What do you like best about MailerSend?
Excellent deliverability, instant sending, powerful API, complete email analytics (opens, clicks, bounces) fast support
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. They have a great dashboard with a vast amount of valuable data about the emails sent, very well organized, and with powerful filter functions.
I contacted support once to ask for the availability of a feature (SMTP relay) and got a friendly answer within mere hours. They implemented SMTP relay a couple of days later.
The API is very fast to accept emails, and Sent-to-Inbox time is almost instantaneously, which is very important when sending password reset emails etc.
MailerSend's free tier is beyond generous, their regular pricing is very affordable.
I recommend trying them out if you are looking for a transactional email provider or transactional SMTP relay. Review collected by and hosted on G2.com.
