Brief About SmarterMail and Office 365

SmarterMail is a professional email and collaboration platform mainly designed for businesses and service providers. It provides features like email, calendars, contacts, instant messaging, and more. Its licensing policy is a one-time purchase per mailbox, which is budget-friendly for small businesses. The interface is clean and easy to operate.

Office 365 (Microsoft 365) is Microsoft’s cloud-based productivity suite. Along with email, it offers collaboration tools like calendar, contacts, Teams, and OneDrive. Its biggest strengths are cloud storage, real-time collaboration, and built-in security features like anti-spam and anti-malware.

Even though SmarterMail is powerful, many users and businesses migrate to Office 365 for its flexibility, cloud benefits, and scalability.
