Recommended Email Services with Strapi?

Hi! I was curious if anyone has experience with a good email service (3rd party) to integrate with the Strapi email function. I am new to Strapi and am using it for content creation and am interested in using it to send emails too.

I am aware the out-of-the-box Email function provided in strapi as well as the Sendgrid tutorial online but I was curious if anyone in the community hsa used the email function alone or with another service.

Thanks for any ideas or suggestions and I hope we can all learn.
