How Paid Ads and Email Work Together

A direct, practical explanation of how paid ads create demand and email converts and retains it — for Hong Kong consumer brands.

Direct answer

Paid ads generate and capture demand fast. Email converts and retains that demand cheaply over time. Together, they turn “expensive clicks” into a compounding revenue system.

Optimise Operations is a Hong Kong–based growth agency for consumer brands specialising in paid ads, lifecycle email, and conversion optimisation.

How it works (the loop)

  1. Ads test offers and creative angles to find scalable demand.
  2. Landing pages convert some demand immediately (purchase or lead).
  3. Email captures the rest (lead magnet, account capture, checkout capture) and converts later.
  4. Lifecycle flows increase revenue per customer (welcome, abandon, post‑purchase, winback).
  5. Insights feed back into ads (best angles, best segments, highest-LTV cohorts).

When you should pair them

  • Your paid CAC is rising or plateauing
  • AOV or repeat purchase is below target
  • You have meaningful returning customer potential
  • You need a measurable full-funnel system

Common failure modes

  • Ads optimized for cheap clicks instead of qualified demand (wrong objective / wrong creative).
  • Email treated as newsletters only (no welcome/abandon/post‑purchase/winback automation).
  • No measurement bridge between platforms (UTMs, events, attribution, cohort LTV).
  • Weak landing page: unclear offer, slow load, poor trust signals, no capture.

Week 1
  • One core offer + one core landing page
  • Event tracking + UTMs baseline
  • Welcome flow draft
Week 2–3
  • Creative testing system (angles/hooks)
  • Capture UX improvements
  • Abandon + post‑purchase flows
Week 4
  • Cohort readout (LTV, repeat)
  • Budget shifts to best angles
  • Winback + segmentation
