Question 1

How accurate is the email checker?

Accepted Answer

Our email checker has over 95% accuracy. It performs multiple validation checks including syntax, DNS, MX records, and optional SMTP verification. For maximum accuracy, enable Deep Check which directly verifies with the mail server.

Question 2

Is the email checker really free?

Accepted Answer

Yes! MailYogi's email checker is completely free with unlimited checks on our website. No signup, no credit card, no hidden fees. We also offer API access for developers with both free and paid tiers.

Question 3

Do you store the email addresses I check?

Accepted Answer

No. We respect your privacy. Email addresses entered are validated in real-time and never stored in our database. All checks are ephemeral - once you leave the page, the data is gone.

Question 4

What's the difference between syntax and SMTP verification?

Accepted Answer

Syntax validation checks if the email format is correct (like having an @ sign). SMTP verification goes further by connecting to the actual mail server to confirm the mailbox exists and can receive emails. SMTP is more accurate but takes longer.

Question 5

Can I check multiple emails at once?

Accepted Answer

The homepage checker validates one email at a time for instant results. For bulk email verification, we offer a separate bulk checker tool that can process CSV files with thousands of emails.

Question 6

Why does SMTP check sometimes fail?

Accepted Answer

SMTP verification requires connecting to the recipient's mail server on port 25, 587, or 465. Some cloud hosting providers block these ports for security. If SMTP fails, we still provide accurate results using DNS and MX validation.

Question 7

What are disposable email addresses?

Accepted Answer

Disposable emails are temporary addresses from services like 10minutemail, TempMail, or Guerrilla Mail. They're often used for spam or fake signups. Our checker identifies these to help you maintain a quality email list.

Question 8

Does email checking work for international domains?

Accepted Answer

Yes! Our checker supports international domains and email addresses with unicode characters (IDN domains). We validate emails across all TLDs including country-specific extensions like .uk, .de, .jp, and more.

Question 9

Can I integrate email checking into my website?

Accepted Answer

Absolutely! We offer a developer-friendly API for integrating email validation into your applications. Contact us for API access and documentation to embed real-time email checking in your signup forms or applications.

Question 10

How does your checker handle typo suggestions?

Accepted Answer

Our checker automatically detects common typos in popular domains (like @gmai.com instead of @gmail.com) and can suggest corrections. This helps users fix mistakes before submitting forms.
