Drupal 7, CiviCRM 5.10
I'd like to send out an "update details" email to contacts - a profile with checksum. It will include some other custom field questions but i want to be alerted specifically if the general contact fields are updated - Address, phone number etc.
I can put those who completed the profile into a group but that won't distinguish between those changed and those whose contact details remain the same..
I don't think i can create a duplicate to dedupe later if using checksum?
The only other idea i had is to have two profiles - one for my custom field questions and another for "change contact details" and rely on contacts only submitting that form if things have been altered - Even then it would be useful to know which field specifically had changed but perhaps that's my only option?
