Listen to: Salesforce Einstein Activity Capture_ The Move to Native Records and Its Impact on Data St

For years, Salesforce administrators and RevOps leaders have had a "love-hate" relationship with Salesforce Einstein Activity Capture (EAC). On one hand, it’s a brilliant tool for automating the logging of emails and calendar events. On the other, the data was historically stored in an external AWS data store, meaning you couldn’t report on it using standard Salesforce tools or use it to trigger automated flows.


That is officially changing. With the Summer ’25 release, Salesforce has introduced “Sync Email as Salesforce Activity.” This update transitions captured emails from an external store into native Salesforce EmailMessage objects and Task records.


While this shift unlocks powerful new capabilities, it also changes the rules of the game for your Salesforce data storage limits. Here is what you need to know to stay ahead of the curve.


Understanding the Shift: How Salesforce Einstein Activity Capture Now Impacts Your Data


Previously, EAC emails were essentially "ghost records." You could see them on the activity timeline, but they didn’t "live" in your org. Because they are now native records, they behave like any other piece of data in your CRM. This brings several immediate benefits:

  • Enhanced Reporting: You can finally use the standard Salesforce Report Builder to track sales engagement, response times, and activity volume.

  • Flow Automation: Since emails are now EmailMessage objects, you can build record-triggered flows to alert managers when a deal stalls or to update a lead status based on a prospect’s reply.

  • API Accessibility: This data is now accessible via API, making it easier to pull into BI tools like Tableau or Power BI for deeper analysis.

As email activity transitions to native storage, organizations risk hitting their Salesforce Einstein Activity Capture storage limits faster than anticipated, leading to unexpected overage costs and performance bottlenecks.

The Hidden Challenge: Managing Your Salesforce Storage Costs


The trade-off for this increased visibility is a significant increase in data volume. In the past, million of emails could sync via EAC without costing you a dime in storage. Now, every single synced email counts against your Salesforce data storage limits.


For enterprise organizations with high-velocity sales teams, this "small" technical change can lead to millions of new records annually. Once you hit your storage cap, Salesforce performance can degrade, and the cost to purchase additional storage blocks is famously high.


Furthermore, once you enable this feature, the change is permanent. You cannot revert to the old external storage model.


Strategic Archiving: How Sesame Software Keeps Your Org Lean


At Sesame Software, we believe that more data should lead to more insights—not a bigger bill. As you prepare to enable native email syncing, an intentional Salesforce archiving strategy is no longer optional; it’s a necessity.


Our patented technology provides a seamless way to balance the benefits of native Salesforce reporting with the need for cost control:

  1. Automated Data Replication: We provide near real-time replication of your Salesforce data—including the new EmailMessage and Task records—to a relational database of your choice (Snowflake, SQL Server, Oracle, or Azure).

  2. Scalable Archiving: Use Sesame Software to move older activity records out of Salesforce and into your private archive. You retain 100% of the data for compliance and long-term analytics but keep your Salesforce production environment lean and fast.

  3. Predictable Flat-Rate Pricing: Unlike many Salesforce backup and recovery tools that charge "per GB" or based on record counts, Sesame Software offers a flat annual fee. You can scale your email volume infinitely without ever worrying about a surprise invoice.

The Bottom Line


The move to native email records is a win for the Salesforce ecosystem, signaling a shift toward more transparent and actionable data. However, the teams that succeed will be those that treat the new Salesforce Einstein Activity Capture update as a strategic data lifecycle project rather than a simple feature toggle. Before you flip the switch, it is critical to evaluate your current storage footprint and ensure you have a robust data management and backup solution in place to handle the rapid growth of these native records.
