概要

今ではレガシーな技術として認識されているメールですが、レガシーな技術であるがゆえに、歴史的な経緯から多くの積み重ねと独自の複雑性があります。

メールは様々なシーンで活用されていますが、利便性が高いことから悪用されるケースもあり、予想外のトラブルや意外な落とし穴に遭遇することも多いです。

そこで今回は、メール送信に携わったことのある皆様の実装上のナレッジや運用で得たノウハウ、さらにはメール送信にまつわる成功体験や失敗談。最近のメール環境の変化や、新しい公式ツール(Postmaster Tools v2 など)の使い方まで、あなたの体験談やノウハウを募集します。

ECの顧客・注文管理、予約システム、SaaSツール、災害警報など自社サービス上でメール配信機能を実装した話や、大量のメールを送信するメールサーバーの運用話まで、メールにまつわる様々な経験や学びを投稿してください!

(例)

  • SPF/DKIM/DMARCの設定がうまくいかずに悩んだ経験、その解決方法
  • Gmail メール送信者のガイドライン変更にあたり、実際に対応したこと
  • 迷惑メール判定されないためにやるべきこと
  • 自社サービスにメルマガ機能をつけてみた実体験
  • SMTPサーバーのパスワードがクラックされて自社環境から大量のフィッシングメールが送られてしまった話

など、その他にもblastengineを実際に使ってみた体験談なども大歓迎です!

こんな人におすすめ

  • メールサーバーの構築や管理に携わったことがある方
  • SPF/DKIM/DMARCの認証技術を実装・運用した経験がある方
  • Webサービスで申込完了メールや自動返信メールの送信システムを構築したことがある方
