I am using zoho for email purpoae only. I hame more than 15 websites and Every months it’s growing. I am developed own websites and also client’s. But when I ho for hosting email service clients are not setisfy with this. They need simple and user friendly but not ready to pay for this. Paid email services are good but zoho help to go with them free of cost with maximum 25 free email acvounts. It can be extend by pay or refer to others.
Zoho help me to connect with my domain name and create email acvounts and access in desktop, mobile and apps.
Easy to configare with domain. You just need some knowledge but you can do this by user manual.
You can control all users.
Zoho’s others products also good. But I have only experience on Zoho mail service.
