Gmail 用の無料・無制限のメールトラッカー。数百万のユーザーに信頼され、正確で信頼性が高く、GDPR 準拠、Google による監査済み。
Mailtrack® が他のメールトラッカーと異なる点
➤ 最も正確で信頼性の高いメールトラッカー
Mailtrack は誤った自己開封(自分で自分のメールを開いた記録)を排除し、グループメール内でも各受信者の開封を正確に追跡することで、誰があなたのメッセージに関心を持っているかを明確に把握できます。
➤ 迷惑メールフォルダへの送信を回避
Mailtrack は Gmail の信頼できるインフラを利用して、ユーザーの個人 Gmail アカウントから直接メールを送信します。外部サーバーを使用せず、迷惑メールとマークされるリスクを最小限に抑えます。
➤ グループメール内の受信者を個別に追跡
従来のメールトラッカーは、メールが開封されたかどうかは表示しますが、「誰が開封したか」は分かりません。Mailtrack は受信者ごとに開封状況を個別に追跡できるため、各メール受信者の反応に基づいてより効果的なフォローアップが可能です。
➤ リアルタイムでフォローアップ通知を自動受信
メールが複数回開かれた場合の オープンスパイク通知 や、古いメールが再び開封されたときの リバイバル通知 を受け取り、強い関心を示す相手を把握し、最適なタイミングで再度コンタクトが可能です。さらに、メールが 24〜48 時間以内に返答されなかった場合には 未返信通知 も届きます。
➤ プライバシー重視。個人データには一切アクセスせず、販売もしません。
Mailtrack はユーザーのメールを保存しません。メール、閲覧履歴、個人データを販売・貸出・共有することも一切ありません。情報は完全に保護されており、GDPR(EU 一般データ保護規則) に完全準拠しています。
➤ 暗号化による安全性と合法性の確保
Mailtrack は毎年 Google による監査を受けており、ISO(情報セキュリティ管理)認証を取得し、Google Cloud パートナーとしても認定されています。システムには、業界最高水準の 256 ビット AES 暗号化 を採用しています。
Mailtrack が Gmail 向け最高のメールトラッカーである理由
✔️ グループメール内の個別トラッキング:複数人に送ったメールの誰が開封したかを把握
✔️ 完全なメール開封履歴:いつ、何回メールが開かれたかを正確に確認
✔️ リアルタイムでのメール開封追跡と通知
✔️ フォローアップ通知:24〜72 時間以内に開封または返信がない場合に通知
✔️ リンククリックの追跡
✔️ 誤検出の回避:自分宛のメールは追跡されません
✔️ Gmail に完全統合:Gmail 内でそのまま使用でき、普段のメール習慣を変える必要なし
Mailtrack のリアルタイムメールトラッカーで、相手がメールを開いた瞬間に把握し、最適なタイミングでフォローアップしましょう!

- The enshittification of this extension has started. First you forced free users to manually remove the branding signature every single time. Now you have removed the free limit that allowed viewing tracking history for 10 emails per month. Step by step, useful features for free users are being stripped away just to push paid upgrades. That is not improving the product. That is squeezing the user base. Uninstalling it and switching to an alternative. If others feel the same way, leave a review and switch so the developers realize they do not have a monopoly.

- OzMusic Festivals
- Very useful for tracking whether someone has opened an email or not (free version). Not foolproof, because I think recipients can choose to not acknowledge receipt if they want to. I'd give it more stars, but I've just removed the extension from Chrome and then reinstalled after I found that gmail was forever trying to load unsuccessfully, and it (gmail) would constantly throw up pop ups saying it needed to refresh. I suspected this app so I removed the extension and then reinstalled. The problem has now gone away. Might be a coincidence of course ???

- I have been using this Mailsuite for so many years but their only problem is that it always affects gmail e.g link blocking of mail and make email enter spam when message
- Ned Totah
- I have been using Mailsuite in my business for 2-3 years which was a paid subscription and it's worked great during this time. In early December 2025, for unknown reasons Mailsuite stopped working and is no longer tracking emails. Between early December till now at the end of January 2026, I have sent 7 emails during this time to Mailsuite support and have had NO response to any of my support requests. I also set up Mailsuite using an admin email address for my company which the tracking was working and I sent 2 additional support requests and still received NO response from support. I do know from the admin email account that support did in fact open my email after it was sent since the tracking was working on this other email address. There is no way to call the company and the only way to contact support is through email, though they do NOT respond. I have since cancelled my subscription for this service and will seek other options..

- MailSuite transformed my cold email game. Real-time tracking shows exactly when prospects open my eShopbox Plus pitches, letting me follow up at peak engagement moments. The mail merge saved hours creating personalized SOR model emails for D2C brands. What I love most: ✅ Gmail integration - zero learning curve ✅ Click tracking - know which links get attention ✅ Mobile app - track opens on the go ✅ Free version delivers 80% of pro features As an SDR hitting 50+ daily outreaches, MailSuite gives me X-ray vision into email performance. Response rates up 25% since switching. Essential for anyone in sales development! Highly recommend for sales teams 🚀
