Disposable Email Checker

Detect disposable, temporary and throwaway email addresses with single or bulk email checks. IronDome covers more than 1 million disposable email addresses across Gmail, Outlook, Hotmail, Yahoo, education and private domains. Detection data updates every hour.

The global edge API achieved warm p95 latency below 20 ms in all four tested regions in the published benchmarks, using reused connections. These are API measurements; total Actor runtime also includes Apify startup, storage and billing.

The Actor returns a disposable-email flag, provider, syntax validity, and reason. It does not verify that a mailbox exists or that a message will be delivered.

Pricing and limits

• $0.001 per successful email check ($1 per 1,000), including Apify platform usage. Disposable addresses and duplicates count as successful checks. Invalid-email results are not charged.
• Free Apify plans: up to 10 attempted addresses per run. Paid plans support up to 10,000 addresses per run, subject to your run budget.
• Choose a maximum run charge before starting. The Actor stops at the budget or plan limit and may return partial results.

No IronDome API key is required.

Input

Provide exactly one of email or emails.

One address:

{"email":"person@example.com"}

A list:

{"emails":["person@example.com","another@gmail.com","not-an-email"]}

Lists support up to 10,000 addresses, processed through IronDome's bulk endpoint in batches of up to 100. Order and duplicates are preserved. Each address must contain 1-254 UTF-8 bytes, with no control characters. The total input limit is 3 MB. Other invalid syntax is reported as an invalid-email result.

Results

Results appear in the run's default dataset. A completed check looks like this:

{"index":0,"email":"person@example.com","provider":"custom","valid":true,"disposable":false,"reason":"not_listed"}

An invalid address produces an uncharged row:

{"index":2,"email":"not-an-email","error":{"code":"invalid_email","message":"Provide a syntactically valid email address."}}

index is the zero-based input position. valid describes syntax, not mailbox existence or deliverability.

Budgets and partial results

The Actor stops at the run budget or the 10-address per-run free-plan allowance. It can finish successfully with partial results. The budget bounds attempted addresses: USD 0.01 allows at most ten attempts. Invalid results are not charged, but do not free up additional attempt slots.

For runs that process input, open IRONDOME-STATE in the default key-value store (or the run's state output link). Check processed, completed, invalid, and stoppedAtLimit before assuming the whole list was checked. A free-plan rejection produces no dataset rows or state record; use its run status message instead.

If a service or storage failure interrupts a run, earlier results and charges can remain. Inspect the state and charge ledger before starting another run. Do not resurrect a failed run: automatic resume is not supported. If a charge succeeded but dataset delivery failed, saved batch results can be recovered from the default key-value store using the state's batchKey.

Email addresses are sent to IronDome for classification and stored in the run's input and results. Use appropriate Apify access and retention settings.
