Dear Mr. Williams,
Thank you very much for taking the time to meet with us today. We truly appreciate the opportunity to discuss the partnership, and I found your insights into the European market particularly valuable.

APOLOGY — Delivery delay
Subject: Apologies for the Delay — Order #5678
Dear Ms. Johnson,
I'm writing to apologize for the delay in delivering Order #5678. I understand this has caused inconvenience, and I take full responsibility.
The cause was a shipment issue at our warehouse, which we are now actively addressing. The order will arrive at your office by Tuesday, May 12 at the latest.
As a gesture of our apology, we'd like to offer a 10% discount on your next order. Please don't hesitate to reach out with any concerns.
Thank you for sharing the partnership proposal and for taking the time to walk us through the details last week. We truly appreciate your thoughtful presentation.
After careful consideration, I'm afraid we won't be able to move forward with this opportunity at this time. The current direction of our business doesn't align as closely with the proposal as we'd hoped.
That said, we very much value the relationship and would love to stay in touch for future opportunities.
Wishing you all the best with this initiative.
件名は具体的に → "Question" だけより "Quick Question About the Q3 Report" のように何の話か明確に
5W1Hを意識 → Who / What / When / Where / Why / How を本文に含めると伝わりやすい
パラグラフを分ける → 1段落 = 1トピック。読み手の負担を減らす
"Best regards" は万能 → 迷ったら必ずこれでOK
24時間以内に返信 → 即レスできなくても "I'll get back to you by [date]." と一報を
署名を整える → 名前 / 役職 / 会社名 / 連絡先 を明記
送信前にチェック → ✓宛先 ✓件名 ✓敬称 ✓添付 ✓誤字 を確認
ビジネス英語メールで大切なのは 「正しさ」より「明確さと礼儀」。完璧な英語より、「具体的・丁寧・読みやすい」 3点を意識すれば、十分プロフェッショナルなメールになります。"Could you ...?" / "I'd like to ..." / "Best regards," の3パターンを軸に、シーンに応じてフォーマリティを調整するだけで、ほとんどのビジネスシーンで困りません。
