Real-time Salesforce sync
The key difference between Mixmax vs Outreach for Salesforce CRM users is that Mixmax's real-time sync lets your workspace reduce the number of Salesforce Bulk API calls and retrieve close to real-time updates from Salesforce. By contrast, Outreach creates a duplicate database inside the platform, which causes data silos. The CRM integration is also notoriously buggy and can cause duplicate records or failure to record activity.
