Brevo smtp emails to other gmail accounts silently failing , verified domain to the rescue

odemailer with Brevo is an excellent combination for sending free emails (up to 300 per day) within your applications. However, a recent change implemented by Gmail and Yahoo has silently disrupted some functionality, preventing emails from reaching recipients.

To address this issue, Brevo recommends attaching a domain or subdomain to your account and verifying it. This verification process ensures compliance with the latest email sending requirements set forth by Gmail and Yahoo brevo help link.

Under Senders, Domains & Dedicated IPs
