Check introduction emails from Slack DMs
Keep a useful introduction moving by checking the address before it becomes another item to revisit.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
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
An introduction arrives privately, and its email address gets copied into notes without a deliverability check.
- Check an address at the moment an introduction arrives.
- Avoid carrying a questionable email into follow-up notes.
- Get a concise result in your selected run-report channel.
Setup
Build it in a few focused steps.
- 1Connect Slack and Abstract to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis in plain language to validate email addresses in Slack introductions.
- 3Use one instruction: when a DM includes an introduced person's email, validate it with Abstract and report the result without contacting them.
- 4Choose the Slack direct message trigger and a channel for run reports.
- 5Test with one real introduction email.
Questions about this workflow
Will Notis reply to the person who sent the DM?
The instruction asks Notis to report the validation result in your selected channel; it does not ask it to reply to the DM.
Can it check an address without an introduction context?
You can adjust the plain-language instruction to cover any email shared in DMs.
