AISend

AISend lets Claude send email from your own domain through your AISend account, and check what happened to it. What you can do: 1. Send an email you and Claude wrote together, from an address on a domain you verified in AISend. Your assistant asks for your approval before sending in clients that confirm tool calls (this is the client's setting, not enforced by AISend); sending is real and cannot be recalled. 2. Check delivery: was an email delivered, bounced, opened or clicked. 3. Look through recent emails by status, recipient or subject. 4. Validate an address (format, MX records, disposable and role addresses) before you send to it. 5. See which sending domains are verified and which API keys exist. Requires an AISend account (aisend.app). You sign in and approve the connection on aisend.app; Claude never sees your password. The connection is an API key named "MCP OAuth: Claude" that you can revoke at any time on the API Keys page. Every send goes through the same limits and checks as AISend's API: a verified sending domain, your account's sending limits, the suppression list and abuse protection. Before a domain is verified you can only send a test email to your own account address. AISend is for mail your recipients expect, such as notifications, receipts and replies; do not use it for purchased lists or unsolicited bulk mail.
