Identifying disposable emails, also known as temporary or throwaway emails, are one-time use email address services that can be created instantly and disposed of at any time. These are popular amongst consumers for a variety of reasons including privacy, security and avoiding spam. They can be used to sign up for newsletters and mailing lists, comment on blogs or forums or to test the waters of new online shopping experiences.

It’s critical to understand that when consumers sign up with a disposable email, they are not trusting your business and may never convert into a paying customer. This is especially problematic for businesses who offer free trials, discounts or other promotional offers.

Identifying Disposable Emails: How to Block Temporary Email Addresses on Your Website

For the average consumer, the cost of a disposable email address is minimal – but for businesses, it can be very costly. The best way to protect against this kind of abuse is to build a brand that is trusted and provides outstanding products or services, backed up by a reputable team that truly cares about its customers.

Another important strategy is to keep your email list clean by regularly identifying and removing disposable emails. There are a few ways to do this, including using data enrichment to detect potentially suspicious email addresses or by using an email verification API or server-side application. These tools will check the domain or email address against a database of known disposable domains to determine whether it is an actual disposable email service address.
