MailCraft vs Resend
Resend has earned a loyal developer following with a clean API, React Email templates, and a great local-dev experience. It's built primarily as a transactional email API — marketing campaigns, automations and contact management are newer, lighter additions rather than the core of the product.

Why teams switch from Resend
Get campaigns, automations and segmentation without bolting on a second product once you outgrow "just an API".
One contact database and one suppression list across transactional and marketing sends.
An MCP server that covers campaigns, automations and contacts — not just sending — with scoped keys deciding what an agent may do.
Email validation built into the same platform, instead of a separate service to wire up.
Switching takes an afternoon
Verify your domain, swap your send calls for the MailCraft API, and keep Resend running until the new domain is live.
