From paste to age read

How the email age checker works

Three steps, no signup, no card on file. Paste an address, watch the engine weigh domain age against every signal, verdict in two seconds.

001INPUT

Paste the address

Drop any email into the pill — Gmail, Outlook, custom domains, or role aliases like info@ and sales@. Verify one address free right now, or upload a CSV to check a whole list once you sign up.

002ENGINE

Run the 9-check engine

Nine checks fire in parallel: syntax, DNS, and MX records, a live SMTP handshake, catch-all and disposable detection, role and domain-age signals, mailbox state, and email authentication. The full verdict then lands in about two seconds.

003VERIFY

Verdict in 2 seconds

Every address comes back valid, invalid, or risky, with a confidence score, the full per-check breakdown, and a recommended retry policy. Read the result right there on the page, or pull it straight from the API.

Domain age, explained

What email age checkers actually do

Not a notarized birth certificate for a domain. A risk signal, read alongside every other check Verifox already runs.

An email age checker tells you how old, and how established, the domain behind an address is. A newly registered domain is cheap and disposable, exactly why spammers, fraud rings, and throwaway-account farms cycle through them constantly, while a domain that has existed for years represents a real, hard-to-fake investment. Verifox reads that age back to you and folds it into a single verdict alongside whether the domain looks disposable or carries a spammy domain reputation, instead of making you stitch separate lookups together.

See it in action

Everything the checker does, on one screen

From one pasted address to a full CSV, every check runs the same nine-layer engine and hands you a verdict you can send on.

Single check

Verify one email in seconds

Paste an address and the checker runs all nine deliverability layers (syntax to live SMTP) and hands back a verdict, a 0-100 confidence score, and the full check-by-check breakdown. You send to a confirmed inbox, never a hopeful guess.

Bulk & CSV

Verify a whole list at once

Upload a CSV or paste a list, and the checker works the entire batch (the same nine-check engine on every single row), then returns a clean file split into valid, risky, and invalid, ready to export.

/dashboard/lists

API & MCP

Drop it into your stack

One REST call verifies an address and returns the verdict as JSON , with cURL, Node, and Python examples ready to copy. Wiring an AI agent instead? The same verification ships as a native MCP server.

Analytics

Watch your list health over time

Every check you run rolls up into one activity view: volume, valid rate, and risk trends across single checks, bulk jobs, and API calls, so you catch a decaying list before it dents your sender reputation.

What teams are saying

Built for the teams that ship outbound

Growth leads, marketers, and engineers running real campaigns on real lists, with a verified email on every byline.

Thomas George, GTM Lead at Stripe

90% lower bill, 0.4% bounces

We were paying ZeroBounce a four-figure monthly bill and still landing 3% bounces on cold campaigns. Switched the pipeline to Verifox, dropped to 0.4% bounces, and cut the bill by more than 90%.

Common questions

Email age checks, answered

The questions we get from teams that land here to see how old an email's domain is, with the real numbers, real limits, and real opinions behind our verification stack.

Is the email age checker actually free?

Yes. The age read is not a teaser that hides the verdict behind a paywall: you get 4 full checks per day from this page, each one including the domain age estimate, without an account. No card, no signup.

Checking ages across a whole list? Create a free account and you get 1,000 checks on the spot, or 2,500 if your signup email is a work address. Past that, credits are pay-as-you-go and never expire on any paid plan, with volume pricing shown for your region.

How do I check how old an email's domain is?

Paste the email address into the field at the top of this page and run the check. In about two seconds you get the estimated domain age alongside the full per-check breakdown, so you can see at a glance whether the address sits on an established domain or a freshly registered one.

The age read folds into the overall verdict rather than standing alone. A long-lived domain with clean signals returns safe; a domain registered days ago, or one paired with disposable and catch-all patterns, returns risky. If you only need a single address verified at a time, the free email checker runs the very same engine.

Why does the age of an email's domain matter?

Domain age is one of the cleanest legitimacy signals there is. Spammers, fraudsters, and throwaway-account farms churn through newly registered domains by the thousand, because a domain that gets burned this week is cheap to replace next week. A domain that has quietly existed for years, by contrast, represents a real investment somebody is unlikely to torch on abuse.

