The Domain Health Score in Outboundry is a unified metric that shows the overall health of your sending domain and its ability to land emails in the inbox.
It simplifies multiple complex deliverability signals into a single score (typically from 0–100), helping you quickly understand whether your domain is in good standing or at risk.
A higher score means better email deliverability, while a lower score indicates issues that may cause your emails to land in spam or get blocked.
Your domain’s health directly impacts whether your emails reach your prospects.
Email providers like Gmail and Outlook continuously evaluate your domain reputation based on your sending behavior. If your domain health is poor:
Emails may land in spam
Open rates drop significantly
Campaign performance suffers
In simple terms, your domain health acts like a trust score for your email sending.
Outboundry calculates the Domain Health Score by analyzing key deliverability signals, including:
Proper DNS configuration is critical for trust.
SPF (Sender Policy Framework)
DKIM (DomainKeys Identified Mail)
DMARC (Domain-based Message Authentication)
Missing or incorrect records can negatively impact your score.
This measures how many of your emails are successfully delivered to the inbox vs spam.
Higher inbox placement = better domain health.
Mailbox providers evaluate your domain based on:
Spam complaint rate
Bounce rate
Engagement (opens, replies)
Sending consistency
Poor sending practices can quickly damage your domain reputation.
This reflects the percentage of emails successfully delivered without being rejected or filtered.
A higher deliverability rate contributes positively to your Domain Health Score.
Score Range Status Meaning | ||
80 – 100 | Healthy | Strong deliverability, safe to scale |
50 – 79 | Moderate | Some issues need attention |
Below 50 | Poor | High risk of spam or blocking |
If your score is low, focus on these best practices:
Set up and verify SPF, DKIM, and DMARC
Warm up your email accounts gradually
Avoid sudden spikes in sending volume
Maintain a clean email list (remove invalid contacts)
Improve engagement (better targeting & personalization)
Monitor spam complaints closely
Consistent improvements in these areas will gradually increase your domain health.
Outboundry’s Domain Health Score helps you:

Instead of analyzing multiple metrics separately, you get a single, actionable insight to guide your email strategy.
The Domain Health Score is your single source of truth for email deliverability.
By regularly monitoring and improving it, you can ensure your emails consistently land where they belong — the inbox.
