How many functions should your invitation list?

A common instinct is to put only the Baraat and Walima on the card and mention the Mehndi 'to the close ones'. That works right up to the moment a cousin asks in the family group what time the Mehndi is, and then forty people know there is a Mehndi and are wondering whether they are invited.

List everything you are holding

Dholki, Mayun, Mehndi, Nikkah, Baraat, Walima, a Qawwali night, a family dinner: add each one with its own date, time and venue. Name them what your family calls them; the card does not care whether it is a Mehndi or a Sangeet.

Then decide who sees which

This is what private guest links are for. Each guest is ticked for the functions they are invited to and sees only those. Somebody invited to the Walima alone opens a card that looks like a Walima invitation. The close family sees the whole week. Nobody has to wonder, and nobody has to be told 'that one is just for family'.

Put the main day on the countdown

The countdown on the card points at one event. For most weddings that is the Baraat; for a Nikkah-only celebration it is the Nikkah. Pick the day guests are most likely to plan travel around.

Timings can be honest

'7:00 PM onwards' and '4:00 PM sharp' are both fine, and it helps guests to know which is which. A Nikkah at a masjid has a real start time. A Mehndi does not.

You can add a function later, too. Nothing has to be final before the first link goes out.
