The only email platform that tracks to the royalty check
Every other platform stops at clicks and leaves you guessing whether a campaign sold books. AuthorSend connects to your Amazon KDP account, compares baseline sales to the campaign window, and shows the units, KU page reads, and estimated ROI each send actually drove.

See the sales spike, not just the open rate
Connect Amazon KDP through the official Amazon API — credentials encrypted, connection status and sync errors always visible. AuthorSend syncs your daily sales and Kindle Unlimited page reads, learns your baseline, and attributes the lift in the campaign window to the email that caused it.
- Daily sync of units, price, royalties, and KENP page reads — broken down per ASIN and per title
- Attributed units, attributed KU pages, and estimated ROI for every campaign, with sales-spike detection
- Honest statuses: when a result isn’t statistically meaningful, we say “insufficient data” instead of inventing a number

One link per book, every store covered
Stop pasting four retailer URLs into every email. Each book gets one universal smart link that routes readers to Amazon, Apple Books, Kobo, or Barnes & Noble — with a default-store fallback and device-type routing so everyone lands somewhere they can buy.
- Per-store click split, total click counts, and device breakdown for every link
- Amazon attribution tags so even pre-order clicks are credited to your campaigns
- Reader-level linking: when a click comes from a tracked email, you know exactly which subscriber it was

Everything between the send button and the sale
KU page reads
Kindle Unlimited KENP reads sync daily alongside sales, so page-read royalties count too.
Per-ASIN breakdowns
Sales split per ASIN and per title — see which book in the series the campaign moved.
Sales-spike detection
Baseline daily sales vs. campaign-window sales surfaces the spikes your emails create.
Honest attribution
When a result isn’t statistically meaningful, the status says “insufficient data” — never a made-up ROI.
Pre-order attribution tags
Amazon attribution tags on smart links credit pre-order clicks back to the campaign that drove them.
Reader-level click linking
Clicks from tracked emails tie back to the individual subscriber, not an anonymous count.
For years I knew my open rates and nothing else. Now I send a launch email and watch the attributed units land next to the estimated ROI. It’s the first time my newsletter has felt like a business.
