What it is doing
This email uses a single customer testimonial as its core content, presented as a blockquote. The design is very minimal, relying on the compelling text of the review and a single CTA. The preheader text is used to promote a Black Friday sale, which is not otherwise mentioned in the email body.
Worth stealing
The email's entire body is a single, powerful customer testimonial, leveraging social proof to drive sales.
