Check investor email addresses before outreach
Catch invalid or disposable addresses before they create extra follow-up work.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Email Address Verification API
Checks an email address’s format, domain, and disposability.
Why this helps
An incorrect address can waste a carefully prepared introduction and leave a founder unsure whether outreach ever reached its destination.
- Check supplied addresses before an outreach task proceeds.
- Surface syntax, domain validity, and disposability signals.
- Keep the verification request tied to the deal outreach context.
Setup
Build it in a few focused steps.
- 1Connect Affinity and Big data cloud once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3Tell Notis to verify the email address included in an investor outreach request and summarize the result.
- 4Choose the webhook trigger and select where run reports should go.
- 5Test with one real example containing an email address.
Questions about this workflow
Does the verification send an email?
No. The listed action verifies an address; it does not send outreach.
Can it verify an address if none is supplied?
No. Include the email address in the webhook request for Notis to run the check.
