Do you use CMS for a blog page under your main domain name?

Looking to start a blog. Having trouble deciding what to use. I would like whatever we go with to be very easy to use, can be under a our main domain name (ex. domain.com/blog). Also I'm not very technical soo it would be a benefit in technical skills weren't required. Tbh, I'm just looking to boost our SEO ranking and share valuable advice. Right now I'm flirting with Mailchimp, because it also allows me to send e-mails and all of the above but I'm also exploring other options. Thnks you for your answers. Cheers, Luka
