Hi @Ulrich Böhnke,

Thank you for reaching out!

There are a few factors that could impact the delivery of confirmation emails, such as the email domain is blocking Miro’s emails or the messages ending up in spam or junk folders. However, the quickest way to resolve this is to contact Miro support directly. I’d recommend reaching out to support, as they can investigate and assist further to ensure the emails are received.

Hope this helps!
