Answers for fast-moving teams
Yes. You can require approval by mailbox, account, intent, or keyword, then keep the full thread summary visible before a reply is sent.
Bring your own. You connect an existing Gmail, Outlook, or custom-domain mailbox with its IMAP/SMTP details and an app password — that path is available to every workspace from day one. One-click Google and Microsoft sign-in is rolling out in stages to an approved pilot group.
Any mailbox that speaks IMAP and SMTP works, including Gmail, Outlook, and custom domains. Contact records, billing, and team access live in your wider Stackado workspace rather than being duplicated inside Zendo.
Most teams connect a mailbox, import a first campaign, and start inbox monitoring in under an hour.
Plans scale with sending volume and connected mailboxes. Book a demo and we will map a plan to your team, then add seats or domains as you grow.
