So I don’t think this is a big deal probably, but I just did a build for my blog. It went fine, but I got an email from Netlify with the subject: Your Netlify account and helpful links. The contents of the email start with:
Welcome to Netlify! You just joined hundreds of thousands of developers building faster, safer, and more scalable web projects.
So for some reason, the platform thought I was a new user.
As I said, nothing else seems wrong, so consider this an FYI.
