Email Verifier APIAutomate email verification with our powerful API. Seamlessly integrate real-time email checks into your platform to collect only valid and active addresses.Expore our API3 Types of Verification Results
and How to Use Them
ValidSafe to Send97%+ delivery rate guaranteed
A "valid" result means the receiving server has confirmed the email exists and is accepting messages. These addresses have passed SMTP checks and, if needed, additional verification techniques. You can confidently send to these contacts knowing they are real, active inboxes. Valid results help maintain your sender reputation and maximize your cold outreach performance.RiskyUse With Caution~65% delivery rate probability
A "risky" result means we couldn't confirm whether the email is valid or invalid. This usually happens with catch-all domains where even advanced techniques can't break through, or with email servers that are greylisted or respond too slowly. You can still choose to send to these addresses, but we recommend doing so from a secondary sending domain where reputation risks are minimized.InvalidDo Not Send
An "invalid" result means the email address is not usable. The server has confirmed it doesn't exist, the mailbox is full or inactive, or the domain is not set up to receive mail. Sending to these addresses will increase your bounce rate and harm your sender reputation. These contacts should be removed from your list immediately.Who Is Our Email Verifier Designed For?

Frequently Asked Questions
How does email verification work?
Email verification confirms whether an email address exists, is active, and can safely receive messages - without sending an actual email. This process prevents bounces, protects your sender reputation, and improves overall deliverability. We use real-time techniques like SMTP pinging, domain validation, and advanced fallback methods to verify even difficult addresses like catch-alls.
What does your email verifier check for?
Anymail Finder performs a comprehensive verification process to ensure only the most accurate results are delivered. Those includes:
- Syntax validation
- Gibberish detection
- Domain existence
- DNS and MX record validation
- Catch-all domain detection
- SMTP authentication (email address ping)
- Advanced techniques for hard-to-verify or protected addresses (e.g. behind Proofpoint or Mimecast)
How accurate is the Anymail Finder Email Verifier?
We guarantee over 97% delivery accuracy for all emails marked as "valid". Thanks to our advanced multi-layered verification system, you'll get results that outperform most tools - especially on catch-all domains and those protected by Secure Email Gateways (SEGs).
Does Anymail Finder send test emails to check validity?
No, we only use non-intrusive methods, such as SMTP checks, domain and MX record validation, and advanced catch-all detection to determine whether an email is valid.
How does email verification help with deliverability?
Verifying your email list helps you avoid invalid or risky addresses that could bounce or trigger spam filters. This protects your sender reputation, reduces bounce rates, and increases the chance your emails land in the primary inbox - not the spam or promotions tab.
Can an email marked "valid" still bounce?
While rare, it's possible. There are two main reasons:
- Hard bounce: The mailbox has become invalid since verification.
- Soft bounce: Your domain or IP may be flagged by the recipient's server.
How often should I clean my email list?
We recommend verifying your list every 2 to 4 months, or before major campaigns.
Clean more often if:
Clean more often if:
- You run cold outreach regularly
- You've purchased or scraped email lists
- You notice a drop in open rates or a rise in bounces
Can I verify email addresses in bulk?
Yes. You can upload a CSV or Excel file with up to 100,000 rows and verify all emails in seconds. Results are instantly sorted into valid, risky, or invalid so you can take action immediately.
Can I integrate the verifier into my CRM or tools?
Yes. Our Email Verifier API and integrations with Zapier, Make.com, and other platforms let you verify emails in real-time directly inside your CRM, signup flow, or outbound email system - no manual steps needed.
What happens if I verify the same email more than once?
You'll only be charged once per email within a 30-day window. If you verify the same address multiple times during that period, you won't be charged again.
Is the email verifier free to use?
Yes. We offer a 3-day free trial so you can test our email verifier with no commitment. Learn more on our pricing page.
How much does one email verification cost?
Each email verification costs 0.2 credits, so with 1 credit, you can verify 5 emails.
Examples:
Check our pricing page to see how much credits cost.
