Emails are a means of communication, and enterprises cannot afford the risk of getting important client emails being buried under endless threads, missing deadlines because a message never syncs, and security scares that keep IT up all night. 

These issues typically arise when enterprises rely on outdated on-premise email hosting or generic consumer-grade email software that lacks the scalability, security, and integration modern businesses need.

However, with an enterprise email service provider, everything from the infrastructure and security to updates and management is handled for you. You need to simply focus on using it. 

As an enterprise, if productivity is suffering due to outdated systems, syncing issues, or security risks, it’s time to switch to a modern enterprise email service provider that ensures seamless communication, stronger protection, and effortless scalability. Let’s understand more about enterprise email service providers and the best picks for your business.

Enterprise email is a business-grade email service that is developed specifically for organizations that need secure, reliable, and scalable communication across teams and departments. An enterprise email provides more control and flexibility over the email resources as compared to a generic email. 

Unlike free or generic email accounts, an enterprise email plan offers businesses: 

• Custom domain, like yourname@companyname.co.site, for personal branding
• Advanced security features, like encryption, 2FA, advanced antispam, and antivirus 
• Collaboration tools such as shared calendars, appointment booking, and contact directories 
• Centralized administrative to manage all the email accounts associated with the domain name 
• High availability and scalability, often backed by cloud-based infrastructure with 99.9% uptime guarantees

However, you can avail all these benefits if you choose the right email service provider. There are a multitude of options available. It becomes important to choose the right one such that you get all the features without spending extra on email management and marketing. So, let’s look at the best email service providers that you can consider as per your needs.
