Definition
Test Deliverability is a Setup tool that sends a test email from Salesforce to a specified address to verify that outbound email delivery is working correctly. It helps administrators diagnose email deliverability issues by confirming that emails can successfully leave the Salesforce platform and reach recipients.
In plain English
“Here's a simple way to think about it: Test Deliverability is the simplest tool for confirming email actually leaves the org. Click a button, supply an address, Salesforce sends a real email. The 30-second answer to whether the platform is even sending mail.”
Worked example
After configuring email relay through the company's Exchange server, the admin at Apex Dynamics uses Test Deliverability to send a test email to her personal Gmail account. The test email arrives within 30 seconds, confirming that the relay is properly configured and emails are flowing from Salesforce through Exchange to external recipients.
Why Test Deliverability is the simplest tool for confirming email actually leaves the org
When email isn't arriving - the workflow alert that didn't fire, the password reset that didn't show up, the Apex .send() that returned success but produced silence - the question is whether Salesforce sent the message at all. Test Deliverability cuts through that ambiguity. Click the button, supply an address, Salesforce sends a real email, you check your inbox. If the test arrives, the platform's outbound stack is healthy; if it doesn't, you've localized the problem.
The reason it earns a place in every admin's debugging toolkit is the speed of the answer. Most other email-deliverability questions take long support cases or DNS investigations to resolve; Test Deliverability resolves the foundational question of whether the platform is even sending mail in 30 seconds. Run it any time email seems flaky, and run it after any change to Deliverability or Email Relay settings to confirm the change didn't break anything obvious.
How organizations use Test Deliverability
Used Test Deliverability after Email Relay configuration to confirm relay was working; caught a misconfiguration immediately.
Routine email-troubleshooting starts here; localizes the problem to platform vs. integration vs. recipient.
