Understanding your Contact Health score

The Contact Health score reflects the completeness and usability of your contact records. It's based on five checks, each tied to a different downstream workflow dependency.

Missing Email Address (High Severity)

A contact without an email address cannot receive any email communication from HubSpot — no sequences, no marketing emails, no automated workflows that send email. This is the single most impactful data gap for most teams. If your CRM has a significant number of contacts without emails, a corresponding percentage of your marketing automation is broken.

Missing Name (Medium Severity)

Contacts without a first or last name cause personalization tokens to fail. Any email or template that uses {{contact.firstname}} will render as blank — a visible, unprofessional error. It also makes manual outreach harder for reps who can't easily identify who they're looking at.

Missing Lifecycle Stage (High Severity)

Lifecycle stage is the foundation of funnel reporting and audience segmentation. Without it, you can't accurately measure conversion rates between funnel stages, you can't build stage-based suppression lists, and your marketing team can't segment properly by where someone is in the buyer journey.

No Recent Activity (Low Severity)

Contacts with no activity or modification in 180+ days are likely disengaged or stale. This check helps identify candidates for re-engagement campaigns or, if unresponsive, removal — keeping your contact tier lean and your deliverability healthy.

Duplicate Emails (High Severity)

Duplicate contacts cause double-sends, split activity history, and unreliable engagement data. HubDeck identifies email addresses that appear on more than one record. On Pro, you get the full list of duplicates with both record IDs so you can merge or delete them.
