I have a new client who I'm doing lead magnet packages for. Each project includes the lead magnet content, a landing page, and an email drip.

He's a fantastic client, great guy to work with, but he has one request I'm unsure how to handle. He wants me to provide design direction and prefers that it's visual - screenshots of examples and mockups.

I've written text descriptions for design direction before, but I'm ultimately not a designer. I'd like to accommodate this client since he's very much worth my time.

Is there a user-friendly tool I can use to make ebook page, landing page, and email mockups without having design skills?

I'm open to any advice on how to handle this, thank you!
