    Hi there @cw1210,

    Thanks for reaching out! According to the error message, the SMTP server you’re connecting to is rejecting the email because it thinks it contains spam content. Basically, your email is triggering their spam filters, and they are refusing to send it. You could try contacting your SMTP provider about it to find out what rule you might be triggering. It may be a getting misflagged, or there may be part of your email that needs to be changed.

    Additionally, you can try sending through another mailer service. Check out this guide in our documentation. It walks through each mailer we support and includes the benefits of each: https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/

    I hope that helps! Have a great day!
