Although temporary or disposable email addresses are helpful for protecting privacy, organisations might need to figure out how to identify them. Imagine you are the owner of a freemium software-as-a-service (SaaS) company. It could be a good idea to identify bogus email addresses and urge people to register using their real ones. In this manner, you can guarantee that consumers may be contacted via email and lessen the possibility of freemium abuse. Otherwise, your email marketing campaigns may not be as successful. Low conversion rates and a high bounce rate could be the result.

2. Select a supplier whose data is up to date.
