When sending email, those contacts that do not have a matching email address (or if a contact record doesn't exist) is stored in the Attach to Act! Contacts Progress feature in the Not Attached Messages. My feature request is that the feature allow email multi-select and the Attach to Act! Contact option would not grey out, instead remain as an option.
I train users to check the Attach to Act! Contacts Progress once or twice a month (unless a quicker frequency is required in their environment). Once complaint is that several email messages may have been sent to a single individual and this process must be repeated for each unattached email. If the Attach to Act! Contact or the Attach to New Act! Contact was an option it would provide efficient handling of this area. See attached image.
