About MailerSend

MailerSend is a transactional email service from the team behind MailerLite. Developers connect it through a REST API, SDKs for languages such as Node.js, Python, PHP and Go, or a plain SMTP relay, then use it to send password resets, receipts, notifications and other automated email. Unlike some bare APIs, it also gives non-developers a drag-and-drop and rich-text template editor, so product or marketing staff can change email content without a deploy. Other features include inbound email routing, webhooks, suppression lists, email verification, DMARC and blocklist monitoring, and add-ons for SMS (US and Canada) and WhatsApp. There is a small free plan for testing and low volumes, then monthly plans priced by email volume, with overage billed per thousand emails and a discount for nonprofits. A two-week trial unlocks the top plan's features. It is a hosted service managed through a web dashboard; it suits startups and SaaS teams that want a modern email API with a friendly template editor.

Best for: SaaS and ecommerce teams who want an email API plus templates non-developers can edit.
