I am looking to change the main email on my account. However I have 40+ client websites where Cloudflare’s caching is linked into the website’s caching plugin via this email and my API key (mostly W3 Total Cache, and Hummingbird Pro on WordPress).
Will updating my email break this link on these websites? I.E. will I have to update all 40+ websites with my new email? Or will the API key be sufficient to keep the link?
