Is that email address real?
Syntax, live mail-server lookup, disposable-domain and role-account detection — in about a second.
Under the hood
Four checks, one verdict.
Syntax
The address is parsed against the actual email format rules — not just "does it contain an @". Typos like double dots, illegal characters, and malformed domains all surface here.
MX records
A live DNS query asks the domain: which servers receive your mail? No MX records means no mailbox anywhere — every message will bounce, and bounces damage your sender reputation.
Disposable domains
Temp-mail services hand out addresses that die within minutes. They pass syntax and MX checks, then never open a single email — this check catches them by domain.
Role accounts
info@, support@, billing@ — shared inboxes read by nobody in particular. Fine for invoices; a wasted send (and a spam-complaint risk) for marketing.
Why verify at all
Bounces are expensive.
Every bounced email is a mark against your sending domain. Mailbox providers watch bounce rates closely — cross a few percent and even your legitimate mail starts landing in spam. Verifying addresses before they enter your list is the cheapest deliverability insurance there is: it filters the typos at signup, the throwaway addresses from giveaways, and the long-dead mailboxes in imported lists before any of them can hurt you.
Questions
Fair questions, straight answers.
How does the email verifier work?
Four checks run in about a second: the address is parsed against the email syntax rules, the domain's DNS is queried live for MX records (the servers that would actually receive the mail), the domain is matched against a continuously updated list of disposable/temp-mail providers, and the mailbox name is checked against known role accounts like info@ or support@.
Is it really free? What's the limit?
Yes — no signup, no email gate. It's rate-limited to 10 checks a minute per visitor to keep it fast for everyone. If you need to verify hundreds or thousands of addresses, the Volanea API's /v1/verify endpoint does the same checks in bulk, and the free tier needs no card.
Can any tool guarantee an address is deliverable?
No — and be suspicious of tools that claim otherwise. The only way to know for certain is to send a real message. What verification can do is catch the addresses that will definitely fail (bad syntax, no mail server) or hurt engagement (disposable domains), which is most of the value at a fraction of the risk.
Do you store the addresses I check?
Checks are processed in memory and not saved to any list. The address you type is used for the lookup and returned to you — that's the whole lifecycle.
Need to verify a whole list?
The same checks run in bulk through the Volanea API — plus sending, campaigns, and automation on 1,000 free credits a month.
