For SaaS Companies

Email Verification for SaaS

Protect your free tier, improve conversion rates, and build a user base of real, engaged customers.

The fake signup problem

Up to 30% of SaaS signups use disposable or fake email addresses. These users never convert, abuse your free tier, and skew your metrics. Every fake signup costs you money in infrastructure, support, and misleading analytics.

Why SaaS companies use Sniffmail

Improve Trial-to-Paid Conversion

Users with real emails are 3x more likely to convert. Filter out disposables at signup.

Accurate Growth Metrics

Stop counting fake signups. Get real data on actual user growth and engagement.

Prevent Abuse

Block users creating multiple accounts with disposable emails to abuse free tiers.

Reduce Churn

Verified emails mean better communication. Users who receive your emails stick around longer.

Common use cases

Signup Validation

Verify emails in real-time during registration. Block disposables and catch typos before they become bounces.

Free Trial Protection

Require valid emails for free trials. Prevent the same user from creating multiple trial accounts.

Waitlist Cleaning

Launch to real users, not bots. Verify your waitlist before sending invites.

Onboarding Emails

Ensure onboarding sequences reach real inboxes. Better email delivery = better activation.

Easy integration

Add email verification to your signup flow in minutes.

// In your signup handler
async function handleSignup(email, password) {
  // Verify email first
  const verification = await sniffmail.verify(email);

  if (!verification.is_valid) {
    throw new Error('Please use a valid email address');
  }

  if (verification.is_disposable) {
    throw new Error('Disposable emails are not allowed');
  }

  // Proceed with signup
  await createUser(email, password);
}
