What is the ruling on benefiting from an e-commerce website that offers a daily profit ranging between 2.3% and 2.8% of the deposited amount, with the profits continuing to be calculated on the original amount plus the accumulated profits?

What the questioner mentioned is not sufficient to rule on investing in this website. However, if this investment adheres to the legitimate Islamic Mudarabah contract, then there is no harm in it. Legitimate Mudarabah is a contract between two parties where one provides capital and the other invests it, on the condition that the working party receives a pre-agreed, commonly known share of the profit. It is not permissible in it to guarantee the principal capital or to agree on a specific percentage of profit that comes from the principal capital. Caution must be exercised regarding fraudulent and deceptive websites.
