What is an email validator?

An email validator (also called email verifier or email checker) is a tool that checks if an email address is valid, properly formatted, and likely to receive emails. It helps reduce bounce rates and improve email deliverability.

Is this email verifier free?

Yes, our email verification tool is completely free with no limits. Validate as many emails as you need - no registration or payment required.

Do you store or send the emails I validate?

No. All validation happens locally in your browser using JavaScript. No email addresses are sent to our servers or stored anywhere. Your data remains 100% private.

What does the validator check?

Our email checker validates: email syntax/format, domain existence, disposable email detection, common typos, role-based emails (info@, support@), and free email provider detection.

Can I validate emails in bulk?

Yes! Paste multiple email addresses (one per line or comma-separated) and click "Validate All Emails" to check them all at once. Export valid or invalid results separately.

What are disposable emails?

Disposable emails are temporary email addresses from services like Mailinator, Guerrilla Mail, or 10MinuteMail. They are often used to avoid spam but expire quickly, making them unreliable for marketing.

Why are role-based emails flagged?

Role-based emails (info@, support@, sales@) are often managed by multiple people or automated systems. They have higher bounce and complaint rates, so many marketers prefer to avoid them.

How accurate is email validation?

Our syntax, format, and disposable detection is highly accurate. However, client-side validation cannot verify if a specific mailbox exists - that requires server-side SMTP verification.

Can I export the validation results?

Yes. After validation, use "Export Valid" to download only valid emails, or "Export Invalid" to get the list of problematic addresses for review.

Does this work with any email provider?

Yes, the email validator works with all email providers including Gmail, Yahoo, Outlook, corporate emails, and custom domains.

Spam Word Checker FAQ

What is a spam word checker?

A spam word checker analyzes your email content for words and phrases that commonly trigger spam filters. It helps you identify problematic content before sending so your emails reach the inbox instead of the spam folder.

Is this spam checker free?

Yes, completely free with no limits. Check as many emails as you want without registration or payment.

What are spam trigger words?

Spam trigger words are words and phrases that email spam filters look for. They fall into categories like urgency ("act now"), money ("free", "discount"), promises ("guarantee"), and pressure tactics ("limited time"). Using too many can cause your email to be flagged as spam.

How does the spam score work?

The spam score (0-100) indicates how likely your email is to trigger spam filters. 0-30 is good (low risk), 31-60 is moderate (some risk), and 61-100 is high risk. The score considers the number of spam words, their severity, and frequency.

Will removing spam words guarantee delivery?

Removing spam words significantly helps, but email delivery depends on multiple factors including sender reputation, email authentication (SPF/DKIM/DMARC), recipient engagement history, and sending patterns. This tool addresses the content aspect.

Do you store my email content?

No. All analysis happens locally in your browser using JavaScript. Your email content is never sent to our servers or stored anywhere.
