Frequently Asked Questions

How many emails can I send per day?

Gmail Surge respects Gmail's built-in sending limits. For most Gmail accounts, the limit is around 500 emails per day. Google Workspace accounts may have higher limits. The extension includes configurable daily limit safeguards to keep you safe.

Is my data safe?

Absolutely. Gmail Surge runs 100% in your browser. Your CSV contacts, email content, and credentials are never sent to any external server. Authentication uses Chrome's built-in OAuth flow with Google — no passwords are stored.

What is {{variable}} personalization?

When you upload a CSV with columns like "first_name" or "company", you can insert {{first_name}} or {{company}} into your email. Gmail Surge automatically replaces these placeholders with the actual value for each recipient.

How does the Pro upgrade work?

After purchasing Pro, you'll receive an activation code. Paste it in the Settings tab of the extension and you'll be instantly upgraded to unlimited sending. It's a one-time purchase — no recurring fees.

Does it work with Google Workspace?

Yes! Gmail Surge works with both personal Gmail accounts and Google Workspace (formerly G Suite) accounts. You sign in using Chrome's built-in Google authentication.

Can I include images in my emails?

Yes. The rich text editor supports image insertion via URL or file upload. You can resize images directly within the editor before sending.

Will my emails go to spam?

Gmail Surge sends emails through Gmail's official API, which means they're delivered just like regular Gmail messages. Following email best practices (personalized content, relevant recipients, reasonable volume) will help ensure inbox delivery.
