Mailersend is a transactional email and SMS platform founded in 2020 by the team behind MailerLite, headquartered in Vilnius, Lithuania, that provides developers and product teams with a developer-first infrastructure for sending application-generated transactional emails and SMS messages. Built as a distinct product from MailerLite's marketing email service, Mailersend was designed from the ground up to address the transactional sending use case with an API architecture and feature set oriented toward developer workflows — providing a clean REST API with comprehensive SDK support, an SMTP relay option for existing codebases, webhook-based event notifications for delivery tracking integration, and a no-code email template builder that allows designers and product managers to own template updates without requiring developer involvement for each change.
