@Erwin Duisdeiker - I just tested this and my confirmation email came within seconds (I am using Gmail). However, email can involve many hops through outgoing/incoming servers, spam firewalls, etc. The problem could exist in many locations. I would suggest that the user reaches out to Miro support via this special form and perhaps they can at least confirm that the email was sent on their end.

@Robert Johnson 

Thanks for reaching out and testing it yourself. I was already in the process of contacting Miro support. But thought to check it first in the community.

So thanks again and I will proceed with my miro support request.

kind regards

Erwin
