Per mailbox

Business Mailbox

One mailbox on your domain, authenticated so it arrives.

What this tier is

A mailbox on your own domain is the cheapest credibility a small business can buy, and it stops being credible the moment mail lands in spam. The work is in the DNS: a correct SPF record, a published DKIM key, and a DMARC policy that aligns with both.

We run Stalwart on our own infrastructure. Mailboxes are provisioned with quotas and retention agreed in advance, and we verify authentication end to end before handing over, including sending test mail and reading the results.

  • Migration from an existing provider by IMAP sync

  • A second mailbox for a specific function or contract
  • Replacing a mailbox bundled with a hosting account you are leaving

Responsibility split

Written down so there is no argument about it later.

We handle

  • Mail server operation, patching, storage, and TLS
  • Authentication records and delivery verification
  • Aliases, filtering, quota, and retention configuration
  • IMAP migration from your previous provider

You handle

  • Publishing DNS records, or delegating the zone to us
  • Your mail client configuration on devices you control
  • Keeping your own archive if you need mail beyond the agreed retention

How provisioning works

Operator-provisioned. Mail requires DNS changes on your side, so setup is a short back-and-forth rather than an instant switch. Typical turnaround is one to two business days once records are published, longer if a migration is involved.

Order

Billing period

We use this for the invoice, provisioning updates, and account sign-in.

The domain the mailbox should live on.

For example hello@yourdomain.com.

Migration deadlines, existing stack, constraints.

Payment is handled by Stripe. We never see or store card details. Continuing means you accept the Terms, Acceptable Use Policy, and Privacy Policy.
