One record.Every signal.Every list.
OneTrueList builds and maintains a single, verified contact record inside WordPress — reconciled across every ESP you run, enriched by every reply, OOO, and bounce your mailboxes receive.
No duplicate imports. No stale job titles. No list sprawl.
Your contact data is older than you think.
Every ESP has its own version of the same person. Different job titles. Different companies. Last updated whenever they last filled in a form.
Meanwhile, your mailboxes receive hundreds of signals every week — out-of-office replies with new job titles, signatures with direct dials, auto-responders naming a successor — and none of it feeds back into your records.

The work your CRM isn't doing.
OOO Intelligence
OTL parses every OOO your mailboxes receive — extracting job titles, phone numbers, LinkedIn profiles, and cover contacts from the reply body. Every extraction updates the contact record. Every correction is logged.
Identity Resolution
Four-tier matching: LinkedIn numeric ID first, then email, then name and company, then AI-assisted review. Company names normalised against Companies House. Job title variants mapped to function and seniority bands. Conflicts flagged for review, not silently merged.
ESP Sync
OTL connects to your ESP and pulls contact data into a single WordPress-native record. When data conflicts between sources, OTL applies source hierarchy rules you control — not arbitrary last-write-wins logic.
Domain Intelligence
OTL resolves business domains to company records — sector, size band, Companies House number, SIC code. No third-party enrichment subscription required for UK B2B data. Updated from public sources on a schedule you set.
Works with the ESP you already use.
OTL is built around an open connector architecture. Each ESP gets a dedicated connector handling field mapping, sync direction, and conflict resolution. Install only what you need.
Don't see your ESP? Connectors are open for development.
Your contact records are a decision.
You can keep running separate lists in separate ESPs and reconciling them manually every quarter. Or you can install OTL and let the replies do the work.
