Honest take: Is MailerSend worth it?
MailerSend comes from the MailerLite team, which means it's built by people who understand email. They've created a solid transactional email service with clean APIs, email verification, and SMS capabilities. For many teams, it hits a good balance of features and simplicity. With nearly 200 Trustpilot reviews averaging excellent scores, users consistently praise the support quality and platform reliability—a clear inheritance from MailerLite's reputation for customer service. The main reasons people look elsewhere are the lack of marketing features and the desire for either a more modern developer experience or a unified platform that handles both transactional and marketing email.
But there are reasons to look elsewhere:
If you want better DX: Resend
Resend has the best developer experience in email. React Email for templates, modern SDKs, clean API design. If developer experience matters more than MailerSend's email verification, Resend is the choice. See our Resend comparison.
If you need marketing too: Sequenzy
MailerSend is transactional-focused. If you need marketing campaigns, you'll need a second tool. Sequenzy combines both with AI content generation. One platform, one bill, no syncing subscriber data between tools. Read our SaaS email marketing guide for more options.
If deliverability is critical: Postmark
Postmark achieves exceptional deliverability through strict customer vetting. They reject questionable use cases to keep IP reputation clean. If your password resets and 2FA codes must arrive instantly, Postmark's focus matters. Check our email deliverability glossary for more context.
If cost is everything: Amazon SES
At $0.10 per 1,000 emails, nothing beats SES on price at scale. But you're on your own—no templates, no dashboard, no deliverability help. Only choose this if you have engineering resources.
If you want open-source: Plunk or Mailcoach
For teams who want full control, open-source options like Plunk (simple transactional) and Mailcoach (provider-agnostic management) let you self-host and eliminate vendor dependency entirely.
If you need multi-channel notifications: Knock
When your needs go beyond email and SMS into push, in-app, and Slack notifications, Knock provides a unified notification API that replaces multiple tools including MailerSend.
