If you run events, webinars, or gated downloads, repeated registrations with the same email create confusion and inflate your numbers. A better approach is to enforce one registration per email (or per email + phone) from the start.
Why this happens
- Users try to “make sure it worked” and register again
- People share the same registration link repeatedly
- Manual spam submits the same identity many times
What most sites do wrong
- Rely only on confirmation emails
- Try to clean duplicates after they happen
- Use CAPTCHA and assume the problem is solved
The correct solution: unique registration fields
Prevent duplicates by blocking repeat submissions using email as a unique identifier. This keeps registration counts accurate and stops duplicate attendee records before they exist.
Recommended setup
- Unique: email (minimum)
- Optional unique: phone (stronger identity check)
- Clear success message or thank-you page
Accurate registrations begin with uniqueness, not cleanup.
