Create your workspace
Sign up, name your organization, pick your plan. You're the Owner.
Invite your team
Send invitations by email. Each invitee gets a role and joins your org in one click. No shared passwords.
Connect a domain
Add your domain. We generate DNS records, or auto-sync via Hostinger, Cloudflare, or GoDaddy. Mailboxes are live in 3 minutes.
Email hosting
Everything your team needs
Bring your own domain
Connect your domain and go live in minutes. Auto-sync DNS via Hostinger, Cloudflare, or GoDaddy — or copy the MX, SPF, DKIM, and DMARC records we generate for you. Either way, you're live in 3 minutes.
Integrated Webmail
A modern webmail that works in any browser. IMAP, SMTP, TLS encryption, scheduled sending, and full trash/archiving — so you never lose an email again.
Team Workspaces
Invite teammates with one link. Assign Owner, Admin, or Member roles. Each org gets its own billing, quotas, and audit log — fully isolated from other teams.
User Management
Each user manages their own domains, mailboxes, and billing with full isolation and role-based access control.
Built for teams
Everything your team needs to ship email together
Invitations, roles, per-org billing, and an audit trail — designed for teams that take email seriously.
Email invitations
Send a magic link. The invitee creates an account on your domain in 60 seconds. Email is locked to the invite.
Role-based access
Owner, Admin, Member. Per-domain and per-organization scopes. No accidental cross-tenant access.
Per-org billing & quotas
Each org has its own plan, Stripe subscription, and email quota. Bills go to the org owner, not shared across teams.
Activity log per org
Every mailbox action is logged per organization. Filter by actor, action, or domain. Export anytime.
