Newsletter popups convert at 1%. 99% of your readers ignore them.
Popups interrupt before readers see your content. They collect emails from people who are not engaged. Those emails do not convert. There is a better way.

Three steps to a bigger, better email list
Reader finds your content
Through search, social, or a direct link. They see your article and start reading.
Registration wall appears
After a free preview, readers enter their email to keep reading. No popup. No interruption. A natural exchange of value.
You own the relationship
Every registered reader goes straight to your email list. Nurture them with newsletters. 5–10% convert to paid subscribers when you flip the switch.
Everything you need to grow your list and your paid subscriptions
Install in one click from the WordPress plugin repo. Works with any theme, any host, any caching setup. Everything below works out of the box.
Registration wall
Replace popups with a content-driven registration wall. Readers give their email to keep reading, a fair exchange that builds higher-quality lists.
Stripe Connect built in
Turn on paid subscriptions in one click. Stripe is already wired up, no upgrade or migration required. Just a 10% revenue share on new paid subscribers.
AI scraper protection
Block AI bots from crawling your content for free. Protect your intellectual property while growing your email list at the same time.
Metered content
Control how many free articles readers see before the registration wall. Fine-tune your meter to balance discovery with list growth.
Export to your email service
Export new registered subscribers and import them into Mailchimp, Kit, ActiveCampaign, or any email platform. Upgrade to a paid plan for automatic ESP syncing.
Customizable messaging
Control the registration wall copy, design, and placement. Match your brand. Speak in your voice. No generic popup templates.
Popups collect emails. Registration walls build relationships.
When a reader registers to access your content, they are making a commitment. They want what you have written. That intent means higher open rates, more engagement, and more paid subscribers down the road.
