MailerSend has been extremely reliable and fast, with a more generous free tier and no hassle for my legitimate use of the software as a transactional system. Sendgrid required a lot of forms and pleading to use for my own clients.
Frank B. CEO
The ease of integration is super. I write predominantly in Golang for back-end services, and I had MailerSend integrated in about sixty seconds flat. I've moved to MailerSend for all transactional email services.
David G. Developer
MailerSend's free tier is amazing and allows us to prototype and start using the service without any concern about cost. Additionally, the interface is super clean and the integration was sooooo easy.
MailerSend gives us peace of mind. We never worry about our emails. All the work happens in the background—always addressing our needs.
