Maintenance alerts through email (feature request)

Hello,
And,I have received an alert from Wordpress saying that my PHP version was outdated. I then visit https://wordpress.org/support/update-php/ that says that updating PHP version will X3 or X4 my website speed.
I had contacted support about my website slowing down.
I have lost my SEO ranking on all my keywords and I wouldn’t be surprised this was one of the factors.

I think it’s essential you keep me up to date when something needs to be improved on my server. Maybe you did. But I would need a consistent email subject line to know, I need to pay attention to the emails you send me for maintenance necessary actions

Thank you
