Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Verify Email
Tool to verify the deliverability of an email address. use when you need to confirm that an email can receive messages before outreach.
Why this helps
Email checks can stall when the person who spots an address also has to remember a separate next step.
- Adds a clear handoff to the existing message.
- Lets a founder batch review and verification signals naturally.
- Keeps routine checks from becoming separate reminders.
Setup
Build it in a few focused steps.
- 1Connect Slack and Findymail to Notis once through the portal.
- 2Create an automation from the portal or ask Notis in plain language.
- 3Tell Notis to verify an address only when the agreed reaction is added to a message that contains the address.
- 4Choose the Slack reaction-added trigger and the channel for run reports.
- 5Test with one real address and the agreed reaction.

Does it contact the address?
