Attachment Hippo is a Gmail™ add-on that automatically saves email attachments to Google Drive™. It monitors your inbox and saves attachments to the folder you choose, based on rules you set by sender, subject line, keyword, or Gmail™ label — without any manual steps.
Once configured, it runs in the background every day. There is nothing to trigger manually and no need to open individual emails to save their attachments.

## How it works
You create rules that tell Attachment Hippo which emails to watch and where to save their attachments. For example, you can save all PDF attachments from your accountant to a folder in Google Drive™, or automatically file every receipt from an online store to your expenses folder. Files are always saved in their original format.
You can also set a start date in the past to save attachments already in your inbox — useful if you want to catch up on existing documents without going through emails one by one.

## What it is used for

- Saving PDF attachments from Gmail to Google Drive™ — PDFs are the most common type of email attachment. Attachment Hippo detects PDF attachments as emails arrive and saves them to Google Drive™ automatically. This is useful for anyone who regularly receives invoices, statements, or documents by email and wants them stored in one place without opening every email manually.

- Keeping personal finances organised — Individuals who receive bank statements, utility bills, insurance documents, or online order confirmations by email can use Attachment Hippo to save those attachments to Google Drive™ automatically. Instead of downloading files one at a time, everything goes to the right folder as it arrives — ready when you need it for tax returns, insurance claims, or expense tracking.

- Invoice management for small businesses and freelancers — If you receive invoices or need to keep copies, Attachment Hippo saves them to Google Drive™ as they come in. Rules can be set by sender so documents from specific clients or suppliers go straight to the right folder. Useful for freelancers, sole traders, and small business owners who want their records organised without a complicated system.

- Receipt and expense tracking — Receipts from suppliers, contractors, or online purchases sent by email are saved to Google Drive™ without manual downloading. When tax season arrives, documents are already stored and easy to find. The backfill feature lets you set a past date so that receipts already sitting in your inbox are saved too.

- Contract and agreement storage — Signed contracts, agreements, and proposals received by email are saved to a dedicated folder in Google Drive™ automatically. No need to search through your inbox when you need to refer back to a document.
