Email is one of the primary channels every company uses to communicate with employees and customers, no matter how modest their web presence is.

Software and services run via the Internet (and not on the local computer) are called Cloud Computing. You don't need to own and operate a data center or any other computing infrastructure, as Cloud Services provide many in-built services per your requirements.

The services include a Cloud mailbox provider and a Cloud email sending service for email-related work.

Cloud mailbox providers

It is for business workflow; here, «cloud email» stands for cloud email hosting and user management. Employees can access data via mail to clients from any place allowing for improved collaboration and enhanced flexibility. In addition, cloud email hosting and service providers assist your company in connecting its internal and external resources and allowing it to withstand mail server disruptions without suffering financial losses.

Cloud email sending service

The cloud-based email services are for email automation and functionality development. It provides bulk email sending with an enhanced emphasis on deliverability, tracking, and analytical tools for scaling your business needs.

Email Client is a cloud-based provider. It is for personnel use. Email clients running on a cloud-based email infrastructure lets you own an individual mailbox, sending and receiving emails at any time. For example, your Gmail or Yahoo email account uses cloud email, while your emails are sent, managed, and stored on remote servers.

Difference between Cloud email providers and Cloud email services

Cloud (email) mailbox provider:

Cloud mailbox provider offers email client cloud services. It also aids us with add-on features and backend technologies. We pay to avail of these services together.

Cloud email sending service:

Here you pay for being managed in the Cloud. This service delivers the toolkit for automated email sending. Computing operations for this service take place in the Cloud and run on the remote server clusters.

Difference between Cloud hosting and In-house/on-premises hosting:

To choose the right email hosting solution, consider security requirements, Financial capacities, and Technical resources.

In-house hosting:

In-house hosting is building its email infrastructure and set email hosting on-premises. But using a corporate email server is quite expensive.


  • Control over data and setup
  • Small scale and long-term use is affordable
  • Doesn't rely on the Internet for accessing data


  • It needs more physical space and money for maintenance
  • Business is hampered during server breakdown

Cloud hosting:

The Cloud itself is a dynamic pool of resources providing multiple physical servers. Cloud hosting is done in virtual spaces with fewer expenses.


  • No expense for setup and maintenance
  • Greater usability
  • access to data from any place
  • No disruptions even if a server fails


  • No customizations
  • Needs Internet to access data

Considering both the services' pros and cons, we acknowledge that using cloud email hosting is a better option budget-wise. It provides online archiving with easily accessible 5 to 10 years of backup. In addition, the Cloud offers web, domain, and hosting packages in one deal and multiple mailboxes.

Google workspace(former G suite), Office 365, Microsoft Outlook, Rackspace, Zoho Workspace, ProntoMail, Tutanto, etc., are the best cloud email providers for business needs.

MailSlurp, Sendgrid, Mailgun, Mailchimp, Amazon SES, PostMark, and Sendiblue are the top cloud email sending services.

The selection of the cloud services can be as per your work requirements and budget. However, for almost all enterprises, small and large, cloud email has many opportunities, all technical tools, and security.
