What to Do When Your Health Score Drops
If your mailbox Health Score drops significantly, follow these steps to diagnose and recover.
Step 1: Check Your Mailbox Connection
Go to your mailbox settings and verify the connection status is 'Connected'. A disconnected or expired OAuth token means warmup emails cannot be sent or received, which will cause your score to drop.
Step 2: Verify DNS Records
Check that your SPF, DKIM, and DMARC records are correctly configured in your domain's DNS settings. Missing or misconfigured DNS is the most common cause of sudden score drops. Use the Analytics page to verify your DNS setup.
Step 3: Review Bounce Rate
A spike in bounces (above 5%) strongly impacts your score. Common causes include:
• DNS records changed or removed.
• Mail server configuration issues.
• Sending to outdated or invalid email addresses in campaigns.
Step 4: Pause Campaigns Temporarily
If your score is below 50, consider pausing active campaigns until your score recovers above 60. Campaign sends with a damaged reputation will have poor deliverability and can make the problem worse.
Step 5: Let Recovery Mode Work
If the system has auto-switched your mailbox to Recovery mode, do not override it. Recovery mode reduces daily volume and focuses on rebuilding your reputation through carefully managed warmup sends. Most mailboxes recover within 2-4 weeks.
Step 6: Monitor Daily
Check your score daily during recovery. Look for a steady upward trend. Small daily fluctuations are normal — focus on the 7-day trend rather than individual days.
When to Contact Support
