Hi, I can do it in 1 day. Please share credentials with proper details so I can start the work right away in order to create the unsubscribe functionality.
I am having a team of expert developers that are providing ecommerce solutions to all our clients from the last 6 years. Beside web designing, I've got expertise with PHP, Java, jQuery, HTML. And this includes custom development as well.
Let's discuss the project in detail over chat.
Waiting for you with a positive response.
