Is there a way to block these? They’re JQuery lightboxes, right?
Most aren't jquery, although many are. I would imagine some low level JS heuristic looking for DIVs that cover the entire viewport (and anything stacked on top of those or within them) could be a nearly universal blocker. Thankfully most set a cookie, so if you just immediately hit reload rather than searching for how to dismiss it, it won't show again.
It's a terrible, terrible idea that is actively user hostile. The problem is THEY WORK. It's disgusting to see how many people blithely fill those in, because then you're stuck with using them because your client/boss loves the conversion rate, despite the fact that it may actually be driving off some of the most potentially valuable visitors. I hate them and do everything in my power to dissuade clients from using them.
Yup, them things sure do work, sadly.
Maybe a browser extension that automatically fills those in with the parent company CEO's email address?
Relative to the comment above about them working:
I want to believe* they don't work.
I want to believe they are just trendy right now, like all the other bullshit trendy things.
*This is why I didn't reply to that comment.

Isn't this just pop-up ads, back from the dead in another form? Instead of showing you a product to make more money, they're asking for your personal info to then ask you later for money (or sell to another marketer for money).
The logical progression will then be pop-under JS boxes, multi-pop boxes that keep spawning whenever you try to close the tab, etc. Maybe this will be in HTML6.
My company creates them for our clients, the conversions are crazy good. It makes me very sad.
Find a new line of work.
Working on it.

If they're coming from Mailchimp (a lot probably are, as it's popular), the following Adblock rule under element hiding should kill:
Yeah that's gonna work great on my iPad.
