Short answer: yes — but done well, not done annoyingly.
Opt-in popups have a bad reputation, and it’s earned. We’ve all hit a site and been smothered by a popup before we’ve read a word. But the data is stubborn: a well-timed opt-in form converts far better than a quiet box in the sidebar that nobody notices. The trick is timing and targeting, not volume.
The right way to use popups
Don’t ambush people the second they arrive. The smartest approach is exit-intent — the popup only appears when someone is about to leave anyway. They’ve read your content, they’re heading for the door, and you offer them something useful on the way out. Nothing lost, plenty to gain.
Add a bit of targeting — show a different offer on different pages, don’t show it again to people who’ve already subscribed — and a popup stops being a nuisance and starts being your best list-building tool.
The tool I’d use: OptinMonster
For this I’d point you to OptinMonster. It’s the most capable lead-generation tool of its kind: popups, floating bars, slide-ins and inline forms, with the exit-intent and targeting that make the difference between irritating and effective.
It works on any site — WordPress or otherwise — and plans start around $9 a month, with a free trial that doesn’t ask for a card. You can build your first exit-intent campaign in an afternoon.
Don’t forget where the emails go
A popup is only as good as what happens next. Connect OptinMonster to Kit so every new subscriber lands in your email list and gets your welcome sequence automatically. Capture the email, then actually use it — that’s the whole game.
