“Very happy with MailerSend”
Support, service, and product quality are all excellent. Pricing is fair, and the team has been helpful from the start.
Kyle P., Owner & Educator, Small Business (G2.com)
“Clear website, excellent development tools”
A/B testing for transactional emails is rare, but MailerSend offers it. The Golang library worked well, and chat support was fast and competent.

“Features don’t matter if they’re taken away ”
I invested time into building with their features, only to have forced updates override my work. I no longer trust the platform’s stability.
Henry A., Product Engineer, Small Business (G2.com)
“Subscription doesn’t include what’s promised ”
After upgrading, I still couldn’t import contacts without buying extra credits. Refund request was denied. The UI is good, but the pricing model is misleading.
Matthias S., Small Business (G2.com)
“SMTP support resolved with patience”
Thanks to Mark and Ben for helping me understand the platform. They were thorough and patient with my SMTP query.
J.O. Spies, Verified Reviewer (Trustpilot)
“Documentation is clear and helpful”
I tested four providers—MailerSend stood out. Setup was easy thanks to their well-written documentation.
Rustam, Verified Reviewer (Trustpilot)

Our nonprofit was denied access without explanation. We expected more transparency and ethical handling from a company serving diverse causes.
