- Know whether an address appears deliverable before drafting outreach.
- Reduce the chance of a follow-up going to a bad address.
Setup
Build it in a few focused steps.
- 1Connect Slack and Emailable to Notis once in the portal.
- 2Create an automation and name it for introduction checks.
- 3Tell Notis in one plain-language prompt to verify addresses in Slack messages that introduce a person and report the result.
- 4Choose Channel Message Received, select a run-report channel, and test on one real introduction message.
Questions about this workflow
Can Notis decide whether a message is an introduction?
Describe the introduction context in the prompt, such as a message that names a new contact and includes their email address.
Does verification guarantee a person will reply?
No. It reports email verification details, not whether someone will respond.
