Frequently Asked Questions

1. How fast is a single email check?

Most checks return in just a couple of seconds, a real-time SMTP-level validation runs instantly with no queue or file to wait on.

2. Does real-time verification work the same as bulk verification?

The underlying check is the same SMTP-level validation used across ReachStream Email Verifier, but real-time verification checks one address instantly with no upload, while bulk verification processes a CSV file of many addresses at once. Use real-time before a single send, and bulk when you’re cleaning a full list.

3. How many credits does one check use?

One credit verifies one email address, whether checked in real time or as part of a bulk upload.

4. Can I check an email without creating an account?

Yes. You can verify an email for free without creating an account; the Free Trial simply gives you 100 credits and saved results if you sign up.

5. Why verify an email before sending instead of after?

Sending to an invalid or risky address after the fact still counts as a bounce or spam complaint, which can hurt your sender reputation. Verifying beforehand catches those addresses before they ever reach your send, protecting deliverability instead of repairing it afterward.
