I want to simplify my "Frankenstein" tech stack for my business. Any tips?

I've been running my operations for a couple of years now and I'm reaching a breaking point with my tech setup. I have my website on one platform, email marketing on another, and my courses hosted on a third. It feels like I'm constantly troubleshooting integrations and paying for Zap⁤ier just to keep the lights on instead of actually growing the brand. I'm looking at moving everything to one platform because the all-in-one approach seems much cleaner but I need to know if it can actually handle the complex automations and volume that a more established business needs.

Has anyone made the switch to a platform like this to simplify their operations without losing the professional-grade features? I really want to spend more time on strategy and less time being a part-time IT tec⁤h for my own company.
