# SMTP profiles

> Configure and validate SMTP delivery profiles for Complete campaigns.

SMTP profiles define delivery transport and sender identity for Complete
campaigns.

## Transport settings

Configure the SMTP host, port, username, password, sender address, and optional
sender name. Select at most one encrypted transport mode:

* **TLS** for STARTTLS;
* **SSL** for implicit TLS;
* neither only when the approved test server explicitly uses plaintext.

For new profiles, **Test connection after creating** is enabled by default and
can be turned off before saving. Profile updates are tested by the backend
before they are committed; a failed test rejects the update instead of saving
unusable settings. You can also run a connection test from the profile list.

## Ignore certificate errors

Keep **Ignore certificate errors** disabled. Enable it only for an explicitly
approved test server using a self-signed or otherwise unverifiable
certificate. It is valid only when TLS or SSL is enabled and weakens endpoint
authentication.

## Sensitive values

SMTP passwords and DKIM private keys are encrypted before persistence. They
remain sensitive: restrict dashboard access, avoid screenshots containing
them, and rotate them after the engagement.
