How SaaS Companies Use RocketVerifier

Signup Verification

Verify emails in real-time during registration. Block disposables, catch-alls, and known bad domains before they create accounts.

const result = await rocketverifier.verify(email);
if (result.status !== 'valid') {
  return res.status(400).json({ 
    error: 'Please use a real email address' 
  });
}
// Continue with registration

RocketShield for Forms

Add our JavaScript widget to any form. Block bad emails without any backend code. Works with any stack.

  emailVerifiedAt: null 
});

  .verifyBulk(users.map(u => u.email));
// Update or notify based on results
