Real handwritten letters, rendered at production scale. Plugged into your existing fulfilment stack via REST API and webhooks. Output delivered straight to your SFTP or S3 as PDF/X-4 with your ICC profiles embedded — the print-house-ready format your Xerox iGen actually wants.
Priced in pence per page — wholesale rates for platform partners. You quote your customer at your own retail rate and keep the margin. White-labelled, always.
Your CRM, campaign tool, or ops workflow — however you already assemble a mail-out. Trigger via REST or upload a CSV.
Renders each letter with real pen physics + your chosen ink + your layout template. Fires proof-then-approve or straight to full render.
Output arrives PDF/X-4 with your ICC profile at your SFTP or S3 — straight into the print floor's hot folder. No portal detour.
Everything a production mail workflow actually needs — not just a nice-looking preview.
Built for the teams that actually ship direct mail.
Rendering across multiple clients from one account. Sub-clients get their own usage rollup + delivery target. Proofing is built in.
Offer handwritten campaigns as a service without building the pipeline. White-label — the output is your PDF on your storage; Inkli branding never appears on the artwork.
Add handwriting-as-a-service to your catalogue. PDF/X-4 with your ICC lands in a hot folder. No new floor equipment.
Wholesale rates. Retail margin yours.
Platform pricing is per page in pence — not a subscription tier. Mail houses, agencies, and print shops resell handwritten campaigns at their own retail rate; the margin between wholesale and retail sits with you.
White-labelled end-to-end. Your brand on the invoice; your delivery target on the output; your customer never sees Inkli. The rendering engine is ours — the customer relationship is entirely yours.
