Notis

Check gas conditions when a subscriber unsubscribes

An unsubscribe can start cleanup, revocation, or settlement work. Notis gives that handoff current gas context before anyone acts.

Trigger

Unsubscribe Trigger

Triggered when a subscriber unsubscribes from Mailchimp

Action

Get Gas Prices

Tool to fetch gas price estimates for specific inclusion probabilities. use when you need gas price ranges for the next block or next ~10 seconds.

Why this helps

Exit workflows often run on autopilot, even when network costs make a cleanup step unusually expensive.

  • Add fee context to offboarding
  • Catch costly cleanup windows
  • Keep exit operations visible

Setup

Build it in a few focused steps.

  • 1Connect Mailchimp and Blocknative once in Notis.
  • 2Create an automation for unsubscribe gas impact checks.
  • 3Tell Notis to fetch current Blocknative gas prices after an unsubscribe and summarize the fee implications for the cleanup or settlement operation you provide.
  • 4Select the Unsubscribe Trigger, choose a report channel, and test with one real unsubscribe.

Questions about this workflow

Does unsubscribing itself create a blockchain action?

No. The workflow only checks gas prices for any related operation you describe.

Can it alert me only when costs are high?

Ask Notis to flag high costs using a threshold you provide.
