Consider providing a list of issues that require their attention when they open the db. That is, the list is specific to them. They can then open the form to the item they choose from the list. You could also email that data in the notification email where you want to put this link. If there is a way to open a specific form filtered to the user by way of an email link I've never heard or read of it. I doubt it can be done.
The more we hear silence, the more we begin to think about our value in this universe.
Paraphrase of Professor Brian Cox.
