Mail guides

Add the domain you want to send from. You'll be shown the DNS records to add at your registrar — typically MX records so mail for your domain is delivered to Triostack Mail, plus authentication records (SPF, DKIM, and DMARC) that prove messages really come from you and keep them out of recipients' spam folders. DNS changes can take a while to propagate, so verification may not be instant.

Create an individual mailbox for each person. Mailboxes are tied to TriostackOne identity, so each person uses the same account they use for every other app, with single sign-on and shared roles — and removing someone from the workspace removes their mail access too.

On Starter and above, create shared inboxes for team addresses such as support@, sales@, or billing@. The team can assign emails to a teammate, snooze them, resolve them, and leave internal notes — instead of forwarding threads around or replying twice.

If you're moving from another provider, plan the switch so nobody loses history: create the mailboxes first, bring over existing email, and switch your MX records last so no incoming mail is missed during the move. Contact the team for help planning a company-wide migration.

On Starter and above, book meetings and share availability without leaving your inbox or switching to a separate calendar app.

On Business and above, the CRM context panel shows the sender's CRM record, open deals, and support tickets next to every email — so sales can reply to a prospect with the deal in front of them, and support can see an account's history before answering.

Connect a shared inbox such as support@ to Triostack Desk and inbound emails become tickets automatically, with SLA tracking and escalation. Built-in spam, phishing, and malware filtering protects every mailbox.
