What disposable emails are
Services like temporary inbox generators let people receive one email, such as a confirmation link, without giving a real address.
Why marketers should review them
- They inflate list size without adding real readers
- They often bounce once the inbox expires
- They can signal low-intent or abusive sign-ups
How MailGuard flags risky addresses
Disposable domains are flagged in the result details alongside other signals, like role accounts and syntax problems, so you can filter them out before you export.
Frequently asked questions
Should I always remove disposable emails?
For marketing lists, usually yes. For transactional messages, such as a receipt, you may still need to send.
