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

Invoice follow-ups are easy to postpone when they require finding a document and re-entering an address.

  • Reduce the steps between deciding to follow up and sending a notice.
  • Require an approved notice PDF and confirmed postal details.
  • Keep sensitive billing correspondence deliberate and reviewable.

Setup

Build it in a few focused steps.

  • 1Connect Telegram and Docupost to Notis once in the portal.
  • 2Create the automation in the portal or ask Notis to create it conversationally.
  • 3Give one plain-language instruction to mail an overdue notice only after you approve it and the recipient, address, sender, and final PDF are confirmed.
  • 4Choose the Telegram new message trigger and a reporting channel.
  • 5Test with one approved notice and confirm the billing address before sending.

Questions about this workflow

Will every overdue invoice mention trigger a letter?

Instruct Notis to require an explicit approval to mail, along with the final notice and verified recipient details.

Can I use this for a postcard reminder?

A postcard can be used if you have approved front and back images and have configured the instruction for that format.
