Bock disposable email signups is one of the most important things you can do to protect your platform from free plan and free trial abuse, boost email deliverability and get reliable user metrics. It also prevents bad actors from spamming your users or using their accounts to bypass fraud prevention measures.

Disposable email services are easy to use, inexpensive, and offer a range of functionality that attackers can take advantage of. They are a favorite attack tool for creating fake accounts, bypassing rate limits, and covering their tracks during attacks. Blocking disposable email domains helps mitigate the risks of these attacks, but it is not enough to stop all bad behavior. Use it as a starting point, and combine it with other signals like behavior patterns, device fingerprinting, and IP intelligence to make abuse harder without locking out real users by accident.

Blocking these emails helps prevent this behavior and improves your sender reputation, email delivery rates, and marketing campaign ROI.
