Mail with Reply-To header not delivered

    Hey!

    Last night I debugged a client website and found out that, emails that contain a “Reply-To” header don’t get delivered by Brevo.

    The client website has a contact form that is setup to send E-Mails containing the message creators email address as a reply-to email on submit. This way the client receiving the message can comfortable reply with one click inside the email client.

    If I deactivate the transactional email of the brevo plugin the email is delivered.
    Also with the transactional email of the brevo activated I can see the email being send inside a SMTP logging plugin. The brevo log of the client don’t show the email. Therefore I guess the email is lost somewhere inside the sending service.

    Is the behavior intended?

    Greetings

    I had the same problem. I switched from using the Brevo plugin to using WP-SMTP configured to use Brevo as the SMTP service, and all emails worked ok after that.

    Hello there,

    Thank you for reaching out to us.

    The Reply-To header should not block the dispatch of emails.
    If the email is not showing in the transactional logs, the error is already caused on WordPress and/or the plugin generating/dispatching the mails.

    Please check, that only one property of Reply-To is passed when the mails are generated.
    Some plugin pass along the Reply-to header additional properties for reply to address, Which is not allowed in Brevo. For referents:
    { "headers": { "Reply-to": "Test name <[email protected]>" }, "replyTo": { "email": "[email protected]" }

    I would suggest you to open a ticket with the Brevo support, where you can also provide some references. The support team could check their internal SMTP logs and could provide the reason for the blocker easier.

    Best regards,
