Use Data from Repository Management Platforms

Follow the below steps to use data from repository management platforms to detect disposable Emails:

Step 1: Go to a repository management platform or website. Some commonly used ones are GitHub Gist and Pastebin. Select the platform you’re most comfortable using.

Step 2: Search for a list of disposable email domains on GitHub Gist. Type “disposable email domains” into the search field and sort the results with the most recently updated ones on top.

Step 3: Search for lists of disposable email domains on Pastebin. Searching on Pastebin may be a challenge since there is no search bar. A workaround is to type pastebin.com disposable email domains on Google or other search engines.

Step 4: Determine the domain of the email address.  

Step 5: Check if the email domain is in the list of disposable email domains. From the list, search for the email domain by pressing CTRL+F (for Windows computers) or Command-F (for Macs). If you find the email domain in the database, the email address is disposable.

Step 6: Perform step 5 on multiple lists. You may need to check several sources of disposable email domains to ensure accuracy. The email domains found on these lists come from other members and are mostly from blocklist sites. As such, they may not be the most complete or updated, so it’s best to check multiple sources.

Disposable email addresses are commonly created for one-time use only. People often utilize them to sign up for accounts to avoid getting too many marketing emails in their official email inboxes. Several disposable email domain providers offer addresses that can only be used for a specific amount of time.

While disposable or temporary email addresses are useful for privacy protection, businesses may need to find ways to detect them. Suppose you own a software-as-a-service (SaaS) business that operates on a freemium model. You may want to detect disposable email addresses and encourage users to sign up with their official ones instead. That way, you can reduce the likelihood of freemium abuse, as well as ensure you can reach users via email. Otherwise, your email marketing efforts might be negatively affected. You may end up with a high bounce rate and low conversion rates.
