Salesforce Email Limits refer to daily sending restrictions imposed on email communications from the platform. The primary constraint is 5,000 mass emails per organization per day, shared across all users regardless of edition or company size.
How It Works
Salesforce tracks email volume at the organization level using a 24-hour rolling window. Emails sent through mass email features—campaigns, list emails, Process Builder actions, and Apex mass email API calls—count against your allocation. Single emails sent from individual contact records have a separate 5,000 per user limit.
The counter resets on a rolling basis, not at midnight. An email sent at 11 PM counts against capacity for 24 hours. There's no real-time dashboard showing remaining capacity—administrators must check email logs, which lag by hours.
Key Limitations
The 5,000 limit creates immediate scaling problems. A 50-person sales team sharing this cap gets just 100 emails per person daily. One marketing campaign to 5,000 contacts exhausts the entire day's capacity, blocking all other email operations. Companies can't purchase additional capacity at any price point—the limit is architectural.
Campaign fragmentation becomes necessary for larger sends. A 15,000-person newsletter requires three days, destroying timing and urgency. Time-sensitive announcements lose impact when staggered over multiple days.
Solutions
Optimize targeting by segmenting lists and sending only to engaged contacts. A 5,000-person engaged list outperforms a 10,000-person disengaged list while using less capacity. Schedule campaigns throughout the day rather than front-loading at 9 AM to maximize utilization.
For teams consistently hitting limits, MassMailer extends Salesforce with unlimited daily sending while maintaining native CRM integration. Unlike ESP integrations requiring data syncing, it operates directly within Salesforce, letting you scale without architectural complexity.
