Best Win-Back Email Timing: When Should You Contact a Lapsed Customer?
The best win-back email is usually sent after the customer should reasonably have purchased again, but before the relationship has gone completely cold.
That sounds vague.
It becomes much clearer when you use customer data.
Start with median reorder time
Recent ecommerce guidance increasingly recommends using actual reorder data rather than a generic delay.
For example, if the median customer buys again every 45 days, a win-back trigger around 70–90 days may be more defensible than one at day 30. (affinsy.com)
Do not confuse replenishment with win-back
A replenishment message reaches the customer around the time they should need more.
A win-back message reaches them after they have missed that expected purchase.
That difference matters.
If you send a win-back message too early, you risk discounting an active customer.
Use lapse depth
Slightly overdue
Relevance, convenience.
Clearly lapsed
Stronger Return Reason.
Deep lapse
Newness, stronger motivation or suppression decision.
The deeper the lapse, the stronger the reason usually needs to be.
Timing should differ by product
Coffee:
weeks.
Skincare:
often weeks to a few months.
Furniture:
months or years.
A fixed 90-day trigger cannot serve all three.
Search question: “When should I send a win-back email?”
Answer:
Just after the normal purchase window has passed.
That is the cleanest rule.
Frequently asked questions
Is 90 days good timing?
Only if 90 days fits the purchase cycle.
Should I send the first win-back before they are officially lapsed?
That becomes more like at-risk or replenishment messaging. It can be useful, but call it what it is.
When is it too late?
There is no universal cutoff. As lapse deepens, recovery probability and deliverability risk should be reevaluated.
The principle
Timing is not a marketing-calendar problem.
It is a customer-behaviour problem.
