A disposable email is an email address service that allows registered users to receive emails at a temporary address. Emails sent to disposable email addresses expire after a certain period of time. Disposable email accounts enable users to sign up and verify registration with various companies without exposing their primary email address to spam. Disposable email addresses are also referred to as burner emails, due to their self-destructing nature.
Disposable emails have the ability to dramatically affect the domain reputation of small to midsize businesses. When a company sends marketing emails to a large amount of email addresses, their bounce rate will increase. If a company's bounce rate gets too high, email address services may mark the emails sent out as spam, severely affecting a company's email marketing success rate. To avoid sending emails to disposable email addresses businesses should use an email verification solution or cross reference disposable emails with an online disposable email domain database.
