Use a Reaction to Request a Permitted Email Review
A visible review signal can reduce follow-up while the consent record stays in the original Slack message.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Query gender by email address
Tool to determine gender from an email address. Use when you need to infer gender for personalization after obtaining proper consent.
Why this helps
A requested check can slip through when it is only mentioned in a busy thread.
- Makes a requested review easier to notice.
- Requires consent to be recorded in the message first.
- Returns the inference for a human to assess.
Setup
Build it in a few focused steps.
- 1Connect Slack and GenderAPI.io to Notis once through the portal.
- 2Ask Notis to query the email when the designated reaction is added to a Slack message documenting consent for that purpose.
- 3Pick the Slack reaction added trigger and choose a channel for run reports.
- 4Test with a real permitted message and review the returned inference.
Questions about this workflow
Does adding the reaction authorize the lookup?
No. The message itself must document explicit permission; the reaction only requests the review.
Should the result automatically change how a contact is treated?
No. It is an uncertain inference for human review, not verified identity information.
