Bring launch news to the mailbox
Give your most engaged waitlist members a physical launch announcement when the product and mailing details are ready.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send Letter
Tool to send a letter via u.s. mail with specified recipient, sender, and pdf. use after confirming recipient and document details. example: send letter(to name='john doe', to address='123 main st, ...', file url='https://...')
Why this helps
Launch follow-up can become another unowned list when marketing plans, contact cleanup, and fulfillment happen in different places.
- Tie the mailing to an explicit launch approval.
- Prioritize verified waitlist contacts with complete addresses.
- Keep the ready-to-mail announcement from becoming a separate tracking project.
Setup
Build it in a few focused steps.
- 1Connect Emailable and Docupost to Notis once in the portal.
- 2Create a webhook automation via Automations or ask Notis to build it in plain language.
- 3In one prompt, ask Notis to mail the approved launch PDF only when the webhook confirms launch approval and the waitlist member passes Emailable validation with confirmed address and sender.
- 4Select the incoming webhook trigger and report channel; test using one approved launch contact.
Questions about this workflow
Will every waitlist member be mailed?
Define the eligible segment in your prompt and require an approved launch signal, passing email check, and complete postal details.
Can this send before the product is available?
Require the explicit launch approval or release-ready signal in the webhook before Notis sends.
