FAQ

Questions teams ask first

What revenue, security, and finance want to know before they start.

How quickly will we see results?

Most teams see deliverability and engagement lift within the first few weeks, as we validate data and tighten sending. Retention and net-revenue impact compound over the first one to two quarters as lifecycle flows and churn-risk signals mature.

Does it fit our existing stack?

Yes. We connect to your CRM, data warehouse, and BI tools through native integrations, webhooks, and a REST API — so retention signals flow into the systems your team already uses, with no rip-and-replace.

How is our customer data handled?

Data is encrypted in transit and at rest, access is role-restricted, and we operate under a signed Data Processing Agreement aligned with the GDPR. We act as your processor, you remain the controller, and your data stays yours.

What do we actually get?

A managed retention engine: validated data, lifecycle email and SMS, deliverability monitoring, churn-risk signals, and NRR reporting — backed by a real retention strategist, not just a dashboard.

Do you work with our team or replace it?

We work alongside you. Think of us as an extension of your revenue team: we bring the tooling, deliverability discipline, and retention playbooks, while you keep ownership of strategy and brand.
