MailerSend, Inc. Reviews 

MailerSend is a service that I would highly recommend to other professionals in my field.
The service is comprehensive with its functionality, well documented, and support (automated and human) was prompt and second-to-none. Thankyou.

Biggest part of SaaS business is customer service. Mark from MailerSend shows great CS response.

He help me embark on trying MailerSend for evaluation purpose, and definitely move to paid plan soon.

Kudos!

Reviewed my first send, where MailerSend was concerned that I had some bad email addresses on my list. It was an error on my part, so they have now been removed. It's refreshing working with a team that both understands deliverability, speaks to you and listens, and helps rectify the issue instead of some bot or algorithm.

I had a great experience with MailerSend's support team, especially Glenn. Initially, my account wasn't approved due to a DNS misconfiguration on my end. Glenn provided very clear and professional assistance, and after I explained the situation, he manually re-evaluated and approved my account within minutes. The responsiveness and efficiency are top-notch. Highly recommended for any developer looking for reliable transactional email services!

Biggest waste of time. After investing months and money into a system I built to solely use Mailersend, now they are coming up with stupid requirements that have nothing to do with anything. Do you have legal grounds to contact the person? Wtf are you even on about. Anyway I wouldn't your time. Look for a better provider.

I had issues with my mail server sending unusual mails and i couldn't track it down , the guys in Mailsender were exceptionally helpful in finding the issue and helping me resolve the incorrect emails that were getting generated by my server. I'm very happy with the assistance and the service

Fast help, reliable

It does what its designed for.
No problems using the smtp relays and technical services. Support is super fast, there are warnings and hints regarding the reputation so you can react fast changes occurs in the smtp usage. Right now I'm using the free plan, since the last change the limits are a bit low but it's still fine.

MailerSend support has great service. First contact is by AI agent which is very user-friendly and clear where AI chat explain where the human service is rewquried.
In the second contact where the needs for the human service is specified, an answer is fast, short and clear what results in quick solving an issue

MailerSend is an excellent platform. The service is reliable, and their support team is incredibly fast and professional. They helped us resolve a technical IP configuration in no time. Highly recommended for anyone who values efficiency and great customer care!

We switched to MailerSend after having issues with our previous provider’s deliverability. Since the move, our transactional emails are hitting inboxes consistently. On the one occasion I needed to contact support, they were fast and actually helpful—not just canned responses. It’s a relief to have a service we can trust.

Cesar was very helpful and a great problem solver!
Managed to get my integration up and running very fast.

Fail ... unable to log in with a copy-paste code sent to an email. Life's too short to be dealing with incompetence

I’ve had a great experience using MailerSend. The platform is reliable, easy to use, and delivers exactly what it promises. The interface is clean and intuitive, which makes managing emails and integrations straightforward, even for more advanced use cases.

What really stands out is the quality of the service and support. Everything works smoothly, and whenever I needed guidance, the documentation and team were clear and helpful. MailerSend has become an essential part of my workflow, and it gives me confidence when sending transactional and automated emails.

I highly recommend MailerSend to anyone looking for a dependable, professional email solution.

I have to say that MailerSend support is exceptional and although they cannot fully see each client's setup, they ask all the right questions so that I simply have to provide the details accordingly.

Thank you MailerSend team, Cesar and Cyro for your professional assistance. May your platform continue to grow, while offering unsurpassed customer experience.

Great solution for my personal and business email. After having issues with our existing ISP and send mail services, these guys rock. Great platform and super fast technical help and response. Really easy to set up and even did the DNS updates for me.
