What is MailerSend?
MailerSend is a transactional email and SMS service from the team behind MailerLite, designed so both developers and non-technical teammates can work with sending. Developers integrate through a REST API, SMTP relay, and official SDKs, while designers and support staff manage templates with a drag-and-drop builder — no deploy needed to tweak an email. The platform covers the production essentials: inbound email routing, webhooks, suppression management, dedicated IPs, and analytics on deliveries, opens, and clicks. Built on infrastructure refined over a decade of email sending, MailerSend emphasizes deliverability and offers verified domains with SPF, DKIM, and DMARC guidance. A free tier of 3,000 emails per month and volume-based pricing make it a popular, cost-effective alternative to SendGrid and a frequent comparison point with Resend.
