Unsubscribes after sending an email

Hi! I have an opt-in on my website and an email provider that sends an automatic email after someone subscribes. The other day I mastered up the courage to send a recent blog post I had written to my list and immediately got two unsubscribes. The result of my unintentional model is to avoid sending more emails to my list out of fear of rejection. What is an intentional thought I could choose in order to continue serving the subscribers to my list? Also, I like to indulge in overwhelm and perfection when it comes to taking care of my people. Is it a good idea to write a weekly blog post which I then send to my list, or would it be better to provide them with something they can only get by being on my list? Thanks in advance.
