I love how it's easy for me as an admin, or even just someone who doesn't know anything about tech stuff at work but needs them set up correctly! It was so simple that my boss asked if we could use their service because he didn’t want us having another system in our office (we were using Outlook).
The only thing is you need some knowledge - not too much though since they have tutorials online which are very helpful when setting things like filters etc.. We're currently trying out different services such as Zoho Mail & Gmail Inboxer by Google Apps Scripts/Apps Directory Services from Microsoft 365 Business Essentials with folder support enabled through PowerShell cmdlets. This has made managing multiple accounts easier than ever before without needing any additional software / apps installed locally within each account itself!
