Limitations & Usage Notice

This tool is designed for light to moderate use — ideal for individuals who want to download attachments from labeled Gmail threads into Google Drive in small-to-medium batches.

Due to Google Apps Script limitations on free Gmail accounts:

• Total script usage is capped at ~90 runs per day
• Each run must complete within 6 minutes
• The total amount of data written to Drive is limited to ~30–50MB per day

If you're attempting to download hundreds of large attachments, or bulk-process your entire inbox, this tool may not be suitable for your needs.

Best for:

• Virtual assistants
• Solo professionals
• Coaches, consultants, or realtors saving client files
• Anyone looking to automate small daily workflows
  

Using a Google Workspace Account?

If you're on a Google Workspace (paid) account, this tool becomes significantly more capable.

Here’s how your limits increase compared to free Gmail:

Workspace Upgrade Benefits

1. Script execution limit:
   From ~90 runs/day → Up to 1,500 script runs/day
2. Script runtime per execution:
   From 6 minutes → Up to 30 minutes per run
3. Total script time per day:
   From ~30 minutes → Up to 6 hours/day
4. Drive data upload limit:
   From ~30–50MB/day → Up to 10GB/day
5. Drive file creation limit:
   From ~100 files/day → Up to 1,000+ files/day

These increased limits allow power users to batch-process hundreds of emails and attachments, process larger files, and run the script more often — without hitting Google’s quotas.
