rental?Cloud?Comparison of introduction method of original domain mail

"Get your own domain if you want to do businessAs I mentioned, the benefits of using email with your own domain are huge, not only for companies but also for freelancers and sole proprietors.

This time, for those who want to get an email address of their own domain, what kind of method is there? I would like to tell you about the method and the advantages and disadvantages of each.

This time, I have not touched on how to acquire a unique domain.For information on how to obtain your own domain, see "[Google Workspace introduction method XNUMX] Let's acquire your own domain."

There are two ways to use email from your own domain

I think that it can be roughly divided into the following two types.

  • Rent a rental server
  • Use cloud services

Rental server is a method of operating by renting one server from a rental server company such as X server, core server, lollipop.

On the other hand, cloud services are methods that use the mail function of groupware such as Google Workspace and Microsoft's Office 365.

Cloud services are like rental servers, but the former and the latter have different service objectives and fee structures.

I will list the advantages and disadvantages of each.All comparisons focus on the mail function.

ー ン タ ル サ ー ー ー ー Cloud service
Prices Server unit Per user
Security SSL may not be available depending on the server high
Mail capacity (1 address) About 1-5GB 30-50GB
Web mail Easy Full functionality
Email client Available Available
Ease of introduction Requires similar IT knowledge

The biggest difference is stillDifferences between charges per server and per user.

In other words, in the case of a rental server, if you rent one server, the price will not change no matter how many email addresses you create.In cases where you need a lot of email addresses, it can be overwhelmingly cheaper than in the cloud.

On the other hand, in the case of cloud services, the charge is per user (email address), so if there are many users, the charge will be that much.

In the case of Google Workspace, if one user wants to have multiple email addresses, you can increase the number of email addresses at no additional charge.Detail is,"How to increase your Google Workspace email address for free."

Also, please note that SSL may not be available depending on the rental server. The fact that SSL cannot be used means that if you are using mail software, the mail server and mail software communication are not encrypted, so there is a risk that the contents of the mail will be eavesdropped on a public wireless LAN.

Comparison of rental server and cloud vendor

I compared cloud services with major rental server companies.

The price is compared when the contract is made annually including tax.

* The core server cannot use SSL for POP and SMTP, but it is safe because SSL can be used for Webmail.

Webmail on the rental server has only the minimum functions and is simpleis.Probably because many people use email software.on the other hand,Cloud services are premised on being used in a browser, so they have abundant functions and high quality..

It seems that they all have spam filters and anti-virus measures, but there seems to be a difference in performance between them.I'd like to investigate this in detail in the future, but as far as I've used it, Gmail's spam email filter is by far the best performer.


If it is only for normal mail use, it seems that there is not much difference in performance between the rental server and the cloud service.

However, I feel that cloud services are often selected as tools for work because the entire service is optimized for various business situations.
