What Mailgun is
Mailgun is a developer-focused email API for sending, receiving and tracking mail at volume. Inbound routing and detailed logs make it a good fit when email is a data source and not just an output. The interface assumes a developer; marketing teams will not be composing anything here. Logs are the reason support tickets get resolved quickly.
What Resend is
Resend is a transactional email API aimed at developers, with a clean SDK and React-based email templates. It is built for the case where email is part of the product: sending is an API call, and templates are components rather than a drag-and-drop editor. That makes it a poor fit for marketing teams who need to compose campaigns without a developer.
