Why don't I receive the email containing the code with certain email addresses?

The module sends emails uniformly, regardless of the address entered.

Therefore, if some messages do not arrive, it likely does not come from the module but rather from an external factor.

Several causes can explain this situation:

Sender address is the same as the recipient address:

If you use the same address to send and receive emails, your mail box often considers this message as suspicious and automatically filters it.

Unsuitable sending method:

Classic SMTP services (Gmail, OVH, etc.) or PHP's mail() function are not designed to guarantee good deliverability of transactional emails.

For reliable sending (such as order confirmations or emails generated by our module), we recommend using a dedicated service such as Brevo, Mailjet, SendGrid, or equivalent.

These specialized services ensure better deliverability and faster sending of all transactional emails from your store.
