Best Practices

1. Provide Immediate Feedback

Show validation status as form is filled:

<form>
  <input type="email" id="email" placeholder="your@email.com" />
  <div id="email-status"></div>
</form>

<script>
document.getElementById('email').addEventListener('blur', async (e) => {
  const email = e.target.value;
  const result = await verifyEmail(email);

  if (result.status === 'valid') {
    document.getElementById('email-status').innerHTML =
      '✓ Valid email';
  } else {
    document.getElementById('email-status').innerHTML =
      '✗ Invalid email';
  }
});
</script>

2. Don't Block Form Submission

Show warnings instead of preventing submission:

const handleSubmit = async (e) => {
  e.preventDefault();
  const email = formData.email;
  const result = await verifyEmail(email);

  if (result.status === 'invalid') {
    showWarning('This email address may not be valid. Continue?');
    // Let user choose to proceed
  } else {
    submitForm();
  }
};

3. Handle Unknown Results

Some emails can't be definitively verified:

if (result.status === 'unknown') {
  showMessage('We couldn\'t verify this email. Please double-check.');
  // Don't reject—let user decide
}

4. Monitor Submission Quality

Track these metrics:

• % of valid emails
• % of invalid emails
• % of unknown emails
• % of disposable emails
• Typical response count

5. Use for Lead Scoring

Incorporate email validity into lead scoring:

let score = 0;
if (emailVerification.status === 'valid') score += 10;
if (!emailVerification.result.disposable) score += 5;
if (emailVerification.result.smtp_valid) score += 5;

Example Implementations

Typeform with Webhooks

// Your webhook endpoint
app.post('/webhooks/typeform', async (req, res) => {
  const email = req.body.form_response.answers
    .find(a => a.type === 'email')?.email;

  const result = await emailverify.verify(email);

  if (result.status === 'invalid') {
    // Optionally: create task for invalid email
    notifyTeam(`Invalid email in form: ${email}`);
  }

  res.json({ success: true, verification: result });
});

Google Forms with Apps Script

function onFormSubmit(e) {
  const responses = e.response.getItemResponses();
  const email = responses
    .find(r => r.getItem().getTitle() === 'Email')
    ?.getResponse();

  const result = UrlFetchApp.fetch(
    'https://api.emailverify.ai/v1/verify',
    {
      method: 'post',
      headers: { 'Authorization': `Bearer ${API_KEY}` },
      payload: JSON.stringify({ email }),
      muteHttpExceptions: true
    }
  );

  const verification = JSON.parse(result.getContentText());

  // Log to sheet
  const sheet = e.source.getSheetByName('Responses');
  sheet.appendRow([email, verification.status]);
}
