Heteml hero image

heteml is a server from GMO Pepabo, Inc., known for its stability with a 99.99% uptime rate.

I recommend heteml to companies, sole proprietors, and others who value stability because:

  1. 99.99% uptime stability
  2. A separated server architecture helps avoid trouble when traffic surges
  3. Clear transfer-volume limits provide peace of mind

That is why I recommend it. I think you will be satisfied.

A competing server is ムームーサーバー . It is better than heteml in terms of domain fees and ease of domain management. Please consider it alongside heteml.

User Reviews of Heteml

Heteml received positive feedback for both support quality and speed.

However, I also found reviews about server outages. No server can completely avoid outages, but it is certainly a problem if the server keeps going down one after another.

Four Features of Heteml

Reliable Thanks to Risk-Distributed Server Operations

heteml operates by separating its servers.

  • Web server
  • Mail server
  • Database server

By separating them this way, even if one server comes under heavy load, the response of the other servers does not slow down.

For example, suppose traffic suddenly surges to the web server that displays your website. The web server comes under load and becomes a little slower. However, the mail server is not under load, so it keeps running comfortably. That means you do not have to worry about trouble such as being unable to receive inquiry emails from customers in a timely manner.

Both Transfer Volume and Storage Capacity Are Abundant

heteml offers generous transfer volume and storage capacity. It can easily handle corporate sites that tend to consume a lot of both.

Its transfer allowance is 40 TB per month. Recently, more servers have claimed unlimited transfer volume. Compared with them, this may seem small, but a clearly stated number like heteml’s actually makes it easier to use with confidence.

In fact, even if one page view consumes 3 MB, 40 TB per month is enough to handle about 400,000 accesses per day. Running out of transfer volume is extremely unlikely.

A Stable Server with 99.99% Uptime

heteml has a 99.99% uptime rate. It is extremely stable.

Problems caused by server trouble, such as a website failing to display or email being unable to send and receive, are rare. That kind of stability is exactly what matters for business use, isn’t it?

An uptime rate of 99.99% means that over a one-year contract, total server downtime stays under one hour. The rest of the time it operates without issue.

Free Phone Support

heteml offers free phone support.

It is helpful when you need assistance after checking the inquiry details but still cannot fully understand things through email support alone.

Higher Monthly and Optional Fees Are a Drawback

heteml provides business-class speed and stability, but its overall pricing is a drawback. Honestly, it is not the first server an individual should choose. It is better suited to businesses and to people who already run multiple websites.

The monthly fee falls to the equivalent of 1,210 yen on a 36-month contract, but on a 12-month contract it is 2,035 yen. Once it goes far beyond 1,000 yen, it starts to feel tough for individuals.

Restoring from backup also costs 5,500 yen each time. Many servers provide backup and restore for free, so this fee is expensive.

In any case, because it provides high-quality service, its overall pricing ends up higher, which is why it is fair to say it is aimed at businesses.

Compare heteml with Two Similar Servers

Let's compare heteml with two similar high-quality servers.

ConoHa WING

ConoHa WING is, like heteml, a high-speed server. It can be used at a lower price.

ConoHa WING is a server that lets you start a WordPress website easily. If you use WordPress Easy Setup, your WordPress website is ready at the time of signup. That is a feature heteml does not have.

Xserver

エックスサーバー is often compared with heteml. To be honest, Xserver is known for speed and stability with practically no real downsides, and it has the No. 1 market share in Japan.

Compared with heteml, Xserver's strength is that it uses a risk-distributed server architecture.

Start a WordPress Website with heteml in 7 Steps

Start Your Website with heteml!
  • STEP.1
    Visit the official heteml website

    Click “Apply with Easy Registration.”

  • STEP.2
    Enter your customer information

    Set your heteml ID, password, and email address. Once you have entered them, proceed to “Agree to the terms and move to identity verification.”

    Complete SMS verification. When the verification screen appears, enter the code you received and click “Verify and apply.”

    At this point you are still in the free trial period. Enter your contract information such as your name and phone number. Once everything is correct, click “Register” to continue.

  • STEP.3
    Sign up for the server

    During the free trial period, click “Sign up for the server” in the control panel. Choose your contract term and options.

