RelyPost vs Microsoft 365: business email comparison
Microsoft 365 Business Basic includes business email and web and mobile productivity tools. Teams availability depends on the offer. RelyPost provides an independent email workspace with IMAP, SMTP, CalDAV and CardDAV support for compatible clients.
Check whether you need the Microsoft ecosystem or primarily need email that works in your chosen client.
RelyPost is a business email service for small businesses and teams, operated by Digital Shift LLC. It provides email on a domain you own, calendars, contacts, files and team administration, with an Arabic and English interface.
When RelyPost may fit
Consider RelyPost when you want domain mailboxes, shared addresses on eligible plans and team administration without adopting a full office suite. Test the protocols your exact Outlook version or other email client supports.
When the other option may fit
Consider Microsoft 365 when your team relies on Exchange workflows, OneDrive and Microsoft productivity apps. Compare specific licenses rather than assuming every plan includes desktop Office.
What to test before choosing
Do not equate IMAP access with full Exchange compatibility. Test shared access, calendar invitations, contacts and delegated sending on real devices. Keep the cost of any separate office licenses in the total.
Compare the real cost
Use the current RelyPost plans and the provider’s official offer for your region. Count personal and shared mailboxes, storage, domain costs, taxes, renewal terms and any separate apps you still need. Prices and features can vary by plan; this comparison does not claim that RelyPost is always cheaper.
View RelyPost plansBefore you move your email
Inventory mailbox rules, archives, aliases and resource calendars separately. Confirm which items the selected import method moves. Pilot a single mailbox before changing MX records, and keep historical exports and the old service available through verification.
Is RelyPost always the cheapest option?
No. The total depends on mailbox count, storage, billing terms and other applications your team needs. Compare current plans and renewal terms for the same requirements.
Can I keep my domain when switching email providers?
Yes, if you control the domain and its DNS. Domain registration and email hosting are separate. Verify domain ownership, prepare the destination mailboxes, and change the required mail records after testing the migration. Keep the old service available until the move is verified.
Try your actual workflow.
Start with a domain and a small group of users. Check mailbox allowances, test your email apps and confirm shared access before moving the whole team.
