I like that it's free to use, easy for beginners who don't have much experience with coding or marketing in general! It makes creating content super simple compared to other platforms where you need an entire team of people just to create one post/page (which is what we do!).
The support staff are also very helpful when there’s any issue at all - they're always quick enough to get back within 24 hours usually :) We started using mantra about two years ago now but didn't really know how powerful this tool was until recently as our business has grown exponentially since then!!
