Trigger
Subscribe Trigger
Triggered when a subscriber subscribes to Mailchimp
Action
Get Gas Price Distribution
Tool to retrieve the current mempool gas price distribution breakdown. use when analyzing gas price trends or preparing fee strategies.
Why this helps
A generic gas number can miss whether the mempool is crowded, making onboarding estimates harder to trust.
- See fee market shape at onboarding time
- Spot congestion before a fee-sensitive step
- Keep the report tied to a real subscriber event
Setup
Build it in a few focused steps.
- 1Connect Mailchimp and Blocknative once in Notis.
- 2Create an automation for subscriber mempool snapshots.
- 3Tell Notis to retrieve the current mempool gas price distribution after each subscription and explain how it affects the onboarding operation you name.
- 4Pick the Subscribe Trigger, select a report channel, and test with one real subscription.
