Disposable email accounts are not permanent as you will find with Gmail, Outlook.com, Yahoo, etc. They are also usually anonymous email accounts, which means you can sign up without giving your name, phone number, home address, etc. You can use a disposable email address if you sign up for a user account that you will only use temporarily or if you are sure you won't even need to read the emails. For example, you'll want to avoid using a disposable address for your bank account, as you might need bank statements or access a recovery email if you've forgotten your password.
However, keep in mind that unlike a regular email service, disposable / temporary email accounts usually don't have advanced features like the ability to see when someone read your email, move emails to folders based on rules, save contacts, export messages, create funny signatures and even send emails often (most of them only allow you to receive them).
Important! Again, it is not recommended to use temporary email addresses as your primary means of obtaining email from important websites. You should use a secure account that only you have access to, such as a private email service.
If you're a 21st century company, you probably have an email marketing campaign. At this point, it's a necessity to generate leads and connect with existing customers. It has never been as easy as collecting addresses and sending messages, but lately the stakes have been raised even more.
More emails are being sent than ever and this includes spam. Increasingly, consumers have felt bombarded with spam messages, leading them to feel cautious about the people they share their information with. It makes sense on the surface, until you realize that this, in turn, has led to the proliferation of the disposable, or DEA, email address.
