Check signup emails for disposable domains
Add a disposable-domain signal to the moment someone submits an email address.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Check Disposable Domain
Checks whether an email domain is disposable, including its DNS records.
Why this helps
Temporary addresses can add noise to a signup list, and checking them manually interrupts the flow.
- Check the submitted email domain as part of a webhook-started workflow.
- Use the result to inform a signup review or next step.
- Reduce manual checking of temporary email domains.
Setup
Build it in a few focused steps.
- 1Connect Emaillistverify in the Notis portal and connect the system that will send the webhook request.
- 2Create an automation in Automations, New Automation, and give it a clear name.
- 3Tell Notis to check the submitted email for a disposable domain and summarize the result for your signup review.
- 4Choose the webhook trigger and a report channel, then test with one real example request containing an email address.
