Your readers pay for the PDF, not for a file to forward. SendOwl delivers a download – since February 2026 with buyer watermarks on every plan from $39 a month. HelpRange delivers no file at all: each buyer reads a personal, watermarked copy in the browser, and you can take access back.
Your readers pay for the PDF, not for a file to forward.
Protect and sell in one: every buyer reads a personal copy with their e-mail watermarked on each page and downloads blocked. Access ends after the days you set, when you revoke it, or on a refund or cancellation from Kajabi, Whop or Gumroad. From $39 a month per team.
Buyers read in the protected viewer on phone, tablet or computer; download, print and copy are off, so there is no PDF to pass around.
The buyer's e-mail – or your own buyer ID – on every page, like SendOwl's PDF stamping, but on a copy that never leaves the viewer.
Revoke one buyer with a click; refunds and cancellations from Kajabi, Whop or Gumroad revoke access automatically through the webhook.
Choose how many days each buyer keeps access – it ends on its own, also for repeat purchases.
Sell on Gumroad, Kajabi or Whop, on Teachable or Thinkific through Zapier or Make – or use the HelpRange Store with Stripe.
Page-by-page reading analytics per buyer, and an alert when one link is opened from many places.

Each buyer gets an e-mail with a personal link; their e-mail or ID is on every page.
Buyer access is part of Pro ($39 per team per month, unlimited buyers), Unlimited and the 3-day trial – no per-buyer or per-view fees. Plans & pricing
At the entry price they cost the same: SendOwl Launch is $39 a month with a $10,000 yearly sales cap (sendowl.com/pricing, 7 November 2026); HelpRange Pro is $39 a month per team with unlimited buyers. The difference is delivery: SendOwl sends a watermarked file, HelpRange sends no file.
Yes. Since its February 2026 pricing change every SendOwl plan includes PDF stamping ("unique buyer watermarks on every download") and download and time limits. The buyer still receives the PDF file, which can be passed on with the stamp on it.
With a download, no – SendOwl lets you switch off download access for an order, but a copy already downloaded stays with the buyer. With HelpRange the buyer never has the file, so a refund or cancellation from Kajabi, Whop or Gumroad, or one click by you, ends access.
There is no ready-made SendOwl connection. Any platform that can send a webhook, or a Zapier or Make step, with the buyer’s e-mail can grant and revoke access; Gumroad, Kajabi and Whop are documented step by step.
When buyers must keep the file to read offline, when you sell software, audio or other files that are not documents, or when you want one tool for checkout, cart and delivery.
Yes – in the browser on any device, or in the HelpRange viewer app for iPhone, iPad and Android.
