CRM Lead Enrichment & Cold Outreach Engine — architecture overview

01 — The problem

Cold outreach fails twice over: on bad data, and on generic copy. Sending to unverified addresses damages domain reputation, and templated mail gets ignored by the addresses that do work.

02 — Our solution

Fix the data first, then the message. Companies and contacts are upserted so the CRM stays the single source of truth, deliverability is scored before send, and only surviving records get a personalised email generated from what is actually known about them.

Architecture

How it works

The pipeline, step by step — from the first input to the final output.

  1. 01

    Batch intake

    Lead records are processed in batches rather than one at a time.

  2. 02

    Upsert

    Companies and contacts are created or updated so no duplicate records accumulate.

  3. 03

    Deliverability scoring

    Each address is scored before it is ever mailed.

  4. 04

    Personalised generation

    First-contact emails are generated per contact from enriched context.

Engineering notes

Challenges we solved

Protecting sender reputation

One bad list can damage a domain for months. Scoring before send is a cheaper insurance than any recovery process.

Personalisation needs real inputs

Generated copy is only as specific as the enrichment behind it — which is why enrichment runs first.