So the age of an email's domain is a strong proxy for risk. A brand-new domain on a signup form, a sales lead, or a payment is worth a second look, especially when it lines up with other red flags like a disposable domain or a poor domain reputation. Verifox surfaces all of those signals in one verdict.

What does this email age checker actually check?

Nine checks run in parallel every time you check an address, scoring both the domain and the mailbox behind it. Domain age is one of them, read alongside RFC syntax and format validation, domain existence and MX records, a live SMTP handshake with a mailbox-exists ping, disposable-domain and role-address detection, and catch-all detection with AI-confidence scoring.

The verdict folds the domain age estimate together with sender-reputation and blocklist risk so a fresh, throwaway-looking domain reads as risky before it ever reaches your funnel. To screen a domain's reputation specifically, the domain spam checker runs the very same engine.

Can you always tell the exact registration date of a domain?

Not always to the day, and we're honest about that. Plenty of domains hide their WHOIS records behind privacy services or registrar redaction, so a guaranteed creation date isn't available for every domain on earth. That is why Verifox treats domain age as an estimate and a risk signal, not a notarized timestamp.

Where the data is public, we read it directly. Where it is redacted, we lean on corroborating signals (DNS history, certificate history, MX and reputation posture) to place the domain into an age band. Either way the output that matters is the same: established and trustworthy, or new and worth scrutiny.

Does domain age affect email deliverability?

Yes, indirectly but meaningfully. Mailbox providers are wary of mail from domains with no track record, so a brand-new sending domain typically has to be warmed slowly before it earns inbox placement. Send at volume from a cold, freshly registered domain and a large share of that mail quietly routes to spam.

On the receiving side, the age of the domains you mail also matters. Lists padded with throwaway addresses on disposable, days-old domains bounce and generate complaints, which drags down your own sender reputation. Scrub every list with the free email checker first and you keep those risky domains out of your sending stream.

Do you store the emails I run age checks on?

No. The address you paste, the domain we extract from it, and the WHOIS and DNS lookups behind the age estimate are all processed in memory and discarded the moment the verdict returns. No log of what you checked, no record of which domains you were vetting, nothing retained, nothing sold.

We're SOC 2 Type II compliant with the full Trust Center report on request. Read the privacy policy for the byte-by-byte breakdown of what we touch and what we don't.

Can I run an email age check on a list in bulk for free?

Yes. Upload a CSV of addresses and the results come back with a column per check, so every row carries its domain age band alongside the verdict. Sort that column descending and the freshly registered domains, the riskiest rows in any list, float straight to the top. The free signup tier covers 1,000 checks (2,500 with a work email), enough to age-screen most small lists outright.

For larger lists, our paid credit packs are pay-as-you-go and never expire, with pricing localized to your region on the pricing page. CSV upload, API access, and bulk parallel processing are included from the free tier up.

How fast is the API and what's the SLA?

The age lookup adds no latency penalty: it runs in parallel with the other eight checks, so a full verification including the domain age estimate returns in around 380 ms median, sub-50 mswhen the domain's age is already cached. Bulk age screening runs at roughly 10,000 checks per minute on the standard tier.

SLA is 99.9 % uptime on Starter, 99.99 % with an annual Volume contract. Full real-time uptime + incident history at status.verifox.ai. Implementation details in the API docs.

Can I add domain age and risk checks to my own app or AI agent?

Yes. The REST API reference documents the inbound and outbound shapes for every endpoint, so you can drop real-time domain age and risk scoring into signup forms, CRMs, or any tool that speaks REST. HubSpot, Salesforce, Zapier, Klaviyo, Mailchimp, and Brevo all connect out of the box.

Verifox also ships native MCP server support so AI agents (Claude, Cursor, custom LLM apps) can score domain age without glue code. Drop the MCP URL into your agent config and the tools are wired. Credits are pay-as-you-go, never expire, and are refundable for the first 30 days, with full terms in the refund policy.
