Validate email contacts from new Telegram group members
Make the first welcome follow-up easier to deliver.
Trigger

Triggered when a new member joins a group or supergroup the bot belongs to, including when the bot itself is added.
Action
Email Validation
Tool to validate whether an email address is real and deliverable. use after collecting an email address to confirm deliverability.
Why this helps
A new member's contact detail can get lost in introductions, and a typo can make the welcome message bounce.
- Check a shared address while the introduction is recent.
- Reduce missed welcome or onboarding messages.
- Give the community manager one less manual check to remember.
Setup
Build it in a few focused steps.
- 1Connect Telegram and Abstract to Notis once in the portal.
- 2Create an automation for new member contact checks.
- 3Write one plain-language prompt asking Notis to validate an email when a newly joined member shares it as their contact address.
- 4Choose Telegram New Chat Member as the trigger and select where run reports should go.
- 5Test with a real group join followed by a member sharing a contact email.
Questions about this workflow
Will joining alone start an email check?
No email can be checked unless an address is available in the trigger context or subsequent message. The prompt should act only when a shared contact email is present.
Does this send a welcome message?
No. It validates the address and reports the result.
