Frequently Asked Questions

Have questions about Mailmeteor's Email Verification feature? Find answers to common queries below.

Why should I verify email addresses?

Verifying emails ensures that you’re reaching real, active inboxes. This helps you:

Avoid bounce rates and spam traps
Protect your sender reputation
Improve deliverability for your campaigns

With Mailmeteor’s BounceShield, you get fast, secure, and accurate validation to help maintain a healthy email list.

How does Mailmeteor verify emails?

Mailmeteor uses a multi-step verification process through BounceShield. We check:

Email format
Provider trustworthiness
Domain existence and operability
Mailbox availability

These checks ensure that your email list is clean and safe to use.

What do the verification results mean?

Each email is categorized as:

Valid – Safe to send to.
Invalid – The address doesn’t exist or is misconfigured.
Risky – May accept mail but could bounce.
Unknown – Could not verify due to temporary issues.

Can I upload a list of emails to verify?

Yes, you can upload a CSV or import from Google Sheets. Mailmeteor automatically scans and cleans your entire list in one go.

Is there a limit to how many emails I can verify?

Mailmeteor offers flexible plans:

50 free verifications/month
Pay-as-you-go for occasional checks
Scalable monthly plans starting at $24/month

See the pricing page for full details.

How long does email verification take?

Most emails are verified in less than a second. Large lists are processed efficiently, and results appear instantly in your dashboard.

What happens if an email fails verification?

Invalid or risky addresses will be flagged, and you can exclude them from your campaigns. The dashboard also shows the reason for failure so you can understand the issue.

Can I integrate email verification into my app?

Yes. Not yet, but Mailmeteor will soon offer a powerful Email Verification API so you can:

Integrate into sign-up forms or CRMs
Automate bulk verification workflows

Is email verification included in all plans?

Email verification is included in all paid Mailmeteor plans and available on a pay-as-you-go basis. Visit our pricing page to choose what’s right for you.

Will verification emails appear in my sent folder?

No. Unlike warm-up emails, verification is a passive process that checks the validity of addresses without sending messages.
