I’d find this feature very useful too. I work for a membership body and need to be able to re-send the account registration email en masse to large groups of contacts, not just on an individual contact basis. We’re due to launch our new Hubspot CRM/CMS soon and we’ll migrating existing member data from our outgoing CRM into Hubspot, so being able to resend the registration email would help us increase number of increased registration completions.
