    Hi @yoibe1,

    Thanks for reaching out! Within the debug log you shared, I noticed the following message.

    We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.

    Could you please get in touch with your hosting/email support with the full error log, and they should be able to assist you accordingly.

    In the meantime, you may configure an alternative mailer on your WordPress site.

    I hope this helps. Thanks!
