I found using newsletter platforms like ConstantContact and Mailchimp very easy to use. I created different email banners every week as well use the same ones I created for previous newsletters.
My manager cared greatly about giving his viewers a consistent user-friendly experience and I worked every week to promote deals and showcase our products. Some designs were each consistent to the product brand and some represented basic weekly deals similar to deals people find in a Sunday ad.
I showcased other various designs in email newsletters like for the Hurricane live event that was held at the store. Click images below for full view.
Just like the weekly deals I even created designs for holiday deals.
