SMTP

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

Creating an SMTP resource

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.

IP whitelisting

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

Private networking

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.

Accessing from tasks

You can send emails using your SMTP resource from tasks by using the email SDK. See Email SDK reference for more information.

Field reference

When this resource is attached to a task, its fields are available in the JSON environment variable AIRPLANE_RESOURCES under the alias it was attached with. For more information, see the SMTP field reference.
