Why this helps
A campaign can keep inviting prospects to times that have already filled, creating avoidable follow-up and confusion.
- Check free and busy availability before a campaign promotes slots.
- Reduce manual calendar checks and follow-up.
- Use returned availability without exposing event details.
Setup
Build it in a few focused steps.
- 1Connect ActiveTrail and Cal once in the Notis portal.
- 2Create an automation named for checking campaign meeting availability.
- 3Tell Notis to check the specified Cal calendar and summarize whether the requested time range has availability before a campaign shares meeting times.
- 4Choose the webhook trigger and where run reports should go.
- 5Test with one real campaign time range and calendar.
