Allow users to claim listing

If I want to send a business an email letting them know their listing has been listed on my directory, and invite them to “claim listing”, how do I do the following in V2:

1. what steps do I need to make sure listing is claimable?
2. what link do I provide them to allow them to claim listing?
3. what benefits does the business have if they update their listing, such as business hours, link to menu, specials/or deals? Does the deals add on work with V2?
4. eventually I would like to charge for featured listings, how do I accomplish this?

Many people will not claim unless they are tech savvy or it is very easy for them, so I want to make the benefits very clear to them.

thank you in advance!
