Overwhelmed with MailChimp

I does a lot. That's what happens when you are an older company. Right now I have it just setting up a mailing list for a product that I am developing, but it just seems like too much for me.

I am able to get it all up and running, but I don't like the fact that the emails come from my personal account and I feel like I have to google every time I want to do something that seems straight forward.

I have built a Carrd site and was able to get MailChimp integrated, but I want to find something a bit more straight forward that doesn't to everything. Carrd has a list of email providers it plays nice with (MailChimp, Revue, ConvertKit, MailerLite, GetResponse, EmailOctopus, Sendinblue, SendFox, and Sendy). I'm interested if others feel the same way and what they use instead.
