## レビュー

### "A good software but with some flaws" — 4.0/5

> **Alexandra** | *2021年6月30日* | マーケティング、広告 | おすすめ評価：8.0/10
> 
> **良いポイント**: I like the fact that Mailjet has a very clear UI- and it is easy to find and craft new campaigns. They have also been one of the very first email systems to be GDPr compliant- and hence on my radar for very long. We had an account since 2019, but only recently started to consider automating our emails. The trial limit for daily emails is generous too.
> 
> **改善点**: However, there are some issues. Connecting our domain was problematic, and email automation is only available to premium users. This should be available to free users as well, maybe limiting the free daily emails at the same time. It takes time to think automation processes through, and 30 days trial might be too little to decide whether the system is right for a user or not. I at least take time to properly test a software.
> 
> So far, given we can fix the issues in connecting to our custom domain, we are satisfied. With some reservations mentioned above.

### "Good service" — 5.0/5

> **Gareth** | *2025年9月10日* | 保険 | おすすめ評価：8.0/10
> 
> **良いポイント**: Easy to use layout, good support, good content around helping to be successful, I like the UI as well
> 
> **改善点**: Email deliverability could be addressed more in teh flow of creating campaigns to help get them in to inbox
> 
> I like the service it is better value than my previous one and I am seeing some good usage out of it

### "Mailjet is a Nightmare for Small Startups – Avoid at All Costs" — 1.0/5

> **Bertrand** | *2026年3月19日* | 消費財 | おすすめ評価：0.0/10
> 
> **良いポイント**: What I liked most about Mailjet is that the platform is relatively easy to use, even for a small team without advanced technical skills. The interface is fairly simple and allows you to create and send campaigns without too much difficulty. Pricing is also reasonable compared to some competitors, which can make it attractive for small businesses at first.&#10;&#10;However, beyond that, there is nothing particularly outstanding. The features are quite standard and do not really differentiate Mailjet from other email marketing tools on the market. Overall, it does the basics, but without bringing any real added value compared to similar solutions.
> 
> **改善点**: What I liked least about Mailjet is the lack of reliability and the way accounts can be blocked without any prior warning. This creates a very risky situation for a business, especially when email communication is a key part of your activity. Decisions seem to be based purely on technical criteria, without any real understanding of the business context or human review.&#10;&#10;This makes it impossible to build a stable medium- or long-term strategy. Even with clean contact lists, strong engagement, and proper consent from recipients, there is no guarantee that your account will remain active. On top of that, customer support is extremely slow, which only makes the situation more frustrating when issues occur.
> 
> We are a tiny startup with only 10 employees, and we used Mailjet for 2.5 years. Let me tell you, it was a complete disaster.&#10;Twice, our account was blocked for over a week with ZERO warning. Why? “Technical reasons.” No human review, no consideration of our business. We only send newsletters and catalogs to clients or contacts who explicitly opted in, yet Mailjet still decided we weren’t compliant.&#10;If you’re thinking about using Mailjet to grow your business, think again. You cannot plan anything medium- or long-term, because your account can be frozen overnight for no reason. This is not a partner; it’s a ticking time bomb.&#10;Our data is top-notch: over 98% deliverability, engagement and click rates far above the industry average, almost no unsubscribes, and nearly zero spam reports. Mailjet doesn’t care.&#10;And if you think support will help? Think again. They take over a week to respond, leaving you completely stranded.&#10;My advice to any small business or startup: run in the opposite direction. Mailjet is unreliable, risky, and completely unsuited for anyone who actually wants to grow their business safely.
