> **匿名ユーザー** | *2026年1月18日* | 教育管理 | おすすめ評価：10.0/10
> 
> **良いポイント**: It gets the job done. The automatic bucketing is helpful and I almost never get any spam. I feel confident using gMail.
> 
> **改善点**: I'm running up against my storage limit for Google and they will disable email functionality if I don't rectify the problem in 29 days. For all the AI tools Google is pushing, deleting old junkmail would ben appreciated tool.
> 
> I still use gMail, and probably won't switch. It's such a hassle to switch email addresses, so it would take something very big for me to leave gMail.

> 
> **改善点**: The free storage can fill up quickly if you receive many emails with attachments. Some advanced features require a Google Workspace subscription, but the free version still offers excellent value.
> 
> My overall experience with Gmail has been excellent. It is dependable, secure, and easy to access from any device. The clean interface, strong search functionality, and integration with other Google services help me stay organized and productive every day.

### "So far the best email service I experienced" — 5.0/5

> **Samuel** | *2026年7月9日* | デザイン | おすすめ評価：10.0/10
> 
> **良いポイント**: I been using gmail for since they started.I love how it's very organized with splitting categories, keeping spam seperated from inbox and if spam mail does go to your inbox you have an icon that saids report spam and goes to spam folder. I love you have an option to delete alot of emails at once instead of going through every single email to delete it . Overall very well organized setup.It's free so value is very valuable. Still never had a problem with customer support on this part of google. Interface is very easy to get around . You also can customize it with adding your own special folders for important files.
> 
> **改善点**: what I don't like is sometimes good mail goes to spam not very often but sometimes get's sent there if it's first getting the email from a place. I also don't like sometimes you report spam and they still find a way getting into the inbox mail.
> 
> My overall experience I love gmail for one they been around alot of years and with user like you and I help form it into a better email service with any problems we report it helps google to make it better and more secured I haven't had any problems besides what I mentioned overall I love it.

### "Gmail user" — 3.0/5

> **Justice** | *2026年5月4日* | 教育管理 | おすすめ評価：6.0/10
> 
> **良いポイント**: I appreciate that Gmail is a part of the Google Workspace, which makes it easier to collaborate with others. I like that you can save documents and images to your storage quickly. I like the email suggestion to follow up or unsubscribe. I like that you can tag or assign items to people in the email.
> 
> **改善点**: The filtered operations could be better within the system. We can create rules to better organize emails. It could prioritize filtering spam/phishing emails better.
> 
> I've used Gmail since I was old enough to have an email. I love the simplicity of Gmail, but a few features are missing. Overall, I like Gmail and will continue to use it.

### "My go-to for keeping my busy day organized" — 5.0/5

> **Kira** | *2026年5月17日* | 情報技術、情報サービス | おすすめ評価：10.0/10
> 
> **良いポイント**: I love how easy Gmail makes it to keep my life sorted. I get a ton of emails every day for work, school, and personal stuff, and Gmail does a fantastic job of separating the important messages from the junk mail. My favorite thing is how well the search bar works. If I need to find a specific message or a file from weeks ago, I can just type in a couple of keywords, and it pops right up instantly. Plus, it connects perfectly with Google Docs, so I can open files and work on them without any hassle. It's just really reliable and easy to use on both my phone and computer.
> 
> **改善点**: Sometimes, the automatic folders like "Promotions" or "Social" get a little too smart for their own good. Every now and then, an important email or a bill alert will accidentally end up in my Promotions folder, and I won't see it right away. I have to remember to check that folder manually every couple of days just to make sure I didn't miss anything.
> 
> Honestly, I’ve tried other email apps, but I always come right back to Gmail. It isn't just an inbox for me—it's how I keep track of my daily life, projects, and schedule. It’s clean, it’s simple, and it just works the way it's supposed to. I would highly recommend it to anyone who needs a reliable way to stay organized.
