Common Questions About the Automator

Get Started with Confidence

Using a custom-built extension can feel different from a standard Web Store download. We’ve answered the most frequent questions about the setup, security, and usage limits of the Gmail Bulk Automator to ensure you can start scaling your outreach today with total peace of mind.

Since this is a TechWrath Labs project, you install it via "Developer Mode." Simply download the ZIP, extract it, go to chrome://extensions in your browser, enable the "Developer Mode" toggle, and click "Load Unpacked." Select the folder you extracted, and the tool will appear in your Gmail tab instantly.

Yes. We have capped the list at 100 emails per session to align with Gmail’s natural sending patterns. This helps protect your account's "sender reputation." For the best results and deliverability, we recommend using this for warm leads or verified business contacts.

No. The extension runs entirely locally on your computer. It acts as a script that interacts with your Gmail tab only. Your email addresses, subjects, and message bodies are never transmitted to our servers or stored anywhere outside your own browser.

We host our Labs tools independently to provide the latest versions to our community without the 2-3 week delay of the Web Store review process. This allows us to keep the code "clean" and provide the source ZIP directly to you for transparency.

The current version is optimized for the 100-email limit to ensure stability. If your business requires larger volume automations or a custom CSV-integrated solution, please reach out to us via our Strategy Audit for a custom agency consultation.
