These names get used interchangeably across search engines, but they describe slightly different technical concepts. Understanding the distinctions helps you choose the right privacy tool for your workflow:
Usually describes a single throwaway inbox that receives one verification code or activation link and disappears after a short session.
The same concept from the sender's perspective: an unlinked alias address not connected to your real identity, stopping trackers from profiling you.
Single-use addresses meant to be used once and dropped, preventing unwanted marketing spam from ever reaching your personal primary email.
Covers all three and goes further. Instead of handing you one static box, it generates on-demand addresses across 30+ domains, custom usernames, parallel tabs, and developer APIs.
Clear, accurate answers about how temporary inboxes, privacy, retention, and custom addresses work.
Email Generator creates a temporary, receive-only email address on active disposable domains with no account signup required. Incoming emails and verification codes appear in the browser inbox automatically over IMAP.
No. Standard temporary addresses on shared public domains are accessible by address without a password, meaning anyone who knows or enters the same non-reserved address can view messages delivered to it. Never use a public temporary inbox for banking, healthcare, financial accounts, or confidential communications.
When you close an inbox tab, Email Generator triggers an immediate mailbox expunge for that session. Remaining messages and inactive mailboxes are cleared during periodic administrative server maintenance or according to optional browser auto-purge preferences, so important emails should always be saved immediately.
To reduce malware risk, binary and file attachments are stripped on disposable addresses while text and sanitized HTML message bodies—including verification links and one-time codes—are displayed inside a sandboxed preview.
Yes! Simply click "Add Mailbox Tab" to create and manage multiple parallel temporary inboxes. Each address operates independently with its own real-time inbound feed, OTP extraction, and automatic refresh.
