  description: MailerSend's REST API provides endpoints for sending transactional and bulk emails, retrieving message activity, and managing templates, domains, sender identities, scheduled messages, and webhooks. Authentication uses a Bearer API token. Single email sends are asynchronous and return an `x-message-id` response header.
