Halden & Rowe · Ireland · Digital
Irish digital customers respond twice as strongly to weekly cadence as to weekend bursts — the UK pattern does not port.
The Irish digital cohort is not a small UK. It reads promotional cadence differently, and the current CRM calendar treats it as a scaled-down version of the UK.
Observation
The pattern.
What Ana has read in the trading data — described in the language a senior analyst would use with the CEO.
Testing the last twelve promotional windows in Ireland against matched UK windows, the Irish cohort delivers 2.1× the response rate when a promotion is delivered as a weekly Tuesday cadence versus a Friday-to-Sunday burst. The UK cohort shows the inverse preference at 1.4× the response rate for the weekend burst. The pattern holds across category, price band, and loyalty tier, and is stable across the last four seasons.
Evidence
What Ana is reading.
Five to six pieces of supporting evidence. Each line is a signal, its measurement, and — where useful — a caveat.
Irish response — Tuesday weekly
2.1× the response rate of weekend burst
Trailing twelve windows, matched offers
UK response — same test
1.4× stronger for the weekend burst
Same trailing period, matched offers
Category stability
Effect present across every top-ten category
So not a range artefact
Loyalty-tier stability
Effect present across gold, silver, and bronze cohorts
So not driven by any single tier
Seasonal stability
Pattern present in every quarter over the last four seasons
Not a summer effect
Current calendar mix
82% of Irish sends currently sit inside the weekend window
So we are structurally on the wrong side of the pattern
Why this matters
What changes if leadership takes this on board.
The business consequence, framed for a board conversation rather than a metric review.
We are treating Ireland as a scaled-down UK, and it is costing roughly €27,000 a month in response the Irish cohort is willing to give — every send that lands on a Friday is a send an Irish customer would rather answer on a Tuesday. Correcting it is a scheduler change, not a campaign redesign, and the recovered revenue lands inside the FX Mission on the same country.
Commercial framing
The order of magnitude.
An honest sizing of the pattern, with the methodology stated so the number can be argued with.
Order of magnitude
€320K
incremental Irish digital revenue at the corrected cadence · next 12 months
How Ana arrived at this number
Move 60% of Irish sends into a Tuesday cadence; apply the 1.7× cadence-corrected uplift to current campaign revenue.
Counter-evidence
The reasons the pattern might not generalise.
The caveats Ana would raise before an executive commits an Insight to a decision. Included by design — an Insight is only useful when its limits are known.
Send-volume asymmetry
Fatigue may be inflating the delta; correcting for cadence saturation reduces it to 1.7×
Weekend Irish sends carry twice the frequency of Tuesday sends
Population size
Statistical power is fine but confidence intervals are wider
Irish cohort is 14% the size of the UK cohort

Ana's commentary
How Ana would present this in the room.
The Irish cohort has been treated as a scaled-down UK for as long as the calendar has existed. This Insight does not need a campaign; it needs a scheduler change. The cost of testing is negligible; the cost of continuing is roughly €27,000 a month at current cadence.
Recommended monitoring
What Ana will keep watching.
The signals whose movement would either confirm the pattern is holding or tell us it has stopped.
- 01
Response rate on Irish sends by day-of-week, monthly, held against the UK baseline.
- 02
Fatigue signal — unsubscribe and complaint rate as the Tuesday cadence takes share.
- 03
Cross-cohort read once the loyalty silver reactivation lands in week 29, so the two mechanics do not confound.
