How is an e-invitation better than a picture I forward?
A picture answers nothing. A page carries the ceremony time, the venue, the evening after, directions, and a reply button, and it stays correct if any of that moves. Guests find their own answers instead of messaging you.
Can I cover both the ceremony and the party on one link?
Yes, and that is the usual graduation case. Give the ceremony and the evening their own sections with their own times and venues, plus one line on the travel between them, so guests see the whole day in order.
What happens if the ceremony time changes after I send it?
You edit the time on the page once, and every guest who opens the link afterward reads the corrected version. No reprint, no separate message explaining the change โ which is precisely where graduations need it, since universities confirm times late.
Do my guests need an account or an app to reply?
No. They open the link on their phone, read the invitation, and tap to confirm in a couple of taps. Nothing to install, and no sign-up standing between a yes and your list.
How do plus-ones and dietary notes work on an e-invite?
You set whether guests may name a companion, within a limit you decide, and offer meal options if the evening is a sit-down meal. Each answer is recorded with their reply, so you read the full picture rather than chasing details.
