Creating a Small Newsletter for Friends

Hi fellow Indie hackers.

As part of my journey, I want to share things with friends and people who like my path and want to know more about my journey.

I want to know if you can help me in choosing some sort of email provider where I can send one off emails to about 50 people or so on a weekly basis.

I thought of sendgrid as it was allowing individual emails to be sent before but I think they no longer allow that.

Any help is appreciated.
