What Are Email Addresses That Are Only Good for a Short Time?

Temporary email accounts that self-destruct after a set amount of time or after being used are called disposable email addresses.

Features:

• Short life span
• Often used without proof of identity
• Not able to be tracked back to the user

Why do people use temporary email addresses?

• Concerns about privacy: To avoid spam or protect personal info.
• Getting around limits: To access content or deals more than once.
• Anonymity: Doing things without revealing identity.

Other Costs
