Screen Canvas submission emails for disposable domains
Spot disposable email domains in new assignment submissions without pausing to check them by hand.
Trigger
New Canvas Assignment Submission
Fires when a new submission is made for an assignment.
Action
Check Disposable Domain
Checks whether an email domain is disposable, including its DNS records.
Why this helps
Reviewing submission details one at a time makes it easy to miss disposable addresses and adds another task to a busy course workflow.
- Automatically checks the submitted email domain when a new submission arrives.
- Gives you a quick signal to review before relying on the address for follow-up.
- Reduces manual context switching between Canvas and email validation.
Setup
Build it in a few focused steps.
- 1Connect Canvas and Emaillistverify once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to check the submitted email domain for disposable-domain signals and summarize the result for review.
- 4Pick New Canvas Assignment Submission as the trigger and choose where run reports go.
- 5Test with one real submission and confirm the result is useful.
Questions about this workflow
Does this workflow reject the submission?
No. The check provides a disposable-domain signal for review. It does not reject or change a Canvas submission.
What does the trigger monitor?
It polls Canvas for new submissions to a specific assignment. Choose the assignment when selecting the available trigger.
Does the check confirm that the full email address can receive mail?
No. This action checks whether the email domain is associated with temporary or disposable addresses. It is not a full deliverability check.
