Salesforce keeps every customer conversation in one place. Sales emails, support replies, case updates, attachments, long threads. Over time, these emails quietly pile up inside your org. What most teams don’t realize is that EmailMessage records and attachments can end up consuming a huge portion of Salesforce storage. When email data keeps growing, the effects start showing up everywhere. Reports take longer to run. This is exactly where Salesforce email archiving becomes important.
In this blog, we’ll look at why email storage grows so quickly in Salesforce, when emails should be archived, and how Salesforce email archiving helps keep your org clean, fast, and easier to manage.
Why Emails Consume So Much Salesforce Storage
Emails grow inside Salesforce faster than most teams expect. Every sales conversation, support reply, case update, and attachment gets stored as a record. Over time, these records quietly pile up and start consuming a large portion of Salesforce email storage.
Let’s look at the main reasons email data grows so quickly.

EmailMessage Records in Salesforce
Salesforce logs emails using the EmailMessage Salesforce object. Every email linked to a lead, contact, opportunity, or case becomes a separate record. For active sales and support teams, this quickly turns into thousands or even millions of records.
Email Attachments and Files
Emails often include attachments like contracts, PDFs, screenshots, and reports. These files are stored in Salesforce and usually take up more space than the email itself. When thousands of emails contain attachments, Salesforce email storage grows rapidly.
Long Email Threads
Customer conversations rarely happen in a single email. Long threads with multiple replies create several EmailMessage Salesforce records, each storing repeated content and large HTML bodies.
Marketing Cloud Email Data
Organizations using Marketing Cloud generate even larger volumes of email activity through campaigns, newsletters, and automated journeys. Without a proper email archiving Salesforce Marketing Cloud strategy, campaign history, and engagement data can grow quickly.

Understanding Salesforce Storage Limits for Emails
Salesforce storage fills up faster than most teams expect, especially when emails and attachments start accumulating.
Here are the numbers every admin should know:
| Storage Type | Default Salesforce Limit | What Consumes It | Why It Matters |
|---|---|---|---|
| Data Storage | 10 GB base + 20 MB per user | EmailMessage records, email body content, metadata | Large volumes of email records quickly increase Salesforce email storage and push orgs toward Salesforce storage limits |
| File Storage | 10 GB base + 2 GB per user | Email attachments like PDFs, screenshots, reports | Attachments are usually the biggest reason teams hit storage limits |
| Email Volume | Support teams can generate 10,000+ emails per month | Each email becomes an EmailMessage Salesforce record | Over time, this creates millions of records |
| Attachment Size | Typical email attachment 1–10 MB | Contracts, logs, screenshots, documents | File storage fills much faster than expected |
When email records and attachments keep growing, many organizations eventually hit the storage limit exceeding the Salesforce warning.
How Archiving Emails in Salesforce Improves Org Efficiency?
We are aware that, as CIOs, IT Directors, or Salesforce Admin Heads, you must have already heard of saving Salesforce space by offloading emails externally, but that’s not all you want.
Here’s how you can achieve it:
Reduces Storage Overhead & Cost Burden
Archived emails are offloaded from expensive Salesforce storage to external, low-cost platforms like AWS, Azure, or on-prem servers. This frees up Salesforce space for mission-critical data and significantly lowers recurring storage costs.
Keeps Salesforce Running Faster
Overloaded orgs suffer from slow searches, delayed queries, and longer load times. Archiving removes old, inactive emails, keeping the CRM lightweight and optimized for active users, improving system speed and employee productivity.
Ensures Regulatory & Compliance Readiness
Enhances User Experience in Salesforce
Strengthens Customer Trust with Reliable Records
Archived emails act as a single source of truth for customer communication history. During disputes or service escalations, teams can quickly retrieve older emails, leading to faster resolutions and improved customer satisfaction.
Frees IT Teams from Manual Data Management
Without archiving, IT teams spend hours managing storage, exporting emails, or firefighting performance issues. With automated archiving, admins can focus on strategic projects instead of manual cleanup.
Improves Collaboration Across Teams
Archived emails remain searchable and accessible across Salesforce, meaning sales, legal, and compliance teams can collaborate seamlessly without duplicating records or exporting data outside the system.
Builds a Future-Proof Data Strategy
As email volumes grow exponentially, businesses risk Salesforce becoming a storage dump. Archiving creates a scalable, long-term data management strategy, ensuring Salesforce remains performance-ready for future growth.
Lowers Risk of Data Loss or Accidental Deletion
Native deletion or mismanagement of email records can lead to permanent loss. Archiving ensures every email is securely stored, backed up, and retrievable, minimizing business risks tied to lost communication.

Ways to Archive Historical Emails in Salesforce
Instead of deleting old data, businesses should implement file and email message archiving together. This ensures:
- Sensitive content is retained securely.
- The email record context is preserved.
- Email storage costs are minimized.
- Searchability is maintained via indexed formats.
- Identify old EmailMessage records: Find emails linked to closed cases, completed opportunities, or inactive records that no longer need to stay in the main org. These are ideal candidates for Salesforce email archiving.
- Segment email data: Classify emails into active, semi-active, and inactive categories so it’s easier to decide what should stay in Salesforce and what should be archived.
- Apply clear retention policies: Many organizations keep the latest 12 months of emails active and archive older records based on compliance or operational needs.
- Automate archiving policies: Instead of manual cleanup, schedule automated jobs to Salesforce archive email messages regularly and control Salesforce email storage growth.
- Use scalable storage: Move inactive emails and attachments to cloud email archiving storage like Big Objects or external systems to avoid rising Salesforce storage pricing.
- Keep archived emails accessible: Ensure archived emails remain searchable and linked to Accounts, Cases, and Opportunities so teams can still retrieve them when needed.
Conclusion
As email communications expand rapidly, relying solely on Salesforce’s native storage capacity can cause performance issues, downtime, and high storage costs.
Whether you’re archiving emails, handling Salesforce Marketing Cloud operations, or working toward compliance with marketing cloud email archiving, now’s the time to make email archiving storage a priority.
