SMTP

Drop-in SMTP relay.

Point any app at smtp.xurel.co and authenticate with your API key.

HOST smtp.xurel.co
PORT 587
USER xrl_prd_xxx
PASS xrl_prd_xxx
TLS  STARTTLS


              host: smtp.xurel.co
port: 587 (STARTTLS)
username: apikey
password: xrl_prd_xxxxxxxx

If it speaks SMTP, it works with Xurel — frameworks, CRMs, legacy apps.

Username is apikey. Password is your Xurel API key. No extra SMTP credentials to manage.

SMTP traffic gets the same domain authentication, suppression, and tracking as the REST API.
