Salesforce Email Limitations Per Day encompasses two separate daily restrictions: 5,000 mass emails per organization (shared across all users) and 5,000 single emails per user. Understanding the distinction between these limits is essential for effective email planning.

The Dual Limit Structure

Mass email limit (5,000 per org): Applies to bulk features—campaigns, list emails, mass API calls, automated workflows. This organization-wide pool is shared by everyone. A 100-person team has the same 5,000 capacity as a 10-person team.

Single email limit (5,000 per user): Applies to emails sent from individual contact/lead records. Each user gets their own allocation. A 50-person team theoretically has 250,000 combined single email capacity.

The determining factor is which Salesforce feature sends the email, not the recipient count. Sending to 50 people from a list view uses 50 mass emails. Sending manually to 50 people from contact records uses 50 single emails from your personal quota.

Key Challenges

The organization-wide mass email limit creates the binding constraint. Marketing campaigns, sales prospecting, and customer onboarding all compete for the same 5,000 capacity. A single marketing campaign exhausts organizational capacity, blocking all other operations.

Single email functionality lacks efficiency for bulk sending. Reps sending the same message to 100 prospects must either use mass email (shared pool) or manually send 100 times (time-consuming).

Managing Both Limits

Map workflows to appropriate channels. Route bulk communications through mass email deliberately. Reserve single emails for truly personalized one-to-one communication.

Create organizational sending calendars. Marketing blocks capacity for campaigns, sales reserves slots for prospecting, customer success schedules onboarding. This prevents conflicts and ensures critical sends complete.

For teams hitting organizational mass email limits consistently, MassMailer eliminates this constraint.

Send unlimited mass emails daily while single email limits remain (they're rarely binding).
