[03] Why Verify Emails
Protect your sender reputation
Reduce Bounce Rate
Invalid emails bounce and hurt your sender score. Verify before you send to keep bounce rates under 2%.
Improve Deliverability
A clean list means more emails land in the inbox instead of spam folders.
Save Money
Stop paying to send emails to addresses that don't exist or will never convert.
Protect Your Domain
High bounce rates can get your domain blacklisted by email providers.
Better Analytics
With verified emails, your open and click rates reflect real engagement.
Detect Spam Traps
Identify risky emails before they flag your campaigns as spam.
[04] FAQ
Frequently asked questions
How many free email verifications do I get?
You get 5 free email verifications per day. Your limit resets every 24 hours. For unlimited verifications, sign up for a RevoScale account starting at $49/month.
What does the email verifier check?
We check email format, domain validity, MX records, SMTP response, mailbox existence, catch-all detection, disposable email detection, and role-based email detection.
What is a catch-all domain?
A catch-all domain accepts all emails sent to any address at that domain. This makes it impossible to confirm if a specific mailbox exists, which is why we flag these as risky.
Why are disposable emails marked as risky?
Disposable emails are temporary addresses that expire quickly. Sending to these addresses often results in bounces and can hurt your sender reputation.
Can I verify emails in bulk?
The free tool supports single email verification. For bulk verification (up to 100,000 emails per file), sign up for a RevoScale account.
