By Impran M N
Broken contact forms, delayed order confirmations, or password reset emails landing in spam usually trace back to a poorly configured mail relay. Brevo's SMTP service provides a free way to route transactional email through a reliable cloud relay with proper domain authentication. This guide covers finding your credentials and generating a secure key.
01Locate your master SMTP parameters
Open your workspace panels to uncover the host name, active user login, and available port values needed to configure your SMTP relay.
02Generate a secure SMTP key
Create a unique, dedicated SMTP key rather than reusing your main account password, keeping your credentials isolated per integration.
03Enter the settings into your website or app
Plug the host, port, username, and generated key into your website's contact form plugin or application's mail configuration.
04Complete DNS authentication
Handle the DNS zone handshake authentication for your domain to improve deliverability of transactional messages.
05Run a live delivery test
Send a test transactional message through your configured SMTP relay to confirm it delivers correctly before relying on it in production.
