Hello Syed.
1.Frisrt define your deeplink in deeplink configuration page.
2.Add your logic in deeplink Microflow like which page you want to show to user.
3.Link which you will send in email will become like this.
http://localhost:8080/link/NewCustomerInvite?InviteCode=xyz
4.Call Showhome page MF in your navigation, if request came from deep link then it will go into page written in deeplink MF else it will go into system default home page.
5.in your startup MF start deep link also.
using this approach, you can achieve your desire page.
