Users validation

Validate users

If your site suggests that users should register before being granted access to certain content, a few disposable or fake email addresses are likely to end up on your list, as users often like to try and circumvent this process. Ensure that only valid email addresses are accepted.

Reduce risks of free-tier abuse

If you offer a free plan, users may attempt to abuse it through disposable email domains.

Keep churn rates low

Those who sign up with throwaway email addresses are far more likely to add to your SaaS churn rate than those who use regular email addresses.
