Verify every email before it costs you a bounce
Real-time and bulk email verification that catches typos, disposable addresses, and risky domains, with a confidence score you can act on.
What Powers RelayVerify's Engine
A look into the validation infrastructure behind every address, so you can send faster, smarter, and with confidence.
Single verify for one-off checks, bulk verify for lists of any size, submitted as an async job you poll for completion.
Every address passes through a 7-stage validation pipeline with early termination: syntax, disposable check, DNS/MX, domain reputation, SMTP handshake, mailbox intelligence, and risk scoring.
Every result includes a 0-100 risk score, a status, and, when we catch a likely typo (like gmial.com), a suggested correction.
Everything you need to keep your list clean
Verification is the core but the platform around it is what makes it usable at scale.
Single Verify
Check one address in real time, from the dashboard or the API. Get a result in under 3 seconds.
Bulk Verify
Submit a list of any size as an async job. Poll for progress, then download results as a file, built for lists that don't fit in a single request.
Risk Scoring
A weighted 0-100 score built from all seven pipeline stages, plus a clear status: deliverable, risky, undeliverable, or unknown. One number to set your send threshold against.
Suppression Lists
Bad and bounced addresses are tracked automatically, so you don't re-verify or re-send to the same dead address twice.
Bounce Feedback Loop
Report real-world bounces back into RelayVerify, individually or in bulk, and future results get sharper over time.
History, Export & Per-Key Accounting
Every result is logged and searchable by date or address. Export anytime, and issue separate API keys per client or campaign to keep usage cleanly separated on your dashboard.
Pricing that scales with your list
Every plan includes the full 7-stage pipeline and every feature above. You're paying for volume, not features.
Credit limits reset on the first day of each calendar month.
Score and Clean Your Lists
Every email that goes through RelayVerify runs through a 7-stage pipeline with early termination, so obvious bad addresses get rejected fast, and only ambiguous ones get the full check.
What We Check (7-Stage Pipeline)
Every address you verify with RelayVerify runs through all seven stages below, with early termination, so a failure at Stage 1 skips the rest and returns fast.
We catch invalid email formats, typos, and structural errors, so you never lose a good lead over a misplaced dot or missing "@".
Checked against a database of 30,000+ known disposable and temporary email domains, kept current on a weekly update cycle.
We confirm the recipient's domain has a properly configured mail server. No valid MX record, no send.
Some domains accept any address format but silently drop the message. We test for this directly and flag catch-all domains so you can decide how to handle them.
We check the domain against known spam and abuse indicators, including newly-registered and parked domains, to protect your sender reputation before you send.
We verify mailbox existence directly at the mail server without sending an email. Servers that respond with a temporary rejection (greylisting) are automatically retried after a delay instead of being marked invalid.
We identify role-based addresses (like info@ or support@) and free email providers (Gmail, Yahoo, Outlook), then combine every signal from all seven stages into one weighted risk score.
Check Before You Send

Enterprise Controls
Built for teams running verification at scale, not just one list at a time.
Cap credit consumption per API key, per product, so no single integration can blow your monthly budget.
Assign different rate limits to different keys: staging vs. production, or client vs. client.
Rotate a key's secret without downtime, or set an explicit expiry. Enterprise-tier keys default to one year.
