現代のコミュニケーションにおいて、電子メールは非常に重要な役割を果たしています。2023年には世界中で毎日3,473億通のメールが送受信されました。それぞれのメールを意図した宛先に届けるため、DNSではMail Exchanger（MX）レコードによってメール転送先のメールサーバーを指定しています。
メールサーバーはユーザーが独自に作成することもできますが、ほとんどの人は、複雑なサーバー運用を避けてメールサービスプロバイダー（ESP）のサービスを利用しています。ESPのサービスでは通常、ストレージ、セキュリティ機能、使いやすいインターフェースを全て提供しており、ユーザーにメンテナンスの負担をかけません。
