Clean an email list before you send. For every address you get one JSON row with a verdict (deliverable, risky, undeliverable or invalid), the reason, the domain's live MX records, and flags for disposable domains, role addresses (info@, support@), free providers and likely typos with a corrected suggestion (someone@gmial.com → someone@gmail.com).
It checks syntax and the domain's DNS mail routing. It does not open SMTP connections to mailboxes (see Limits), so it is fast, deterministic and cheap.
What you get
| Field | Meaning |
|---|---|
verdict | deliverable, risky, undeliverable, invalid or unknown |
reason | domain_not_found, no_mail_server, null_mx, disposable, possible_typo, role_address, invalid_local_part, ... |
valid | Whether the domain can receive mail at all |
mx | Up to 5 MX hosts with priority |
disposable, role, freeProvider, plusTag | Flags |
suggestion | Corrected address when the domain looks mistyped |
Real output
Input: 8 addresses (one duplicate-by-case, one malformed). Real run on Apify:
| verdict | reason | |
|---|---|---|
| support@stripe.com | risky | role_address |
| jane@github.com | deliverable | |
| sam@apify.com | deliverable | |
| test@mailinator.com | risky | disposable |
| someone@gmial.com | risky | possible_typo (suggests someone@gmail.com) |
| nobody@this-domain-does-not-exist-siftwright.com | undeliverable | domain_not_found |
| bad@@x | invalid | invalid_local_part |
7 of the 8 rows were charged (the malformed address was free).
Pricing
Pay per event: $0.80 per 1,000 emails ($0.0008 each) plus Apify's $0.00005 start event.
- Charged once per unique address that gets a definitive verdict.
- Free: invalid syntax, duplicates, and inconclusive DNS lookups (timeouts/SERVFAIL).
- Set a maximum cost per run and the Actor stops exactly at the limit.
How it compares
| This Actor | Typical SMTP-probe verifiers | |
|---|---|---|
| Price per 1,000 | $0.80 | $0.85-$2.50 plus start fees on some |
| Detects disposable / role / typos | Yes | Varies |
| Mailbox-level check | No | Sometimes |
| Failed lookups free | Yes | Varies |
Limits (honest)
- No mailbox-level verification.
deliverablemeans the address is well-formed and its domain publishes mail routing. It cannot confirm that a specific inbox exists; many providers (Gmail, Microsoft 365) block or mask SMTP probes, and outbound port 25 is typically blocked on cloud hosts. - The disposable-domain list is a hand-maintained best-effort list of several hundred well-known services, not an exhaustive database; new throwaway domains appear daily.
- Catch-all domains look
deliverable.
Use it from code
Works with Apify's MCP server, so AI agents can call it as a tool.
FAQ
Why is support@stripe.com "risky"? Role addresses are shared inboxes: valid, but they rarely reach a person and hurt cold-email metrics.
Do you store my list? No. Input and results live in your own Apify run storage.
