The warmup health score measures the percentage of your warmup emails that landed in the inbox versus spam folders, based on the last 7 days of warmup activity.
Go to the Email Accounts dashboard
Find "Health Score" column
Aim for warmup health score above 90%
How Warmup Health Score Is Calculated
Health Score = (Warmup emails in inbox ÷ Total sent warmup emails) × 100
Check the "Warmup Emails" column in the Email Accounts dashboard. This shows emails sent in the last 7 days
Check the 'X saved from spam' in the warmup analytics
Total emails - Spam emails = Inbox emails
Calculate percentage:
Warmup emails sent (7 days): 80
Landed in spam: 1
Landed in inbox: 79
Health Score: (79 ÷ 80) × 100 = 98.7%
How to Improve Low Health Score
A low health score during the early stages of warmup is completely normal. As your accounts warm up, our system introduces new recipient accounts that haven't interacted with yours before, resulting in some warmup emails naturally landing in spam initially.
Our system automatically moves these emails from spam to the inbox, gradually building your sender reputation over time.

Reputation builds gradually
Why Is My Health Score at 0?
New accounts: If you just enabled warmup, accounts start sending warmup emails after 12 AM UTC the next day. Until warmup emails are sent, the score will remain at 0.
No recent activity: The health score only reflects the most recent 7-day period. If no warmup emails were sent in the last 7 days, the health score automatically resets to 0.
