Everything you need to grow and earn with recommendations

Paid picks for growth, free picks for partnerships, and a quality check that makes sure every subscriber is real.

Paid picks

Grow with subscribers who stick. Pay only after the quality check.

Other newsletters recommend yours to their brand-new subscribers. You set the price per subscriber and you're only charged once each one passes the quality check.
  • Pay as you go: set your own price per subscriber and top up from $25
  • Cap your total budget and pause any time
  • Approve every partner and see their quality score first
  • Rejected subscribers are refunded to your balance automatically

Quality & anti-fraud

Fraud protection you never have to think about

Every reader Subswell sends is checked before you pay a cent. Fake and low-quality signups are filtered out automatically, so your budget only goes to real people who chose to subscribe and stay engaged.

Always on, always improving, and built for campaigns of any size. If a reader doesn't make the cut, the charge goes straight back to your balance. No disputes, no chasing.

Standard check

Strict by default

Every reader is screened from the moment they sign up until you pay. Only real, verified people who are still on your list at the end make it through. No bots, no fakes, no throwaway signups.

★ Premium check

For readers who actually read

Everything in Standard, plus proof of real interest: you only pay for readers who actively engage with your newsletter. Our highest-quality subscribers.

  • Only real readers

    Your budget goes to real people who chose to subscribe. Nothing else counts.

  • Automatic refunds

    Anyone who doesn't pass is refunded to your balance. No disputes to file.

  • Readers who stick

    Built to bring you readers who open, read and stay, not names that go quiet the day after they join.

  • Never charged twice

    One paid subscriber per reader per newsletter, ever.

  • Every newsletter reviewed

    Publishers are vetted by our team before they can earn.

  • Protection at any scale

    The same standard on your first referral and your ten-thousandth.

The widget

Built for the moment a reader says yes.

Our recommendation widget appears right after someone subscribes, when they're most open to discovering more great reading.
  • Isolated styling, so it never clashes with (or breaks) your site
  • Lightweight, dependency-free script that loads asynchronously
  • Customise the headline, the number of recommendations and paid or free mix
  • Live preview in your dashboard before anything goes live
Integrations

Works with the email platform you already use

Connect in a couple of minutes. New subscribers go straight onto your list, and the same connection lets us confirm they're real before you pay. Your API keys are stored encrypted.
