Learn how to move beyond standard auto-responders by connecting Salesforce Agentforce to Email-to-Case for autonomous, data-grounded email resolution.

Why This Use Case Matters

In the Salesforce ecosystem, we are constantly looking for the "Great Transfer"—that specific application where AI moves from a demo to a genuine business driver. For many organizations, that moment is Autonomous Email Resolution.

The Problem: The Traditional Email-to-Case Grind

Repetitive Tasks: Reps spend hours answering basic policy or "how-to" questions already documented in Knowledge.
The Latency Trap: While agents handle simple inquiries, high-priority cases sit in the queue, increasing Average Handle Time (AHT).
Static Responses: Standard auto-responders only acknowledge receipt; they don't solve the user's problem.

The Solution: From Deflection to Resolution

Grounded Knowledge: The agent pulls context-aware answers directly from your Agentforce Data Libraries.
Autonomous Action: It can trigger Salesforce Flows (e.g., generating a visitor invitation pass) directly from an email.
Contextual Escalation: It intelligently hands complex cases to humans with a full summary.

🛠 Technical Configuration: Step-by-Step Guide

1. Ground the Agent with Data Libraries

Go to Setup → Einstein → Agentforce Data Library.
Click New Library and upload your Knowledge files or PDFs. This ensures the agent provides grounded answers based on your specific organizational truth.

2. Set Up the Lightning Email Template

Create a new Lightning Email Template (Classic is not supported). You must include these placeholders:

[[[GENERATED_CONTENT]]] — Where the AI inserts its answer.
[[[LEGAL_DISCLOSURE]]] — Where the AI disclaimer appears.

Leave the subject blank. Emails sent using the template will use this subject format: RE: (Subject of the customer’s initial inquiry).

3. Build the Agentforce Service Agent

In Setup, create a new Service Agent. Assign relevant Topics. Important: Go to the Connections panel and click "Turn It On" to manage the agent across channels.

Note: Remove any "Verify Identity" topics, as User Verification is not currently supported on the email channel.

4. Configure Agentforce for Service on Email

Bridge the gap between your Agent and the email channel.

In Salesforce Setup, navigate to Agentforce for Service on Email.
Click New Configuration.
Assign this configuration to your specific Agentforce Service Agent and select the Email Template created in Step 3.

5. Link Configuration to Email-to-Case

Return to your Email-to-Case settings.
Edit your Routing Address.
Locate the section labeled Agentforce Service Agent Settings.
Select the Email Configuration you created in Step 5.

6. Define the Routing Logic

The Agent must own the Case to process it. You can use an Omni-Channel Flow (Route Work to Agent), Case Assignment Rules, or set the Default Case Owner on the Routing Address to the Agent User (EinsteinServiceAgent).

🚀 Pro-Tip: Initiating the Conversation via Flow

One of the powerful features of Agentforce for Email is the ability to trigger the Agent to start the conversation.

The Feature: You can trigger the Agent to start a conversation using a Salesforce Flow. Instead of waiting for an email, you "loop" the agent in by assigning it Case ownership and sending an initial email. Any reply from the customer then triggers the Agent to handle the triage autonomously.

Example Scenario: An order is delivered. A Flow creates a Case, assigns it to the Agent User, and emails the customer to offer help. When the customer replies asking about the return window or setup, the Agent answers the question using your Knowledge base, resolving the inquiry before it ever reaches a human queue.

You can trigger the Agent to start the conversation proactively:

Create Case & Assign Owner: Create a Case and set the owner to the Agent User.
Send Email via Flow: Use a "Send Email" action.
Threading: You must include the Email Threading ID in the body/subject and set the Related Record ID to the Case ID.
Org-Wide Addresses: The initial email must be sent from the same address configured in your Email-to-Case routing, or the reply won't find its way back to the Agent.

⚠️ Key Considerations & Limitations

[!IMPORTANT] Technical Constraints:
Text Only: Agentforce cannot read images or PDF attachments; it only processes the email body and subject.
Recipient Limit: "Reply All" is limited to 20 recipients total (To + CC).
Daily Limit: Default limit is 5,000 transactions per day.
No User Verification: Ensure you remove "User Verification" topics specifically for the email agent to avoid errors.
The Automated Case User (found in Support Settings) must be set as a System User or a user with "Customize Application" permission. If this isn't set, the Agent might not have the "authority" to process the inbound email logic.

[!NOTE] Escalation & Monitoring:
The "Technical Why": Always configure an Escalation Topic. If the agent hits a runtime error (like a logic loop), it automatically creates a Case Comment with the error details and reassigns the case to the human Default Case Owner. This is your primary way to monitor for failures.

[!TIP]
Testing: The Agentforce Builder preview is a chat-based interface. To view the actual email layout and applied templates, you must test by sending a real email to the routing address.
You can also pass a message like the following in the preview and include the Case ID to simulate the flow. This is not as accurate as real email testing, but it can help when validating small or newly added features:
Message:
(### Respond to the following email in standard email format, greeting the recipient by name when known. Address the user's actual question only, ignoring signatures or disclaimers. Use only known details with no placeholder text. Ensure your response aligns with a professional business tone, is clear and concise, and does not assume or invent any information beyond what is explicitly provided in the email or available context.)
