Most email tools stop at opens and clicks. AuthorSend goes one step further and connects your sends to actual sales, so you can see which email drove which revenue.
KDP sales attribution
If you sell on Amazon, connect your KDP account. AuthorSend compares your baseline daily sales against the window right after each send and attributes the lift — units, Kindle Unlimited page reads, and estimated royalties — to the campaign that caused it.
Smart links for any store
Don't sell on Amazon, or sell somewhere else too? Use smart links in your emails. They track clicks through to your store or page and attribute conversions back to the campaign, so you get ROI even without a KDP connection.
Why it matters
Once you can see revenue per send, you stop guessing. You learn which kinds of emails — a personal note, a discount, a new-release announcement — actually sell books for your readers, and you do more of what works.
