Question 1

How does email verification work?

Accepted Answer

Email verification checks syntactic format, domain existence, MX records, and sometimes performs SMTP verification. It helps identify typos, fake emails, and delivery issues before sending messages.

Question 2

What is the difference between syntax verification and deliverability verification?

Accepted Answer

Syntax verification checks that the email format is correct. Deliverability verification goes further, checking if the domain exists, if it has mail servers, and if it can potentially receive emails.

Question 3

Can email verification be 100% accurate?

Accepted Answer

No verification is 100% accurate. Some valid emails may be marked as invalid due to server configuration, and some invalid emails may pass basic checks. Use verification as a filter, not as an absolute truth.

Question 4

What are disposable email addresses?

Accepted Answer

Disposable emails are temporary addresses that expire after a short time. They are often used to avoid spam but can indicate low-quality registrations. Our tool identifies many common disposable email providers.

Question 5

Is it legal to verify email addresses?

Accepted Answer

Yes, verifying the email addresses you have collected is legal and good practice. However, ensure you comply with privacy laws (GDPR, CCPA) and only verify emails you are authorized to process.

Question 6

How does email verification improve deliverability?

Accepted Answer

By removing invalid email addresses, email verification reduces bounce rates, which improves sender reputation and, consequently, the deliverability of your email campaigns.

Question 7

Can email verification prevent phishing attacks?

Accepted Answer

Email verification does not directly prevent phishing attacks. However, it can help identify fake or malicious emails that use spoofed or non-existent domains, adding an extra layer of security.

Question 8

What is the impact of invalid emails on my contact list?

Accepted Answer

Having a large number of invalid emails in your list can lead to high bounce rates, which damages your sender reputation, causing your emails to be flagged as spam or blocked by email providers.
