Question about Email with My Own Domain Name

A confession: I neglected sending out my newsletters the last two months. The last time, I had to migrate my account to a new and improved Mailerlite.

This time I had to login three–or was it four?–times before I could start working on my newsletter. Once I got in, I found Mailerlite had a notice posted. Starting February 2024, newsletter campaigns cannot be sent from a free email account. I must own my domain.

So, what email provider do y'all use? Should I go with Google Workspace for $12 per month with a one year commitment? Or are there gooder options?
