Why Should You Care?

Disposable Email Addresses (DEAs) are temporary, throwaway email addresses that are typically used by individuals who choose to hide their identities. Most of the time, these email addresses have a short life span like 10 minutes - enough to open and click the link in your verification email to confirm that the address is valid. In a commercial context, as an online merchant or service provider, you might want to be careful about potential customers entering your service using temporary email addresses (as those provided by Mailinator, YOPmail, GuerillaMail, 10MinuteMail, MailDrop, etc.). The use of Disposable Email Addresses in a commercial relationship must be avoided because:

  • Usually, it indicates a lack of trust in your company or brand. Trust is the foundation of the commercial relationship between buyer and seller.
  • They might want to take unfair advantage of your service or offers, like a discount or free trial or possibly even payment fraud.
