About MailerSend
MailerSend is a commercial service for sending application email, built by the team behind MailerLite. Developers send through an email API or SMTP relay, and the platform also offers an SMS API for supported countries and a newer WhatsApp API.
Beyond sending, it includes inbound email routing, webhooks, API logs, suppression list management, user management and an MCP server, together with tools for deliverability such as DMARC monitoring, blocklist monitoring and email verification. For creating messages it provides a drag-and-drop builder, an HTML builder, a rich-text editor, dynamic templates and split testing. MailerSend is hosted and offers a free sign-up.
