Mailboxes

Create mailboxes for your team four ways: invite one person, bulk-invite a whole list, create one manually, or bulk-create many with admin-set passwords.

Send setup links to up to 500 recipients per batch — paste a list or upload a CSV, allocate storage per person, and let each user pick their own password.

Upload a CSV to create many mailboxes at once with admin-set passwords.

Manage mailboxes and pending invites with search, filter, and bulk action tools. Sort by storage, filter by type, and manage invites efficiently.

Forward incoming mail from a TrekMail mailbox to one or several addresses, with per-plan caps on Starter, Pro, and Agency and an option to keep a local copy.

Give your mailbox extra email addresses without creating separate accounts. Aliases deliver mail into the same inbox and can be used for sending too.

Step-by-step guide to adding, toggling, and removing aliases.

Open a team inbox such as support@ or sales@ from your own mailbox, with individual sign-ins and no shared password. Follow the setup steps.

Let your team send from one shared address with personal signatures. Keep customer replies in the team inbox and give each person their own sign-in.

Connect your own mailbox with an app password, then use shared inboxes you can read and send from. Learn how permissions and Sent folders work.

Change a TrekMail mailbox password, issue a fresh recovery code, and check 2FA status; everything that hardens one mailbox now lives on the Security tab.

Give each mail app or phone its own password, see when it was last used, and switch off a lost device without changing your mailbox password.

Reset mailbox passwords from the dashboard, issue self-service recovery codes, hand new credentials over safely, and force-reset during a security incident.

Change your mailbox password without admin help — three reset paths (current password, recovery code, recovery email) plus what changes on IMAP and SMTP.

Delete a TrekMail mailbox singly or in bulk — what happens to emails, aliases, forwarding, and sessions, plus pause and forward alternatives for offboarding.

How storage is counted across your account; pooled quota that combines email and Drive, what happens when you hit the limit, and how to free up space.

Switch a mailbox between shared storage and a fixed size of its own, understand the checks a new size has to pass, and automate it with the API or MCP.

Stop one person filling your shared storage with personal files. Turn Drive off for a mailbox, or leave it on only for large email attachments.

Lock someone out of a mailbox without losing their email. Sign-in stops, delivery carries on, and everything is waiting when you switch it back on.

Automatically sort, forward, flag, or discard incoming emails using mail filters. Learn how conditions, actions, and filter order work in TrekMail.

Step-by-step guide to creating, editing, reordering, and deleting mail filters.

Set up conditional mail filters to forward only specific emails — by sender, subject line, or message content — rather than forwarding everything.

How to enable and configure automatic out-of-office replies.

Use practical mail filter examples to forward invoices and sort newsletters. Follow each recipe to choose matching conditions and actions.
