Why Contacts Disengage — and What It Costs

From Dormant to Delighted - Automatically

360-Degree Contact Profile

Every email, click, purchase, WhatsApp reply, site visit, and CRM update visible in a single chronological contact timeline — giving you the full picture of every relationship.

Engagement Scoring

ClusterZap calculates a real-time engagement score for every contact across all channels. Scores rise with engagement, fall with inactivity — giving you an objective health metric for every relationship.

Lifecycle Stage Automation

Contacts move automatically between lifecycle stages — new, active, loyal, at-risk, dormant — with appropriate, personalised campaigns triggered at each transition.

Dynamic Segmentation

Build audiences that update in real time based on engagement score, lifecycle stage, purchase behaviour, channel preference, and any CRM data point.

Re-Engagement Campaigns

When a contact's score drops below a defined threshold, ClusterZap automatically launches a personalised win-back sequence across email, WhatsApp, and SMS — before the relationship is lost.

Proactive Engagement Alerts

Get notified when a key account or high-value customer shows declining engagement — so your team can intervene personally before automation alone is not enough.

Personalisation at Scale

Every communication is personalised using the contact's history, preferences, behaviour, and stage — not just their first name.

Channel Preference Management

ClusterZap learns which channel each contact prefers to engage on and prioritises that channel — maximising response rates across your database.

Frequently Asked Questions

Engagement is scored based on recency, frequency, and depth of interaction across all tracked channels — email opens, clicks, WhatsApp replies, site visits, purchases, and app activity. You define what 'engaged' means for your business.
When a contact's engagement score falls below a defined threshold — or when they have had no tracked activity for a defined number of days — ClusterZap automatically triggers a personalised win-back sequence.
Yes. Automated lifecycle transitions can be overridden by any team member, and manual stage changes trigger the appropriate campaign sequence just as automation would.
Email marketing is one channel. Contact engagement is a cross-channel relationship management discipline — using email, WhatsApp, SMS, push, and in-app in coordination, driven by a unified contact profile and engagement score.
ClusterZap attempts to re-engage through any valid channel in the contact's profile — SMS and WhatsApp can reach contacts even when email addresses are invalid or undeliverable.
