For founders, finance teams, and operators selling a business
Export Gmail records for M&A due diligence
Most small-business sales generate a diligence checklist that's almost a parody of itself: every signed customer contract, every vendor agreement, every dispute resolution, every key-person correspondence trail, plus enough financial backup that the buyer's accountants can recreate four years of P&Ls. For owner-operated businesses, a huge slice of that evidence lives in the founder's Gmail — because the founder has been the head of sales, the lead vendor contact, and the de-facto legal department for the entire life of the company.
ThreadPDF is the tool for pulling that email evidence into the data room. It's a Chrome extension that exports the Gmail threads you select to PDF, attachments included, all processed locally so nothing gets uploaded to an outside server in the middle of a confidential sale process. The output is a folder structure you (or your broker) can drop straight into the buyer's VDR — same shape every diligence team expects.
How to build an M&A email archive with ThreadPDF
- 1
Install ThreadPDF on the founder's Chrome
Standard Chrome Web Store install on whoever's account contains the deepest history — usually the founder or the long-tenured ops lead. Multiple people can each run their own exports from their own inboxes.
- 2
Map the diligence checklist to Gmail searches
Customer contracts → label:Contracts from:@customer-domain.com. Vendor agreements → label:Vendor from:@vendor-domain.com. Disputes → label:Legal or label:Dispute. Key-person relationships → from:@major-customer.com over the entire date range. Each diligence section gets its own search.
- 3
Bound by relevant date range
Most diligence requests cover the past 3-5 years ("trailing twelve months," "since founding," or a specific lookback period the buyer's LOI specifies). Add after:2021/01/01 to each search to keep the export focused.
- 4
Export each search as PDFs with attachments
Pick PDF, enable attachments. Each Gmail thread renders to one PDF (preserving the sender / recipient / date headers and full message body); attachments ship in a per-category ZIP. Run separate exports per diligence section so the VDR structure stays clean.
- 5
Hand off to the broker / advisor for VDR upload
Your sell-side advisor or banker will already have a VDR structure (Datasite, DealRoom, ShareFile, sometimes just Drive). The folder of PDFs maps 1:1 to their diligence index — drop it in, redact anything sensitive (often handled by counsel), and the email evidence layer is done.
What this looks like in practice
A founder prepping a small SaaS company for sale might produce this structure ahead of opening the data room.
Per-diligence-section exports, organized for the VDR:

EXPORT_LOG.txt
Date of each export, person who ran it, Gmail query used,
thread counts. Counsel uses this to confirm completeness.- Privileged threads (anything with outside counsel) typically get pulled into a separate folder and handled by your counsel for privilege review before they go in the VDR.
- If the buyer's diligence team asks follow-up questions, the same Gmail queries are easy to re-run — the workflow is reproducible.
Why ThreadPDF for diligence specifically
On-device matters during a confidential sale process
M&A processes are sensitive long before they're announced. Routing your founder's email through a third-party server-side conversion tool adds a vendor to the chain — one that could leak the existence of the deal. ThreadPDF keeps everything in the browser, so the sale process stays where it should: between you, your advisor, and the buyer.
Folder-per-section structure maps to standard VDR indices
Every M&A diligence index has a similar shape (commercial, legal, employment, financial, IP, IT). Running separate Gmail exports per section produces a folder structure that drops straight into Datasite, DealRoom, or whatever VDR the buyer uses — no reorganization.
Email plus attachments — the full context the buyer asks for
Diligence teams don't just want the signed contract — they want the negotiation that led to it, the amendments after, and the email trail that proves performance. ThreadPDF pulls both halves: the full thread (negotiation, amendments, performance discussion) plus the original signed attachments.
Get the email evidence into the data room
Install ThreadPDF on the inboxes that hold your history, run the diligence searches, and hand a folder to your advisor. Pro is $4.99/month — a rounding error in a deal cost stack.
