    I haven’t had any issues with my website last week, but this week I’m getting this error for some reason and I can’t send e-mails.
    Does anyone know the solution? Thanks a lot!! ><

    Heads up! The last email your site attempted to send was unsuccessful.

    Email Source: WooCommerce
    Mailer: Other SMTP
