Automatic linking based on email address is not case-insensitive

When I link to contact databases through an automatic relationship based on their email address field, this linking should be case-insensitive because email addressess are case-insensitive. That is currently not yet the case, and automatic linking does not happen sometimes for that reason.

A workaround would be to have an automation convert email addresses to be lowercase, but it is more userfriendly that users do not have to discover this need.

because email addressess are case-insensitive

That’s not true per standards.
Yet of course most bigger public email providers treat them in a case-insensitive manner.
