A client who runs a software company wanted me to design an e-mail newsletter. He didn't give me much direction, just that his goal was to get people to sign-up to receive for a promotional giveaway. I was already seeing red flags, but I decided to go ahead with the work anyway.
I designed a newsletter that matched the colors and fonts of his logo and website, with tech-savvy phrases, modern colors, and fonts.
Client: Here, let me work on it.
A day later, I looked at how he re-designed the newsletter. It had neon BOGO!! and BUY NOW!! phrases all over it, in bright green and red colors and large bold Times New Roman Font.
I didn't follow up with him after that.
