I switched from WordPress to wix, in the process I cancelled my email which was based at my host. I didn't realize that my subscription at MaileLite was the email I signed up with. I reached out to MaileLite as I was locked out of my account. The next day Denise from support was already on my case and and changed my email, and I was able to sign in my accout again. Kudos to Denise for a swift response.
