Frequently Asked Questions

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.

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

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

Yes. You can verify an email for free without creating an account. Sign up for the Free Trial to get 100 credits and saved results.

Sending to an invalid or risky address still counts as a bounce or spam complaint, which can hurt your sender reputation. Verify beforehand to catch those addresses before they ever reach your send, and protect deliverability instead of repairing it afterward.