    You can apply for the options after signing up for the server, so it is fine to leave everything unselected for now.

    The payment amount will be displayed, so proceed to “Choose a payment method.”

    Select a payment method. Credit card payment is recommended because it lets you move to the next step immediately. It also turns automatic renewal on, which helps prevent your website data from being lost because you forgot to renew.

  • STEP.4
    Get a custom domain with MuuMuu Domain and register it on heteml

    Open the official MuuMuu Domain website, enter the text you want to use as your website’s domain into “Enter the domain you want,” and click “Search.”

    You can choose a top-level domain such as “.com” or “.co.jp.” The acquisition fee and renewal fee vary depending on the top-level domain. If you are unsure, businesses should choose “.co.jp” whenever possible. Individuals are best served by “.com” or “.net.” These are familiar domains that are less likely to look suspicious and easier for visitors to trust.

    Check once again that it is the domain you want. If everything looks correct, proceed to “Go to application.”

    Create a new MuuMuu ID. Enter your ID (email address) and password, then click “Agree to the terms and move to identity verification.”

    Complete SMS verification to confirm your identity.

    Next comes the domain settings and other applications. Set the domain options as follows.

    • Public WHOIS information: Businesses should publish their information. Individuals should generally choose “Have the provider publish its information on my behalf.”
    • Name server (DNS): heteml

    If you publish WHOIS information, the name and address of the person who obtained the domain, in other words the administrator, are made public. Because that opens personal information to the public, people other than corporations or sole proprietors may prefer proxy publication.

    You do not need to apply for linked services, optional services, or MuuMuu Mail. If a business wants to use email, it can use the email service already available on the heteml server you just signed up for.

    Pay by credit card or another method. Click “Next step,” ignore the ads, and enter your user information. Once your name, address, and other details are correct, proceed to “Next step.”

    Review the application details, check “I agree to the terms of use,” and click “Acquire.” You have now obtained the domain.

    Return to the heteml control panel. Register the domain you acquired at MuuMuu Domain so that it can be used on your heteml server.

    Click “Set a custom domain.” Then click “Set a custom domain” under the displayed “New Domain Settings.”

    Enter the custom domain you acquired at MuuMuu Domain and click “Check custom domain.” If you see the message “The entered domain can be configured on heteml,” click “Register custom domain.” That completes the custom domain setup on heteml.

  • STEP.5
    Install WordPress

    In the heteml control panel, click “Easy Install” under “Various settings.” Then choose “Go to the installation screen” for WordPress.

    Enter your WordPress information.

    • Installation URL: Select the domain you obtained earlier
    • Database: Generate automatically
    • Site title: Anything is fine, because you can easily change it later
    • Username: Anything is fine, but changing it later is cumbersome
    • Password: Make it as complex as possible; it can be changed easily later
    • Email address: Your normal email address. For businesses, the website administrator’s business email is recommended
    • Privacy: Check it if you want to publish the site right away. Leave it unchecked if you want to publish after the site is complete. You can change it easily later

    The username and password are used to log in to WordPress, so be sure to write them down.

    When you click “Install” with the above settings, a message appears saying, “The folder to install into does not exist. Would you like to create this folder?” Click “OK.”

    Once the installation is complete, click the displayed URL and log in.

  • STEP.6
    Initial WordPress settings

    On the displayed WordPress login screen, enter the username and password you set during installation and click “Log In.”

    If you see a warning saying “This site can’t be reached,” the DNS settings have not propagated yet. All you can do is wait, so try logging in again every few hours.

    After logging in to WordPress, set your permalinks. In the WordPress admin screen, go from “Settings” to “Permalinks.” Choose “Post name,” then click “Save Changes.”

    When you choose “Post name,” you can enter any string you like in the URL when publishing an article. A short string that helps readers imagine the content is easier to read, which is why it is recommended. If it is too long, some people may start to wonder whether the site looks unsafe.

  • STEP.7
    Install plugins

    Go back to the WordPress admin screen, open “Plugins,” and proceed to “Add New” to install the plugins you need.

    When you find the plugin you want through search, click “Install Now” and then “Activate.” After that, follow the instructions for each plugin.

    Be sure to install security and backup plugins.

    Once your plugins are installed, your WordPress website setup is complete.
