SMTP

The SMTP resource allows runbooks to send emails via SMTP. For a high-level introduction to resources, see the resources page.

To create a new SMTP resource, visit resources for your team, click the "new" button, and select the SMTP resource type. Enter your connection details in the form:

Name should be a human-readable name for your resource.

Hostname should be the IP address or DNS name of your SMTP server. Unless you're connecting to this server behind a self-hosted agent, this should be the public IP address or the public DNS name of your SMTP server.

If your SMTP server has restrictions on incoming network connections, you'll need to ensure the Airplane IP addresses are whitelisted:

• 34.121.89.145
• 34.68.100.27
• 34.72.182.225

To connect to an SMTP server inside a private VPC, you can self-host the agent and run the agent within your own VPC. Agents are responsible for sending emails, and will be able to connect to your SMTP server from within your network.

You can use your SMTP resource in runbooks by adding an email block.
