    1. Hi tom, We can’t find any support tickets under your email address. Since this is looks like a complicated issue, it would be best if you submit a support ticket.

  4. Sorry for the English, I use a translator.
    Tell me how to make sure that the mail that is sent from the site is not displayed or duplicated in my outgoing messages in the mail client. I don’t need her there. I use Outlook mail.

  5. Hi there,
    I have set up a “Gmail/Google Workspace” connection. Everything done as you describe in the YouTube video! No problems, no errors.

    But when I want to send your “Email Test” by clicking “send test email”, that little wheel is turning and turning, but NO test email is sent. Also, no other WordPress email is sent (for example when adding a new user). What can I do?
    Best Holger
