Send a PDF Letter
What it is
PDF letter mode lets you upload any PDF document as a windowed or windowless 8.5×11 letter. thanks.io prints it, addresses it, envelopes it, and mails it. You never touch the envelope.
This is the right tool for: newsletters, CMA reports, insurance policy summaries, multi-page proposals, and any document that lives naturally as a full-page formatted file.
When to use it
- Monthly newsletter to your book of business
- Automated CMA (Comparative Market Analysis) letter to a prospect
- Insurance policy renewal notice or summary
- Multi-page proposal or offer package
- Any content that already exists as a PDF and needs to be mailed
Cost
The first physical page is included in the base per-piece price. Each additional physical page adds approximately $0.20 per piece. A physical page is one sheet of paper — a page printed front/back counts as one physical page, not two. For current pricing, see thanks.io/pricing.
Tips & best practices
- Add your phone number, email, and website to every page of the PDF - not just the first page. Recipients sometimes flip to the last page first.
- For newsletters, include one clear call-to-action on page 1. "Scan here to schedule a call" or include your direct phone number with a QR code.
- Use personalized salutations in the PDF if your tool supports it (e.g., Canva doesn't support variable fields; use ChatGPT to pre-generate personalized copies, or use thanks.io's message template field alongside the PDF).
- Test with a single piece to yourself before sending a full list.
Limits & gotchas
- PDF-only mode is available for both windowed and windowless letters. For windowed letters in PDF-only mode, ensure the address block on page 1 of your PDF falls within the window zone.
- Each additional physical page costs $0.20 per piece. A sheet printed front/back is one physical page, not two. A 4-page PDF (2 sheets, front/back) = base price + $0.20 × 1 additional physical page.
- Duplicate Prevention applies (36-hour window), same as all other mailer types.
