What our customers have to say

Clear interface

After messing around with Mailchimp and walking away unhappy, it's been a godsend to come across Mailersend. The layout is extremely clear, it hooks up to Zapier, and the one issue I had was cleared up by support in minutes. Most importantly, everything's landing in inboxes.

Ricky B.

Outstanding support

MailerSend is extremely easy to use and super fast to set up. I was able to send the first email via the API in minutes. With the predefined templates and drag & drop editor you're able to do a real quick start. What's really worth mentioning is the outstanding customer support which replies in minutes.

Tobias R.

Powerful API

Excellent deliverability, instant sending, powerful API, complete email analytics, fast support and a great dashboard. It's straightforward to set up; I barely used the documentation. Also, their KYC process is flawless and quick; I was able to use the full features only a couple of hours after signing up.
