Find Slack Users by Email from Telegram Channel Posts
When an email address is mentioned in your Telegram channel, Notis instantly looks up the person's Slack profile and shares their info.
Trigger
New Channel Post
Triggered when a new post is published to a channel where your bot is an administrator.
Action
Lookup users by email
Retrieves the slack user object for an active user by their registered email address; fails with 'users not found' if the email is unregistered or the user is inactive.
Why this helps
You see an email in Telegram but need to manually search Slack to find their profile. Wasting time on manual lookups slows down coordination.
- Instant user lookups without switching apps
- Find profiles by email mention in Telegram
- Faster team coordination and context
- Reduces manual Slack searching
Setup
Build it in a few focused steps.
- 1Connect Telegram and Slack to Notis.
- 2Create an automation with trigger 'New Channel Post' in your Telegram channel.
- 3Write the prompt: 'If an email address is mentioned, look up that user in Slack and reply with their profile info'.
- 4Test by posting an email address in Telegram and verifying the Slack user info is returned.
