I can make any HTML email be compatible with Mailchimp's easy to use drag-and-drop editor. You will be able to repeat, hide or delete elements template and edit text and images as well without learning code. Hence, this template can be re-usable on your end.
This also includes installation to your Mailchimp account.
This task doesnt cover customization or any other modification to the template design.. nor make it mobile responsive. Only the added code so you can use the HTML email for Mailchimp.
NOTE: If you need a mobile responsive email template, you can refer to my other service posted here :)
