Authors and publishers selling ebooks directly from their own store want each copy traceable back to the buyer, without turning every sale into a manual file editing job for someone on the team. LemonInk handles that by watermarking a copy of the file with the customer's own data or custom text the moment an order comes through.

LemonInk fits neatly into a Zap alongside Mobile Message, doing the watermarking work in the middle of an automation while Mobile Message handles the text to the customer. When an order is paid in Shopify, LemonInk can watermark that customer's copy with their own data, and the same flow works from a Typeform order form using a custom text watermark instead. Either way, the customer gets a text once their personalised copy is ready, without anyone manually running a file through LemonInk first or checking in on the order to see how far along it is.
