GuestPostCRM Gmail OAuth Scopes

Understanding our integration permissions and data usage

Last Updated: 28th November, 2025

This page describes the exact Google OAuth scopes requested by GuestPostCRM when you connect your Gmail account.

1. Why We Request Scopes

GuestPostCRM requires certain Google API permissions to perform:

Email Syncing

Real-time Inbox Updates

Classification & Labeling

Workflow Automation

Sending Emails

Tracking Communication

We request only the minimum scopes needed for the system to function reliably.

2. Scopes Used by GuestPostCRM

GuestPostCRM may request the following Google OAuth scopes:

a. gmail.readonly

Used for reading email metadata and retrieving messages related to outreach, follow-ups, and CRM entries.

b. gmail.modify

Used for:

Classifying emails
Moving messages between internal system labels
Creating CRM-specific labels such as Non-Relevant Content, Spammy Content, No Reply, and Duplicate

c. gmail.send

Used for sending automated messages, follow-ups, or templates — but only when explicitly triggered by the user.

d. userinfo.email

Used to verify the connected Gmail account and associate it with the correct workspace.

e. pubsub (Google Pub/Sub API)

View and manage Pub/Sub topics and subscriptions.

Used for enabling faster, more reliable, and real-time Gmail synchronization.

This allows GuestPostCRM to receive instant notifications when new messages arrive, reducing sync delays and improving inbox classification accuracy.

3. How These Scopes Are Used

These permissions allow GuestPostCRM to provide:

Real-time lead and inbox syncing
Email classification based on CRM workflows
Logged communication for deals, orders, and client records

Automatic label creation and management
Accurate tracking of outreach and follow-ups

Only email data directly relevant to CRM operations is processed.

4. No Sensitive Data Use

GuestPostCRM does not access:

Emails categorized as “sensitive” by Google
Bank information, passwords, or financial emails

Personal communication unrelated to business use
Any private data beyond what is required for CRM automation

We do not use Gmail data for advertising or profiling.

5. Revoking Permissions

You may revoke Gmail access at any time by visiting your Google Account → Security → Third-party Access.

Upon revocation, syncing and Gmail-related features inside GuestPostCRM will stop immediately.
