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.
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 for one address with detailed 6-step report, or Bulk mode (up to 50 addresses).
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.
