No need for third-party email clients1. The app will communicate with Apple Mail and allow you to request a read receipt for your emails and, at the same time, notify the senders when you read their messages.
Send read receipts in the language of the sender. The language of a message can be detected and used to send read receipts. English, French, German, Italian, Portuguese and Spanish are currently supported.
macOS Sierra Ready
iReceiptMail is fully compatible with OS X Mountain Lion, Mavericks, Yosemite, El Capitan and supports Apple Mail versions 6 to 10. The user interface is now available in English, Italian and Spanish.
