Testing Connections

Before using an SMTP connection in a campaign, verify it's working correctly with Score CRM's built-in test feature.

Sending a Test

1. Navigate to SMTP
2. Find the connection you want to test
3. Click Test Connection
4. Enter a recipient email address
5. Click Send Test

The system will:

1. Initialize the provider with the stored credentials
2. Send a simple test email to the specified address
3. Report success or failure

What the Test Verifies

Check	Description
Authentication	Credentials (API key or username/password) are valid
Connectivity	The SMTP server or API endpoint is reachable
Send Permission	The account has permission to send emails
From Address	The configured sender address is accepted by the provider

Interpreting Results

Success

The test email was accepted by the provider. Check the recipient inbox to confirm delivery.

Failure

Common failure reasons:

Error	Likely Cause	Fix
Authentication failed	Invalid API key or credentials	Update the connection with correct credentials
Connection refused	Wrong host/port	Verify the SMTP host and port
Connection timeout	Network/firewall issue	Check if the SMTP port is open from your server
Sender not verified	From email not verified with provider	Verify the sender domain/email in your provider's dashboard
Rate limited	Too many test emails	Wait and try again

Best Practices

• Test after any credential changes: Always re-test after updating API keys or passwords
• Test before campaign launches: Especially for new or recently modified connections
• Check the inbox: A successful API response doesn't guarantee inbox delivery — verify the test email actually arrived
• Test with a real address: Use an email address you can check, not a dummy address
