A purchased mailbox arrives as a login:pass pair — login and password separated by a colon. To start using it, you connect the inbox over mail protocols. There are three, each with its own job: IMAP and POP3 for receiving mail, SMTP for sending. Let's break down how they differ and how to set up access in an email client or antidetect browser.
The login:pass format
Accounts are delivered as a string like email@domain:password. The part before the colon is the login (full address), the part after is the password. You enter this pair when configuring any protocol. Sometimes a service requires an app password instead of the main one — it is generated in the mail settings and used in place of the regular password.
Three protocols at a glance
| Protocol | Purpose | Key trait |
|---|---|---|
| IMAP | Receiving mail | Mail stays on the server, synced across devices |
| POP3 | Receiving mail | Mail is downloaded and usually removed from the server |
| SMTP | Sending mail | Used for outgoing mail |
IMAP — synchronization
IMAP keeps messages on the server and syncs mailbox state across all devices: read status, folders and labels look the same everywhere. It is the preferred option if you access one account from several clients or browsers.
POP3 — download
POP3 downloads messages locally and, by default, deletes them from the server. It suits a single client with local storage. The downside is no synchronization across devices.
SMTP — sending
SMTP handles outgoing mail only. It is configured alongside IMAP or POP3 so the mailbox can both receive and send.
How to connect in a client
In any email client (Thunderbird, The Bat!, mobile apps) the steps are the same:
- Add a new account and choose manual setup.
- Enter the login and password from the login:pass pair.
- Specify the incoming server (IMAP or POP3) and the outgoing server (SMTP) — addresses and ports depend on the provider.
- Enable encryption (SSL/TLS) on the provider's ports.
- Save and test receiving and sending a message.
Look up exact server addresses and ports in the specific provider's help. For example, IMAP/SMTP parameters differ for mailboxes in the Outlook email category and for other providers — always check the domain's documentation.
Connecting in an antidetect browser
To work with many accounts, it is convenient to bind mailboxes to antidetect browser profiles. IMAP/SMTP logic is handled by built-in connectors or external clients tied to the profile. The key is to isolate each account in its own profile and never mix sessions.
- One account, one profile with a separate environment.
- Use IMAP for synchronization if you revisit the inbox.
- Store login:pass pairs in a secure manager.
Common mistakes
- Wrong port or disabled encryption — the client won't connect.
- Using the main password where an app password is required.
- Logging in from different IPs without profile isolation.
Access and support
All accounts in the catalog ship with IMAP/POP3/SMTP access in the login:pass format. Delivery is automatic 24/7, payment in USDT across several networks or via CryptoBot, with a 24-hour replacement guarantee and 24/7 support. If you need a versatile mailbox for protocol-based connection, start with the general-purpose email category.
