BY default in opencart can be used in multistore option , that is a great feature that helps admins to use one admin dashboard and operate in 2, 3, or 5 websites and act them as a separate one, and that is all great.

But when you send newsletter from multi stor website no matter what store you sellect all the time emails are sent from the first store main email.

This extension change that making your newsletter emails also separated from each store, now once you select newsletter email to be sent no matter from which store the customer and get email from that store email also will include Store name and REAL STORE EMAIL in a field sent FROM.

This may be a small extension but small extension making a big change:)
