What is Salesforce Mass Email Custom Object?

Custom objects in Salesforce store specialized business data that doesn't fit standard objects like Contacts or Leads. While Salesforce natively supports mass email for standard objects, sending bulk emails from custom objects requires additional configuration.

Universities manage Students, healthcare providers track Patients, real estate agencies maintain Properties, and event companies organize Venues. These custom objects need dedicated mass email capabilities to communicate effectively with their unique audiences while maintaining all custom data structures.

Why Custom Object Mass Email Matters

Most organizations quickly discover that standard Salesforce objects don't meet all communication needs. Native solutions like MassMailer enable mass email functionality for any custom object, eliminating complex workarounds or data migration requirements.

Organizations like Bay Club successfully manage member communications through custom objects, sending event invitations and promotions while maintaining their custom data structures intact.

How to Enable Mass Email for Custom Objects

Step 1: Add an Email Field

Your custom object needs an email field (e.g., "Student Email," "Patient Email"). If missing, you can leverage relationships to objects with email addresses.

Step 2: Enable in Your Email Solution

Native Salesforce doesn't easily support custom object mass email. Configure your custom object in MassMailer by navigating to MassMailer Setup → Email Settings → Object Settings. Detailed setup instructions guide you through complete configuration.

Step 3: Create List Views

Build Salesforce list views to segment your audience: "Graduating Seniors," "International Students," or specific cohorts for targeted campaigns.

Step 4: Design Email Templates

Use merge fields to personalize messages with custom object data—student names, appointment dates, property addresses. Learn how to build templates with merge fields from any object.

Step 5: Send Mass Emails

Select your list view, choose your template, and send. All tracking and reporting functions work identically to standard objects.

Common Use Cases

Education: Universities send course reminders, graduation information, and campus announcements to Student custom objects.

Healthcare: Providers deliver appointment reminders, health campaigns, and patient education from Patient custom objects.

Real Estate: Agencies distribute property updates, open house invitations, and market reports from Property custom objects.

Financial Services: Advisors like HFM send portfolio updates and investment opportunities using custom client objects.

Automation and Advanced Features

Automate mass email sending using Flow Builder when custom object records meet specific criteria. Set up drip campaigns, triggered sequences, and workflow notifications.

Use merge fields from custom objects and parent relationships for rich personalization. Access fields up to six levels up the object hierarchy for sophisticated messaging.

Overcoming Salesforce Limitations

Standard Salesforce faces a 5,000-email daily limit across all objects. MassMailer eliminates daily sending limits while providing full custom object support, comprehensive tracking, and native Salesforce integration without requiring Marketing Cloud.

Retirement Planners of America manages complex custom objects for retirement plans, sending educational content and portfolio updates at scale.
