Email Verifier, Finder & Deliverability Checker

Verify known emails, find publicly listed business contact emails, and audit domain email authentication in one batch. The Actor exports transparent MX, SPF, DMARC, DKIM, provider, disposable, role-account, and confidence signals without treating MX records as proof that a mailbox exists.

Who is it for?

Sales operations teams, lead-generation agencies, recruiters, founders, and developers can use this Actor to qualify public business-contact data and diagnose domain email setup before outreach.

What you can do

• Clean CRM and lead-list emails before outreach.
• Find a named person's email when it is publicly listed on the supplied company website.
• Audit company domains for mail routing and authentication gaps.
• Separate invalid, risky, ready, not-found, and domain-only results.
• Process up to 10,000 deduplicated targets with bounded concurrency and resumable cutoff evidence.

Input settings

Key	Type	Description
emails	string[]	Known email addresses to check.
contacts	object[]	Objects with firstName, lastName, and domain; only publicly evidenced matches are returned.
domains	string[]	Domains to audit without inventing an email address.
csvText	string	Comma, whitespace, or newline-separated email addresses.
maxConcurrency	integer	Concurrent independent targets, from 1 to 25.
maxRuntimeSecs	integer	Runtime budget from 60 to 270 seconds.

At least one target is required. Inputs are deduplicated before network work.

Output fields

Field	Description
email	Submitted or publicly evidenced email; null for domain-only/not-found rows.
firstName, lastName	Submitted contact identity when using finder mode.
domain	Normalized ASCII mail/company domain.
isValidFormat, syntaxErrors	Local syntax result and explicit issue codes.
hasMxRecords, mxHost	Public mail-routing result and preferred host.
isVerified	Conclusive mailbox result; null when no authorized mailbox probe was performed.
isCatchAll	Conclusive catch-all result; null when not tested.
isDisposable, isFreeProvider, isRoleAccount	Address risk classifications.
confidenceScore	Deterministic 0–100 confidence for the supplied/evidenced address.
verificationMethod	Deepest supported check: domain, format, or mx.
provider	Provider inferred from the preferred MX hostname.
patternsTried, sources	Finder work count and public evidence routes.
verificationTimeMs	Processing time for the row.
deliverabilityGrade, deliverabilityScore	Domain authentication grade and 0–100 score.
spfExists, spfValid	SPF publication and basic version validity.
dmarcExists, dmarcPolicy	DMARC publication and policy.
dkimFound	Whether one of several common public selector records was found.
deliverabilityIssues	Explicit mail/authentication issue codes.
status	READY, RISKY, INVALID, NOT_FOUND, DOMAIN_ONLY, or FAILED.
checkedAt	ISO timestamp for freshness.

Input recipes

Verify a pasted list

{ "csvText": "hello@example.com\nsales@example.org" }

Find a public contact email

{ "contacts": [{ "firstName": "Jane", "lastName": "Smith", "domain": "example.com" }] }

Pricing

The Actor uses pay-per-event pricing: one small start charge per run and one result charge after each dataset row is saved. See the live Actor Pricing tab for current account-tier rates. Failed targets that produce no row are not charged as results.

Limits and data availability

• The maximum batch size is 10,000 unique targets; finder mode checks a bounded set of public company pages.
• Results depend on public DNS and website availability. Missing public evidence produces NOT_FOUND rather than a guessed address.
• A valid format and MX record do not prove that a specific mailbox exists.
• isVerified: null and isCatchAll: null mean the claim was not conclusively tested, not false.
• DKIM selectors are chosen by each sender; common-selector discovery is useful but not exhaustive.
• Public contact discovery returns only an address found on the supplied company's public pages and textually matching a conventional person pattern.
• DNS changes can take time to propagate; use checkedAt when comparing runs.
• Large workloads may stop before the platform cutoff and preserve pending targets in the run key-value store.

API usage

FAQ

Does this send email?

No. It analyzes supplied/public addresses and domain mail configuration.

Does an MX result prove the mailbox exists?

No. The Actor reports mailbox-only claims as null unless conclusively supported.

Why is DKIM false when a domain sends signed mail?

The domain may use a custom selector not included in the bounded common-selector check.

Can I combine all modes?

Yes. emails, contacts, domains, and csvText can be submitted together.
