For authors / Advance review copies

Still chasing
readers for
review links?

Send advance review copies without managing every follow-up yourself. Choose your readers, personalise their files and schedule reminders that stop when they report back.

Personalised copies

Found your book
on a sharing site?

Each reader gets an EPUB or PDF marked with their name and a unique copy reference. Found a file online? Upload it or enter its reference to match it to the reader it was prepared for.

A match identifies the copy, not who shared it. You can block that reader from future campaigns.

Where the copy reference lives

The unique reference, called a Copy ID, appears on a visible notice page or footer and in the file metadata. Hamsterra reads that ID; it does not identify files by analysing their content.

Reader applications

Tired of throwaway
email sign-ups?

Keep disposable email domains out of your applications, with bot checks on application and sign-up forms. Then review the applications and decide for yourself who gets a copy.

Bot checksEmail screeningYour approval
A little more about the checks

Cloudflare Turnstile protects the forms. The list of disposable email domains is refreshed daily. These checks do not verify a reader’s identity.

Reminders & reviews

Still sending
“just a reminder”?

Set your campaign reminders and let Hamsterra handle the follow-up. Choose reminders before the review deadline, before release day or monthly. Only readers who haven’t reported back receive them.

When a reader adds a review link or marks “did not finish”, their reminders stop. Review links are self-reported, not verified on Amazon or Goodreads.

What about review links?

See book-page visits, requests for advance copies, first downloads and submitted review links as separate steps. Find where activity drops off without mistaking a download for a finished read.

Copy requests are applications for advance review copies (ARCs). A download doesn’t tell you whether the book was read.
