Will a Muslim be rewarded for sending messages of adhkar and du'aa' via email, knowing that the reader's intention might not be dhikr or du'aa' but merely reading the message content, while the sender's intention is to gain reward?

"The one who guides to good is like the one who does it," and "The most beloved of people to Allah are those most beneficial to people." Therefore, sending messages that contain invocations (dhikr), supplications (du'a), or religious or worldly information from which people benefit brings abundant good and immense reward, and the love of Allah Almighty for whoever sends them or guides to them. Reading the message before sending it does not prevent the attainment of reward as long as the intention is present at the time of sending.
