Bad Emails Cost Revenue
Every invalid email in your database is a ticking cost bomb. Here is what unchecked email lists are doing to your business right now.
High Bounce Rates
Invalid emails cause hard bounces, damaging your sender domain reputation with ESPs like Gmail and Outlook.
Fake Registrations
Bots and disposable email services flood your signup forms, polluting your CRM with junk data.
Poor Sender Reputation
Sending to dead or spam-trap emails gets you blacklisted, destroying campaign deliverability overnight.
Wasted CRM Costs
You pay per contact in tools like HubSpot, Salesforce, or Klaviyo. Invalid emails silently drain your budget.
Low Campaign ROI
Open and click rates tank when your list is full of unengaged or non-existent email addresses.
Spam Complaints
Role-based emails like info@ and admin@ are often monitored by spam teams, driving up complaint rates.
There is a smarter way to manage email quality.
One API. Complete Email Intelligence.
Every validation check you need in a single, fast REST API call. From basic syntax to deep SMTP verification — we cover it all.
Syntax Validation
Instantly catch typos, missing @ symbols, invalid characters, and malformed email addresses before they enter your system.
Domain Validation
Verify the domain is real, active, and correctly configured. Detect expired or parked domains that can never receive email.
MX Record Check
Confirm the domain has valid Mail Exchange records configured and is capable of receiving emails at a network level.
SMTP Verification
Ping the mail server using SMTP handshake to verify whether the specific mailbox exists — without sending an actual email.
Disposable Email Detection
Identify 10,000+ temporary and throwaway email domains like Mailinator, Guerrilla Mail, and TempMail in real-time.
Catch-All Detection
Detect domains configured to accept all emails regardless of whether the mailbox exists, preventing deliverability surprises.
Role-Based Detection
Flag role emails like info@, admin@, support@, and no-reply@ that are shared inboxes with low personal engagement rates.
Bulk Verification
Upload CSV files with thousands of emails and receive clean, segmented results with full validation scores per address.
Real-Time Signup Validation
Inline APIIntegrate directly into your signup forms to validate emails as users type — preventing bad data at the source.
Deliverability Scoring
Risk ScoreEach email receives a 0–100 confidence score based on syntax, domain health, SMTP status, and risk signals.
Try It Right Now
