Hey!
I would focus on the email list first. I might start with a return email:
“Hey I’m back!” Share some things that have been going on, but you want to rekindle the fire and connect again.
Then, I would set an expectation of how often you will email. At least once a month, but I would start at once a week.
You will probably lose more people in the first month than gain, but thats okay, it happens. Then work on building the email list back up.
That’s where I would start. I would probably do the same thing with your website too. Nothing to wild, just rebuild some connection and restart consistency.
I hope this helps.
