Why it matters
What it does and why it matters
Resend is an email API popular with developers for transactional email. Its official MCP server lets an assistant send single or batch emails, list and read sent and received emails, manage contacts, create and send broadcasts and verify sending domains.
For developers, it speeds up testing email features. For small teams, it can support simple broadcast emails with a person approving each send.
Because it can send email to real people, including broadcasts to whole lists, we use it with a restricted API key and require approval for anything beyond test addresses. Domain verification tools are useful when setting up sending, since correct DNS records are what keep email out of spam folders.

Security
Security considerations
-
Approve outgoing messages
Require a person to approve messages to customers until a workflow is proven.
-
Limit channels
Give access only to the channels, mailboxes or numbers a task needs.
-
Untrusted messages
Incoming messages can contain text meant to mislead an AI. Treat them as data.
-
Keep a log
Log every email sent, and keep broadcast sends behind approval.
