When you want to sign up for an app or a website, many of them ask you to share your real block temporary email services. This is a privacy invasion, and also it may lead to sites selling your information or sending you unwanted emails. For this reason, a lot of people use disposable and temporary email services to hide their personal email addresses from sites and apps.

Disposable email services are quick and easy to use. They hide your identity and allow you to signup for websites or apps without revealing your real email address. These services delete your email address and inbox content within a set time frame (for example, Maildrop destroys emails after 48 hours while 10minutemail destructs them within minutes).

Closing the Gate: Strategies to Block Temporary Email Services and Prevent Abuse

This makes them very useful for users who want to sign up for multiple services or apps. But, for email marketers, they can be a nuisance because they will not get their legitimate emails delivered. This is because most of the time, the disposable email addresses are invalid.

To avoid getting blocked at an ISP, it is best to monitor the validity of all your disposable and temporary email addresses regularly. This can be done by using a real-time email verification API. The service will keep a track of all the new disposable and temporary email providers and check new addresses against it.

Aside from the email verification API, another great way to monitor the validity of your subscribers is by asking them to confirm their registration and interest in your products or services every once in a while. This will help you identify the fake and invalid addresses in your list.
