Email Verifier: deliverability, catch-all and risk score

Bulk email verification for list cleaning before a campaign: syntax check, DNS MX lookup, disposable-domain and role-account detection, an optional SMTP RCPT probe with catch-all detection, and a 0-100 deliverability score per address. No third-party validation services in the chain. No email retention: addresses exist only for the duration of the run.

Pricing

You are charged per decisive result, not per address scanned. Unknown and catch-all-uncertain outcomes are free.

This actor runs its own DNS and SMTP logic inside your Apify run. Addresses are not sent to any verification service and are not stored after the run.

What data you get

Field	Description
email	The address checked (lowercased, trimmed)
status	good, risky, bad or unknown
score	0-100 deliverability score
valid	Derived boolean (syntax + MX pass, nothing invalidates)
syntaxValid	Syntax-level result
mxFound	DNS MX record present
disposable	Disposable-domain heuristic hit
roleAccount	Role-account heuristic hit (info@, admin@, ...)
freeProvider	Known consumer mailbox provider
catchAll	True when the domain accepts any mailbox (probe mode)
smtpResult	valid, risky, unknown, invalid or null (probe mode)
technicalReason	SMTP reply code with plain-text DSN meaning
didYouMean	Suggested correction for a likely domain typo
reason	Human-readable summary of the verdict

How to use

1. Add the actor to your Apify account and click Run.
2. Paste addresses into emails. Duplicates are removed automatically and you are charged once per unique address.
3. Optionally enable smtpProbe for mailbox-level checks.
4. Export results as JSON, CSV or Excel.

Input

{
  "emails": ["karl@example.se", "info@example.org"],
  "smtpProbe": false
}

Limitations

These are plain facts about how the checks behave:

• Datacenter IPs receive greylisting; some servers return unknown rather than a verdict. The actor reports unknown and does not charge for it.
• On catch-all (accept-all) domains a 250 reply does not prove the mailbox exists. Such results are marked catchAll=true and reported as risky, and are not charged.
• The disposable-domain list is a static snapshot of the most common disposable providers, not an exhaustive one. disposable=true is reliable; disposable=false does not guarantee a non-disposable domain.
• Some servers block or rate-limit port 25 probes from datacenter ranges. When the probe cannot connect, the actor reports smtpResult=null with a reason and falls back to DNS-layer checks.
• Without the probe, the verdict rests on syntax, MX and heuristics. It does not confirm the mailbox exists.
• did_you_mean suggestions come from a small list of common providers plus domains observed in the run, using a levenshtein distance of 2 or less.
