    Hi @anithecoolboy,

    Thanks for reaching out! Within the error you shared, I noticed the following messages:

    We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.
    This message was classified as SPAM and may not be delivered

    Please note that this error message is returned by your email provider. I recommend contacting their support team with the full error message for further assistance.

    In the meantime, I suggest configuring an alternative mailer on your site. You can view all available mailers here.

    I hope this helps!
