Detect disposable email domains is one of the most important tasks for any business that uses the email channel to communicate with users. If your business operates a freemium model, for example, you may have to deal with users abusing your service by signing up with disposable or fake email addresses. For this reason, it’s critical for businesses to detect and block these email addresses before they can damage their reputation or add to the SaaS churn rate.

To determine whether an email address is disposable, you can use a variety of tools and techniques. For instance, you can examine the length of the email and check for unusual characters or symbols that don’t usually appear in permanent email addresses. You can also check the user’s activity and see how often they’ve used the email address. In addition, you can take advantage of the Kickbox email verification and validation API, which provides real-time detection of disposable emails.
