Since launching I've been building a mailing list. I have over 4k subscribers but have never sent an email. After the V2 launch I decided now was a good time to send one out.
After advice from a friend I decided to switch to a more personal/indie approach and not pretend to be a large faceless company.
I used sendinblue.com as it was much cheaper than MailChimp. the reception was positive and I had a small spike in donations.
