Microsoft 365 alternative for small teams
Quick answer: Domailo is an alternative to Microsoft 365 for those who only need email on the company's domain. It charges per organization, from $5/month ($9/month for 5 people, versus $20.00 on Microsoft 365), with shared mailboxes, several domains and a 30-day trial after domain verification and card setup. Who Microsoft 365 suits best: Companies in the Microsoft ecosystem that need Outlook and large mailboxes.
Why look for an alternative to Microsoft 365?
Microsoft 365 and Exchange Online charge per user and offer full Outlook, large mailboxes and shared mailboxes with no extra license. Domailo charges per organization and works in the browser. For those who live in Outlook and the Microsoft ecosystem, Exchange is more complete; for those who want simplicity and a fixed price for the team, Domailo is more straightforward.
- Plan 1 requires an annual commitment.
- Whoever accesses the shared mailbox needs their own license.
- The admin center is more complex for a small company.
