Trigger
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
Action
Send Postcard
Tool to send a postcard via u.s. mail with specified recipient, sender, and front/back images. use after confirming recipient addresses and design urls. example: send postcard(to name='john doe', ..., front image='https://...', back image='https://...')
Why this helps
A cohort can be marked ready in a sheet, but the mailing still waits for someone to notice and act.
- Turn a status change into a clear mailing task.
- Reduce the gap between campaign preparation and delivery.
- Reuse an approved postcard design for the cohort.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Docupost once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name the campaign mailing.
- 3Tell Notis to send the approved postcard to the cohort represented by the changed range, using the supplied front and back image URLs and recipient addresses.
- 4Choose the Cell Range Values Changed trigger for the campaign status range, then choose a report channel.
- 5Test with one real cohort entry and verify recipient addresses and design URLs.
Questions about this workflow
What change starts the postcard workflow?
A value change in the specific A1 range selected for the Cell Range Values Changed trigger.
What postcard details must be available?
Each recipient's name and mailing address, sender details, and the front and back image URLs. Supply any missing values in the instruction or source data.
Can this workflow detect that a campaign is ready without a status field?
No. The chosen range must contain the readiness signal, and the instruction must explain what change means the postcard should be sent.
