1. Overview

User permissions in MassMailer control access to features, data, and automation capabilities within Salesforce CRM.

Non-MassMailer users require specific permissions to interact with MassMailer-driven automation like Flows and Process Builder.



2. Purpose

Enable permissions for non-MassMailer users to:

  • Execute email automation via Flows or Process Builder

  • Access MassMailer Apex classes

  • Use Visualforce components

  • Support backend automation without full license access

3. When to Assign Permissions

Assign the MassMailer Non-User Permission Set when:

  • Flows send emails using MassMailer

  • Flows perform email verification

  • Process Builder triggers MassMailer actions

  • Users interact indirectly with MassMailer features

4. Permission Model

4.1 Permission Sets

  • Recommended approach

  • Configurable under App Permissions

  • Flexible and reusable

4.2 Profiles

  • Alternative approach

  • Managed via Enhanced Profile UI

5. Configuration Steps

6. System Behavior

  • No access to full MassMailer UI unless licensed

7. Best Practices

  • Use permission sets instead of profiles

  • Assign only required access (principle of least privilege)

  • Regularly audit assigned permissions

  • Test flows after permission changes
