The Master Inbox page in your dashboard shows your Master Inbox address, its attached mailboxes, and connection settings (IMAP host, port, SMTP) — it does not display the actual emails. Clicking into it will not open a list of messages.

To read what's arriving in your Master Inbox, you need to connect it to an email client (see below) using those same IMAP/SMTP details.

Any IMAP-capable email app works — BlueMail, Outlook, Apple Mail, or a mobile mail app. We recommend BlueMail for the Master Inbox specifically.

BlueMail setup: Add account → Manual setup (not the quick-setup box) → select IMAP → enter the mailbox email + password.

Incoming (IMAP): the host shown on your dashboard/welcome email for that mailbox, port 993, encryption SSL/TLS. (IMAP hosts are specific to each mailbox — don't reuse one mailbox's IMAP host for another.)

Outgoing (SMTP): smtp.maildoso.com, port 587, encryption STARTTLS — this is the same for every mailbox on every account.

If you're not sure which IMAP host to use for a specific mailbox, contact us and we'll confirm it.

On the Master Inbox page in your dashboard, enable the warm-up filter tag so warm-up traffic is hidden from view and you only see real replies once connected in your email app.

This only works for @maildoso.email Master Inbox addresses, not custom-domain ones.

Double-check for stray leading/trailing spaces in the email, password, host, or port fields — a common cause of failed connections.

Re-export the mailbox's credentials from the dashboard (Email Accounts → select → Export selected to CSV) rather than relying on details saved or copied earlier — they may be stale.

Confirm you're using IMAP (not POP) and the exact host/port/encryption combination above.
