WilboWhat happens when someone invites you
An invitation sent to your Wilbomail address forwards to your normal inbox with the event details and RSVP controls intact. Gmail can place the invitation on the Google Calendar connected to that inbox, where reminders and event updates work normally.
Ordinary invitation email is still carried by Wilbomail. The identity change happens only when control passes to Google Calendar for an RSVP.
What happens when you RSVP
Calendar RSVP is not an email reply through Wilbomail. Google Calendar creates and sends its own response under the signed-in Google identity. Wilbomail has no Google Calendar account or OAuth permission that could send that response as your alias.
In controlled Gmail testing, clicking Yes made the organizer see the real Gmail identity as a separate accepted attendee. The Wilbomail alias remained separately listed as awaiting a response. That result is the expected identity handoff, not a Wilbomail delivery defect.
Your two choices
Use the Calendar RSVP
Choose this for formal attendee tracking and the smoothest Calendar workflow. The organizer may see your signed-in Gmail address and treat it as the attendee who accepted.
Keep the alias as the only email identity
Do not click Yes, No, or Maybe. Open the forwarded invitation email and use normal Reply, leaving its recipient unchanged. Tell the organizer whether the time works. That message follows the ordinary Wilbomail reply route, though the organizer’s guest list will not show a formal acceptance from the alias.
There is currently no way to make Google Calendar formally accept as a Wilbomail alias. The choice is between Google’s formal RSVP under the Google identity and an ordinary Wilbomail email response under the alias.
