A Writer by Any Other Name?

Although fantasy and science fiction are my favorite genres, I also like to read mysteries, especially cozy mysteries. It's probably not surprising that I've come up with an idea for a cozy mystery series. I'm trying to do more worldbuilding and plotting with this project, but even before I write the first word, I also have to consider the marketing aspect. Should I publish these stories under my own name or a pen name? Traditional thinking has always been that you need different pen names for different genres so readers can distinguish them. However, this doesn't seem to be too much of a concern for indie writers. Honestly, I have enough trouble doing social media and marketing for one name; doubling it would make it even harder. Book covers and blurbs do a better job of signaling genre than names, and I would put different books on different pages of my website.

Do you use a pen name, or have you thought about it? Let me know in the comments.
