## Which one to choose

Mailjet's free plan sends more: 6,000 e-mails a month with at most 200 a day, against Resend's 3,000 a month and 100 a day, but it adds the Mailjet logo, and it also handles marketing mail and contact lists. Resend is the simpler API for transactional mail from your own domain. Both have an official MCP server.
