Resend Alternative MCP. Manage email delivery and domain setup from chat.

Listen up. This server gives your AI agent full control over everything related to transactional email infrastructure, right from your chat client or IDE. You manage sending emails, verifying domains, and handling API keys without ever leaving your coding environment. It's total email ops, period.

Sending Emails: Single Sends and Bulk Jobs

When you need to send a notification—whether it's one message or a hundred—you got options. Use send_email to fire off a single transactional email; you can specify the sender, the recipient(s), the subject line, attachments, and even set specific reply-to addresses. If you're announcing something big, send_batch_emails lets your agent send up to 100 emails simultaneously, though remember each one counts against your quota.

You can schedule these sends for later with send_email, or if things change, use update_email to reschedule an existing message by providing its ID and the new time in ISO 8601 format. If you scheduled something and then change your mind, don't sweat it; just run cancel_email using the message's unique ID.

Domain Health and Sending Authority

Deliverability is everything, so this tool lets you manage all your sending domains. You can register a brand-new domain with create_domain; when that runs, it hands you the necessary DNS records—SPF and DKIM—so you know exactly what to configure in your provider. To confirm that setup worked, run verify_domain using the domain's unique ID after you manually update your records.

You can check the status of all domains configured by running list_domains, which details their verification status and required DNS info. Need more detail on one specific domain? Just use get_domain with its ID to pull up full status and record data.

Auditing, Tracking, and API Control

You gotta know what's going out and who's sending it. Use list_emails to see a list of the most recent emails that went through, pulling IDs, sender/recipient details, subjects, and the last known event status for quick audits. For deep dives on one specific message, you can run get_email to fetch detailed information, telling you who it went to and if it bounced or triggered a complaint.

When it comes to credentials, you control access completely. You generate new API keys using create_api_key, specifying exactly what permissions the key needs—like 'sending' or 'domains.' To see all your current keys and their scopes without revealing the actual value, run list_api_keys. If a former employee leaves or you just need to kill access immediately, delete_api_key permanently revokes that credential using its ID.

You can also clean up domains entirely by running delete_domain, which deletes the domain and invalidates all associated DNS records—use that one careful.

This system makes your agent handle complex email operations—from initial sending to tracking bounces, managing credentials, and maintaining domain reputation—all in a single conversation.
