Then connect your app. Start with your sending identity. Ask Bird MCP to check the domain and its DNS records, then connect your application to the regional SMTP relay with an email-enabled API key. [Connect Bird MCP](/docs/ai/mcp-server) [Explore the Email API](/email-api) [SMTP configuration](/docs/guides/email/smtp) ## Change the connection. Keep the message. Add Bird’s host, port and credentials to your mail library or application. Keep your HTML and attachments. Set category, tracking and IP-pool defaults on the API key so each application sends with its own configuration. Use implicit TLS on port 465 or STARTTLS on 587 or 2525. Match the SMTP region to your API key. ## Your app sends it. Bird shows you what happened. SMTP messages appear in the same email log and reports as API sends. Keep the message ID from the queued response, then follow delivery, deferrals and bounces in Bird or through signed webhooks.

Use bird as the username and a regional API key with emails permission as the password. Connect to eu1.smtp.bird.com or us1.smtp.bird.com to match the key region. ### Which ports are supported? Use 465 for implicit TLS or 587 and 2525 for STARTTLS. Authentication requires encryption. Port 25 is not offered for submission. ### Can SMTP render a stored Bird template? SMTP takes content from the MIME message your application submits. Use the Email API when you want to send a stored template with structured parameters. ## Skalakan tanpa kehilangan kendali.
