About this tool
A web-based POP3 client for reading email. Point it at any POP3 server (Gmail, Outlook, your own server) with host, port, TLS mode and credentials, then read the most recent messages in the inbox — sender, subject, date and the message body. POP3 has no folders, so the whole mailbox is one list. Great for testing POP3 credentials and TLS settings or checking what's waiting on a server. Reads only — it never deletes messages. Signed in, you can reach private / LAN / localhost servers and save mailboxes that sync across devices — the password is encrypted at rest with AES-GCM. Signed out, the connection is one-time, public-host only, and never stored.
Frequently asked questions
Will this delete mail from the server?
No. The viewer connects, lists and reads messages, then disconnects without issuing any delete — your mail stays on the server.
POP3 or IMAP — which should I use?
IMAP keeps mail (and folders) on the server and is the modern default — use the IMAP Mailbox Browser for that. POP3 is the older, folderless protocol; use this viewer when a server only offers POP3.
Does it need an app password?
If the account has two-factor authentication on (e.g. Gmail, Outlook), yes — generate an app password in the account's security settings and use that instead of your normal password.
