Engineered for Accuracy

The checks we run on every address you send us.

Disposable Detection

Instantly identify temporary burner emails to prevent fake signups and keep your database clean.

Deep MTA Validation

We perform a full SMTP handshake to verify the mailbox exists without actually sending an email.

Spam Trap Removal

Advanced detection of spam traps and honeypots that can ruin your domain reputation.

High Speed Processing

Verify thousands of emails per minute using our high-concurrency cloud infrastructure.

Soft Bounce Check

Detect statuses like Mailbox Full or Disabled to save valuable leads.

Domain Analysis

Checks MX records and domain health without sending actual emails.

Why a Clean List Matters

Clean data costs less to send and lands where it should.

Better Deliverability and Open Rates

Fewer bounces mean a stronger sender reputation, so your emails land in the inbox instead of the spam folder.

Stop Paying for Dead Addresses

Your email service provider charges per subscriber. Removing invalid addresses cuts that bill immediately.

Know Exactly What to Send

Every address comes back with a clear status and a score, so you keep the safe ones and decide about the rest.

Protect Your Domain Reputation

A bounce rate above 2% can get a domain blacklisted. A verified list keeps you well below it.

Real Users, Not Fake Sign-ups

Block disposable and fake emails at registration and build a list of people you can actually reach.

Your Data Stays Private

Uploaded lists are encrypted, never shared and deleted automatically after 15 days.

Clean Your List in 3 Steps

Simple enough for marketers, powerful enough for developers.

1

Upload

Just upload your CSV or TXT file. We auto-detect the email column for you.

2

Verify

Our engine validates DNS, MX records, and SMTP servers without sending mail.

3

Download

Get a clean file with emails marked as Safe, Risky, or Invalid.

What happens in the background?

Your data is processed on multiple secured servers. We connect to the recipient server to check existence, analyze domain reputation, cross-reference email with our database, and perform the advanced analysis. Verification data is automatically deleted after 15 days. You can also delete verification files anytime from the Results page. Read how Reoon verifies an email address, step by step.

Frequently Asked Questions

Quick answers to common questions about email verification.

What is email verification and why do I need it?

Email verification is the process of cleaning your email list by identifying invalid, disposable, and spam-trap emails. You need it to reduce your bounce rate, protect your sender reputation, and ensure your marketing emails actually reach real inboxes.

Why is Reoon more accurate than competitors?

We perform deep SMTP handshakes and maintain a live, proprietary database of disposable email providers. Unlike basic regex checkers, we verify if the inbox actually exists without sending a real email, ensuring 99% accuracy for any mixed quality email list.

Do unused credits expire?

Instant credits never expire. You can buy credits today and use them next month or next year. Daily credits reset daily (unused daily credits don’t carry over). More about how credits work.

Is my data stored securely?

Yes, absolutely. Your data is encrypted during transfer and processing. Furthermore, your uploaded files and results are automatically deleted from our servers after 15 days of the verification. We never sell or share your data.

Can I verify difficult emails like Yahoo and Outlook?

Yes. Many verifiers struggle with Yahoo, AOL, and Microsoft Outlook (Hotmail/Live) due to their strict security. Reoon uses specialized algorithms to verify these difficult providers with high precision, minimizing "Unknown" results. Compare providers yourself with our self-testing guide.

What is a "catch-all" or "accept-all" email?

A catch-all server accepts emails sent to any address at that domain, even if the specific user doesn't exist. These are risky because they might eventually bounce or damage your reputation. Reoon identifies these so you can decide whether to keep or remove them. Read more about catch-all addresses.

How do I integrate the Email Verification API?

Integrating is simple. We provide a RESTful API that returns JSON responses. You can use our "Quick Mode" for instant checks (under 0.5s) on registration forms, "Power Mode" for deeper analysis and the "bulk endpoint" to verify a list of emails together. Full documentation and code examples are available in your dashboard.

Does Reoon detect disposable or temporary emails?

Yes, we have one of the most advanced disposable email detection systems. We identify temporary addresses in real-time to prevent fake signups and low-quality leads from entering your database.

What happens if the verification result is "Unknown"?

An "Unknown" status means the destination server was not responding at the time of the check or we could not get enough signals to determine the actual status of that email with enough confidence. We do not charge credits for unknown results. See what every status means.

Can I verify a single email without uploading a file?

Yes! Our dashboard includes a Single Email Validation tool. You can copy-paste an email address and get an instant result with full details (validity, disposable status, MX records, etc.) without needing to use the API or upload a CSV.
