For people designing their own invitations, using the traditional “M” is completely optional. A simple “Name” or “Guest Name” line may be clearer and more convenient, particularly for modern celebrations where traditional formalities are less important.
When completing an RSVP card, guests should primarily follow the host’s instructions. They should clearly write the names of the invited guests, confirm whether they are attending, and answer any additional questions. If the invitation specifies a particular number of guests, only those invited should be included.
