営業メッセージを有料にしている理由と、お支払いのメリット
Why sales messages are paid — and what you get for 0.50 USD
- 確実に本人が読みます入金確認後すぐ、サイト運営者本人の受信箱へ届きます。迷惑メールとして弾かれることはありません。 Guaranteed delivery to the owner's personal inbox, read by a human. Never filtered as spam.
- 「支払済」として目立ちます件名に [PAID] が付き、一般の営業メールとは別扱いになります。 Flagged [PAID] in the subject line, standing out from bulk outreach.
- 送達の証明が残ります支払いIDとオンチェーンの取引が、届けた証拠になります。 Payment ID and on-chain transaction serve as a public receipt.
- 無料フォーム・未払いの営業は届きません無料フォームやメールで送られた営業・プロモーションは迷惑メールとして扱い、読まずに破棄します。なお、お支払いで保証するのは「読むこと」までで、返信や成約は保証しません。 Sales or promotional messages via the free form or email are treated as spam and discarded unread. Payment guarantees reading, not a reply.
