Our verdict
MailerSend is a developer-focused transactional email and SMS service from the MailerLite team, offering reliable delivery, a clean API, and competitive pricing for order confirmations, password resets, and automated notifications. Best for developers and SaaS apps. The main caveat is it's transactional-only — not for marketing campaigns (use MailerLite for that).
