Let Gmail forward every SaaS receipt for you.
Add one forwarding rule in Gmail or Google Workspace. From then on every receipt lands in SubDupes by itself, and your subscription inventory builds without manual data entry — and without SubDupes ever reading your mailbox.
Create a filter
The safest integration is the one that never logs in.
SubDupes never connects to your mailbox, holds an OAuth token, or asks for read access. A forwarding rule you own sends us the receipts, and only the receipts.
Receipts Only
Only the messages your forwarding rule matches ever reach us. Nothing else in your mailbox is sent, because nothing else is forwarded.
No Training Data
Forwarded receipts are never used to train AI models. They are parsed for billing details and nothing else.
Metadata Storage
We store the extracted subscription data — cost, date, vendor — not the message bodies it came from.
Turn It Off Anytime
The rule lives in your Gmail settings, not ours. Delete it and the forwarding stops immediately — there is no connection for us to hold.
How the Data Flows

Raw connection
Receipt Detection
Financial filters applied
Metadata Extraction
Cost, dates, seats parsed
SubDupes Dashboard
Clean, actionable data
Zero data entry required.
Google Workspace integration is the fastest way to achieve 100% visibility. It completely eliminates the need to chase down department heads for their software lists.
Backfill Your Last 12 Months
Search your mail for past receipts and forward them in one batch. They are parsed exactly like new ones, so your first day already reflects a year of spend.
Real-Time Syncing
No manual CSV uploads. Once the rule is in place, every new receipt is forwarded the moment it arrives and the dashboard updates on its own.
Automatic Categorization
Our engine recognises the vendors in our catalogue. A receipt from 'Atlassian' is automatically categorised as 'Project Management', making overlap detection instant.
One rule. 60 seconds.
Stop relying on manual spreadsheets. Add a single forwarding rule in Gmail and your software spend starts assembling itself — no account connection, no inbox access.
