Type an email to begin basic validation.
What does an Email Validator do?
An Email Validator is a diagnostic tool used by developers and marketers to determine if an email address is capable of receiving messages. It operates in stages: first verifying the mathematical formatting (Syntax Check), identifying known high-risk providers (Disposable Check), and finally, querying the global internet registry to ensure mail servers actually exist for that domain (MX Check).
How we validate
- • RFC-5322 Syntax: Ensures the structure is mathematically perfect.
- • Typo Detection: Catches common mistakes like "gamil.com".
- • Disposable Check: Flags known temporary email providers.
- • DNS Verification: Securely queries domain MX records.
Why you need it
- • Protect Reputation: Prevent hard bounces that ruin deliverability.
- • Clean Data: Keep CRMs free of fake users.
- • Save Money: Don't pay your ESP to send emails to dead inboxes.
- • Increase ROI: Higher deliverability means higher conversion rates.
How to Use the Email Validator
How it Works
- 1
Enter the Email Address
Type or paste the email address into the input field. As you type, the tool will instantly run a robust syntax check to ensure it follows standard formatting rules. - 2
Review Basic Heuristics
The status card will immediately inform you if the syntax is valid, if there's a common typo (like 'gamil.com'), or if it belongs to a known temporary/disposable email provider. - 3
Deep Check the Domain
Click 'Deep Check Domain' to securely query the global DNS network. This will verify if the domain has active MX (Mail Exchanger) records configured to actually receive emails.
Frequently Asked Questions
Frequently Asked Questions
Sending emails to addresses that do not exist causes "hard bounces". Email providers (like Gmail and Outlook) track your bounce rate. If it gets too high, they assume you are a spammer and will route all your future emails directly to the junk folder. Validation protects your sender reputation.
Absolutely not. We use a passive validation method. First, we check the syntax mathematically. Then, if requested, we query the public DNS system to ask, "Does this domain have servers capable of receiving mail?" No messages are sent to the user.
An MX record is a rule in the Domain Name System (DNS) that specifies which mail server is responsible for accepting email messages on behalf of a domain name. If a domain lacks an MX record, it physically cannot receive emails.
Disposable emails (often called 10-minute emails) are used by people who want to download a freebie or bypass a registration gate without giving you their real contact info. Marketing to these emails is useless and hurts your engagement metrics.
