❓ Frequently Asked Questions (FAQ)
1. Does this work inside my compose window?
Yes — Qverio is the only email verifier Chrome extension that works directly inside your compose window. As soon as you add a recipient in Gmail or any webmail, a verification badge appears instantly.
2. Can I verify email addresses before sending emails in Gmail?
Yes. Qverio lets you verify email addresses in real time before sending emails in Gmail and other webmail clients. This helps you avoid bounces and improve email deliverability.
3. Is this an email verifier Chrome extension?
Yes. Qverio is a Chrome extension that verifies email addresses instantly while you compose emails in your browser. No copy-pasting or external tools required.
4. Does it read my emails?
No. Qverio only checks recipient email addresses (To, CC, BCC) for verification.
It has no access to your email content, subject lines, inbox, or sent messages.
5. Which email platforms does it support?
Qverio works with all major browser-based email clients, including Gmail and Outlook Web.
If you send emails from your browser, Qverio works there.
6. What is a “Risky” email?
A risky email address exists but may reduce deliverability.
This includes catch-all domains, role-based emails (like info@ or support@), or temporary email providers.
7. What is the Sendex quality score?
Sendex is Qverio’s 0–100 email quality score.
It combines deliverability signals, domain reputation, and risk factors to help you decide whether to send.
8. What happens if an email is “Unconfirmed”?
“Unconfirmed” means the mail server temporarily limits verification. You get your credit back instantly for unconfirmed results, so there’s no risk.
9. How accurate is the email verification?
Qverio performs real-time SMTP and domain-level checks to deliver highly accurate results. Some servers may restrict verification, which is why “Unconfirmed” results are safely refunded.
10. How does email verification improve deliverability?
Verifying emails before sending helps you remove invalid and risky addresses.
This reduces bounce rates, protects your sender reputation, and improves inbox placement.
11. Is this useful for cold email outreach?
Yes. Qverio is ideal for sales teams, founders, and marketers doing cold email outreach.
It helps verify prospect emails before sending and prevents damaging your domain reputation.
12. Do I need to copy and paste emails into a verifier tool?
No. Qverio works directly inside your compose window. You can verify emails instantly without switching tabs or using external tools.
13. Can I verify multiple email addresses at once?
Yes. Qverio verifies multiple recipients simultaneously across To, CC, and BCC fields in a single session.
14. What happens when my credits run out?
When your credits run out, the extension may show an “Invalid API” message, and email verification will stop working.
This happens when your account has no remaining credits or needs to be reactivated.
When you hover over the badge, it shows: “Invalid API key / no credit”.
You can easily fix this by topping up your credits or logging back into your account.
Once updated, verification resumes instantly — your account and data remain unchanged.
⚡ Send smarter. Reduce bounces. Protect your reputation.
