Why this helps
Tentative invitees can disappear from view while you focus on confirmed attendees and other work.
- Gather tentative invitees in a dedicated group.
- Make attendance follow-up easier to review.
- Avoid rechecking RSVP status manually.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and ActiveTrail once in the Notis portal.
- 2Create an automation by telling Notis the outcome you want, in the portal or from any channel.
- 3In one instruction, ask Notis to add an attendee to your existing tentative-RSVP group only when their status is tentative.
- 4Pick Attendee Response Changed as the trigger and choose where run reports should go.
- 5Test with one real tentative RSVP.
Questions about this workflow
Will accepted or declined invitees be added too?
The trigger includes accepted, declined, and tentative changes. Tell Notis to add the contact only when the current status is tentative.
Does this send an email to the invitee?
No. The selected ActiveTrail action adds a group member; it does not send a campaign.
What must already exist?
Create the ActiveTrail group you want to use for tentative invitees before testing.
