I hope everybody will be able to read this before making the right decision, because it is one thing to run a "successful" or "good" company, but it is another thing to run an ethical company with principles. Also, they made us lose valuable time in back and forth exchanges, only to just kick us out even before we try it out. In the other companies, even competitor companies, we are at least given a chance, but here, they are saying that we don't deserve a chance. What kind of reasoning is that? It is beyond words. Pros Nothing, I didn't even get a chance to use it. Cons The fact that they don't justify why they refused us their service. I would accept being refused if I did something wrong. It would at least help us to improve the next time. But being shut down without any justification? Totally unacceptable. Switched from [SMTP2GO](https://www.capterra.com/p/166646/SMTP2GO/)[SendGrid](https://www.capterra.com/p/204113/SendGrid/) I like a lot mailersend's offer, it would have offered us a smooth transition from free to paid plan as we are growing. I love sendgrid and smtp2go, but because the company I am creating the website for is still small, I believed that mailersend is a much better match for their use case. I was wrong. Review Source FH Ficht H. CTO Real Estate Used the software for: Less than 6 months ### "One of our better decisions to switch from a large provider (probably the largest) to MailerSend!" August 11, 2022 5.0 Very positive, and the point i would like to stress the most is the fabolous MailerSend support. We where so disappointed with our prior mail providers support that this experience which we had with MailerSend support was a blessing from the start on. Short response times and really tech savy & competent support contacts (thanks Abdullah and the others!). This is for sure the major benefit of switching to the MailerSend. Pros For us deliverability and reliability was the most important factors. MailerSend made it their mission to send reliable transaction emails, this specific focus was what got us as most others have their focus on newsletter (mass sending but not reliable). MailerSend's software has all the features we needed and which we where already using with our prior provider. The API is well documented and thoughtfully implemented, the deliverability was good from the start. Really really glad it went smooth as it did so far! Cons It is a minor drawback, and to be fair only a drawback because MailerSend provides an additional feature compared to others to start with. The feature is retrieving the content of sent template emails, the drawback is that those emails are not parsed. So we had to implement our own parsing which in some way nullified the advantage of parsing content from MailerSend. Reason for choosing MailerSend Focus on transaction emails Switched from [Brevo](https://www.capterra.com/p/132996/brevo/) Terrible customer support, unreliable service, features which didn't work and general lack of understanding of our needs. Review Source RP Ruth P. Founder E-Learning Used the software for: 2+ years ### "Affordable version of Mailchimp with faultless customer service." February 2, 2023 5.0 I've used Mailerlite for 5+ years and there have been more than happy with the service. Failed emails is upsetting when you have a large sales campaign that is time-sensitive, but every time the customer service staff are eager to help, timely responses and so nice that it soothes me!I have a hefty web of automation working with Zapier and that integration has been nothing but smooth - great segmentation and customer management. Pros Ease of use & automation features - I use an older version of Mailerlite that encompasses landing pages, automation and email campaigns & analytics in one. I've used it for 5+ years and the best thing about this software is the customer service. Cons At times there are snags in the system, but whenever I've had a failed campaign (maybe 2-3 times a year) the customer service team have been on it immediately and super helpful and polite. Sometimes the rich-text editor can be buggy - but it's my preferred template so I have workarounds for those bugs (like writing in a separate doc and copy pasting text over to avoid over-deleting of content). Switched from [Mailchimp](https://www.capterra.com/p/110228/MailChimp/) Mailchimp was too expensive. Review Source KG Kenneth G. Executive Director Non-Profit Organization Management Used the software for: Less than 6 months ### "Read this Review" August 21, 2023 1.0 Pros Intuitive interface. Custom unsubscribe is helpful. Cons Stay away from mailersend at all costs. Mailersend is a 'HASSLE-FOCUSED' company. They use their terms of service to manipulate customers into using their platform but when their platform sends 100% of your test emails to spam (or missing) and you know you've configured your DNS properly and have a reputable domain to send from, they don't care about that or when you request a refund for really bad service and results. It's a scam with empoyees forced to flaunt that it's a great place to work all over their website (what other companies do that??) when the leadership team is probably dysfunctional and isolated. If you don't believe me sign up to their platform and send test emails using a reputable warm up platform. (not using glock apps because companies like mailersend know how to get good scores using that app) You'll see that all or almost all of your emails from the warm up process are going to spam or missing. THAT'S A MAJOR RED FLAG. People who have given mailersend rave reviews have clearly not really tested the platform. That probably explains why mailersend is one of the few platforms that cannot deliver what they claim they can. I would recommend a 'terms of internal practice' review for mailersend and maybe even dump Ignas. It might be time for a major shakeup. Review Source Similar Products Featured
