Email Assistant
What you can send and what Deck can read
Attachments on a forwarded email are uploaded to the right project automatically — the same way you'd upload them by hand inside Deck.
What Deck can read
- PDFs — contracts, reports, decks, signed agreements
- Word documents (
.docx) - Excel sheets (
.xlsx) - PowerPoint (
.pptx) - Plain text and Markdown
- ZIP archives — unpacked automatically; each readable file inside is filed against the project
If you forward a file Deck can't read, it's still attached to the project — Deck just won't be able to reason over its contents.

What happens after the upload
Big files take a moment to process. Deck replies when everything's ready:
- "3 documents added to Acme Corp." — done, you're good.
- "2 of 3 documents added; one couldn't be read — try uploading directly." — partial success. Uploading directly means dropping the file into the project inside Deck — see Open your projects.
Limits
Email and direct upload have different size caps. If a file is too big to forward, upload it from inside Deck instead.
| Path | Per-file size | Notes |
|---|---|---|
| Email forward | ~25 MB per message | Capped by your email provider. ZIP archives are unpacked — the readable files inside count toward this per-message cap. |
| Direct upload in Deck | ~100 MB per file | Drop files into the project from Projects. Best for large reports, full document sets, and big spreadsheets. |
