Short answer

How can I stop disposable emails from entering my workflow?

Your AI uses the check_disposable tool to inspect email addresses from new form submissions. It flags addresses from temporary providers so you only work with real users. You'll see how the filtering logic works below.

Where your data lands.

Clean data outcomes.

The AI sorts every submission based on the email provider's legitimacy.

CLEAN

Valid leads stay

The AI confirms the email is from a legitimate provider. These entries move straight into your main workflow or CRM.

FLAGGED

Disposable emails caught

The AI identifies temporary or burner addresses. These are marked for review or discarded to prevent junk data.

REJECTED

Automated blocking

The AI identifies high-risk entries. You can set your agent to ignore these entirely so they never reach your eyes.

REVIEW

Human check needed

If the AI finds a suspicious but non-obvious provider, it flags the entry for you to inspect manually.

FAQ

How this task behaves.

  • 01

    Can the AI delete the form entry automatically?

    No. The AI can flag or route the data, but it does not have permission to delete records from your external apps.

  • 02

    Does it work with any email provider?

    It works with any email address, but it specifically identifies those coming from known disposable or temporary providers.

  • 03

    Will it block my own business email?

    No. The tool only flags addresses from providers known for temporary, short-lived accounts.

  • 04

    Can the AI change the email address to a real one?

    No. The AI can only identify if an address is disposable; it cannot verify the identity of the person behind it.

  • 05

    How does it know which emails are disposable?

    It uses the check_disposable tool to cross-reference the domain against a database of temporary email services.
