Email Validator — Email Address Check

Check the validity of email addresses: format, syntax, MX record, disposable domains, role accounts. Single or bulk validation up to 50 addresses at once. Typo detection.

TL;DR

How to check the validity of an email address?

Email Validator checks 6 items for each address: 1) Format (regex check for @ and valid characters), 2) Syntax (local part length, number of dots), 3) Domain (TLD validity, structure), 4) MX record (does an email server exist for that domain — real DNS query), 5) Disposable detector (tempmail, mailinator, 10minutemail), 6) Role account (info@, admin@, support@ — not personal). Plus typo suggestion (gmial.com → gmail.com). Risk and deliverability score for each address.

  • 6 checks — format, syntax, domain, MX, disposable, role
  • Real DNS MX query — verifies if email can arrive
  • Bulk validation up to 50 addresses at once (CSV-friendly)
  • Typo detection — gmial.com → gmail.com

Email Validator

Single mode za jednu adresu sa detaljnim 6-step izveštajem, ili Bulk mode (do 50 adresa).

Guide

6 levels of email address verification

Each address is checked at 6 different levels before getting a „Valid“ status.

Format & syntax

RFC 5322 regex + length of local part (max 64) and domain part.

Domain & TLD

Checking the structure of the domain and a valid TLD (min 2 characters).

MX record

Real DNS query for MX — does the domain have an email server?

Disposable detection

List of 12+ disposable providers: tempmail, mailinator, yopmail, 10minutemail.

Role accounts

info@, admin@, support@, webmaster@ — not personal, signal for marketing campaigns.

Typo detection

gmial.com → gmail.com, yahooo.com → yahoo.com — automatic correction suggestion.

Why is email address validation important?

Email marketing campaigns with a high bounce rate (>5%) damage the domain's reputation. Gmail, Outlook and Yahoo penalize senders with many bounces — your future emails may start going to spam.

Validation before sending a campaign reduces bounce rate from a typical 3-5% to <1%. This saves money (mailing services charge per valid address), improves domain reputation and increases open rates.

Format vs deliverability

Valid format is NOT the same as a deliverable email. Format check only verifies the regex structure (john@beohosting.com is a valid format). But whether john@beohosting.com actually receives email — that is shown by MX check + domain reputation. Our tool does both.

Bulk vs single mode

Single mode is ideal for individual checks (lead form submit, contact form). Bulk mode (up to 50 addresses) is for marketing lists before a campaign. For enterprise (1000+ addresses) we recommend dedicated services like ZeroBounce or NeverBounce.

Frequently asked questions - Email Validator

Odgovori na najčešća pitanja o našim uslugama.

An MX (Mail Exchange) record is a DNS record that defines an email server for a domain. If a domain has no MX record, emails sent to that domain cannot be delivered. Our tool performs a real DNS MX query for each address — if the MX record does not exist or is invalid, deliverability is low.

Disposable emails (tempmail, mailinator, 10minutemail) are temporary email services that are activated for 10 minutes - 1 hour. Users use them to bypass registration without real emails. Leads with a disposable email have value close to zero — they cannot be contacted again after expiry.

Role accounts are email addresses that represent a function in a company, not a person. Typical examples: info@, admin@, support@, sales@, contact@, webmaster@, abuse@. For B2B marketing they are not bad, but for personal direct mail (cold outreach) a real personal email is needed to have a chance of a reply.

Our bulk mode supports up to 50 addresses per query (due to the rate limit on the MX query API). For 10,000+ addresses we recommend dedicated email validation services like ZeroBounce, NeverBounce or Kickbox. Our tool is ideal for small marketing campaigns, lead form checks and internal list cleanup.

No. The MX query goes directly via our API to the DNS resolver (Google Public DNS 8.8.8.8). The email addresses you check are not stored in our database, not logged, and not used for any other purpose. 100% private.
