1. What is email verification and how does it work?
Email verification is the process of confirming that an email address exists and can receive mail before you send to it. ReachStream Email Verifier runs a 7-layer check in under two seconds per address, testing syntax, domain and MX records, and SMTP mailbox existence, then screening for catch-all, role-based, and disposable addresses. Each address returns a clear verdict, valid, invalid, catch-all, or risky, so you send to real inboxes instead of guessing.
2. How accurate is ReachStream Email Verifier?
ReachStream Email Verifier verifies email addresses at 99.2% accuracy, monitored in real time across a rolling 30-day window. The accuracy comes from checking every address across all seven verification layers rather than relying on a single signal. Teams typically see bounce rates fall below 2% after their first list-cleaning pass.
3. What is a catch-all email address and how does ReachStream handle it?
A catch-all domain accepts mail sent to any address, so its server confirms every address whether or not a real mailbox exists behind it. Most verification tools either guess or wrongly mark these as invalid. ReachStream Email Verifier flags catch-all addresses separately and assigns each a risk score, so you decide whether to send, hold, or remove them. This keeps you from losing good contacts or risking your sender reputation on bad ones.
4. Can I verify emails in bulk with ReachStream?
Yes. ReachStream Email Verifier supports bulk verification of up to 25,000 emails per batch. You can upload a CSV, paste a list, or connect a workflow, and lists process in minutes with a detailed result for every address: valid, invalid, catch-all, or risky. Bulk verification is the fastest way to clean a list before a campaign or scrub an existing database.
5. Does ReachStream Email Verifier have an API for developers?
Yes. ReachStream Email Verifier offers a REST API that integrates into your signup form, CRM, or product and responds in under 200 milliseconds. It is fully documented and built to scale, so you can block invalid and risky addresses at the point of entry and keep your funnel clean from day one. Most teams integrate it in a single afternoon.
6. Is my data secure with ReachStream Email Verifier?
Yes. ReachStream is SOC 2 Type II certified and compliant with GDPR and CCPA. Your data is encrypted in transit and at rest, is never sold or shared, and remains yours at all times. ReachStream verifies your lists and returns them clean, keeping nothing.
7. What should I do with invalid email addresses I already have?
Run your existing list through ReachStream Email Verifier first. It separates valid addresses from invalid, risky, catch-all, and disposable ones, so you can suppress the dead addresses and send only to contacts that can receive mail. A single cleaning pass protects your sender reputation and stops you paying to email addresses that will never deliver.
8. Does ReachStream Email Verifier have a free plan, and what are the limits?
Yes. ReachStream Email Verifier offers a free plan that runs for 30 days and includes 100 verification credits, with no credit card required. You get instant results and the same 7-layer verification engine used on paid plans. When you need higher volume, bulk lists, or API access, paid plans scale with you.
