A smaller product with real demand.
THE SITUATION
Businesses with a domain and no website, or with a website elsewhere, who want professional email.
More common than people expect, particularly among small local businesses.
WHAT IT INVOLVES
A small hosting account used only for mailboxes DNS configured for mail SPF and DKIM set up properly Client devices configured
WHY IT IS WORTH OFFERING
Low resource use, so many fit in your allocation Simple to support once configured A route to a client who later wants a website
WHAT TO CHARGE
Per mailbox or per domain, modestly.
Compare against the commercial alternatives so you can explain the difference.
WHAT TO BE HONEST ABOUT
Hosting mailboxes are perfectly adequate for ordinary business correspondence.
They are not a substitute for a full collaboration suite if the client needs shared calendars and documents.
Say so rather than overselling.
THE SUPPORT REALITY
Email support is device configuration, mostly. Expect that, and produce a short guide.
THE COMMON ISSUE
Deliverability. Get SPF and DKIM right at setup and most problems never arise.
