Frequently Asked Questions
Everything you need to know about Campaign Sender.
How is this a free Gmass alternative?
We keep the workflow lightweight by using Gmail itself as the editing surface and your connected Google account as the sending identity.
How does it integrate with Gmail?
The Chrome extension appears inside compose, extracts the draft data, and hands it to the app for safe individual sends.
Is my data secure and reliable?
Mailbox access is handled through official Google OAuth. Tokens are stored server-side and sends use Gmail APIs instead of brittle browser automation.
Can my whole team use it?
Yes. Each teammate can sign in, connect their own mailbox, and manage their own campaigns from a shared SaaS dashboard.
