Send an email​

  1. Add an SMTP resource and configure its host, port, security mode, and credentials.
  2. Add Send Email to the workflow and select the SMTP resource.
  3. Map recipients, subject, and body.
  4. Add attachments only when required and verify their content type and size.
  5. Test delivery from Development before promoting the workflow.

Receive email​

  1. Add an IMAP resource and configure the mailbox connection.
  2. Add Email Receiver as the workflow's event source.
  3. Select the mailbox folder and polling behavior.
  4. Map message headers, body, and attachments to downstream activities.
  5. Define how successfully processed messages are marked or moved so polling does not create duplicates.

Security and reliability​

  • Store mailbox credentials in the configured resource; do not hard-code them in workflow mappings.
  • Use TLS and validate the server certificate.
  • Avoid logging message bodies or attachments that may contain sensitive information.
  • Design receiver workflows for duplicate delivery and partial attachment failures.
  • Apply recipient allowlists when workflow input can influence outbound addresses.
