Another option is to use a cloud-based email server hosting service, such as Google Workspace, Microsoft 365, or Zoho Mail. These services offer you a hosted email solution that is scalable, reliable, and secure. You don’t need to worry about the hardware, software, or maintenance of your email server. You also get access to other productivity and collaboration tools, such as calendars, contacts, documents, and chat. However, you also have to pay a monthly or annual fee per user, and you have less control over your email data and settings. You also have to trust the service provider to protect your privacy and comply with the email regulations and standards in your region.
