Re-Engagement Postcards: Reach Drifting Customers Before It's Too Late
There's a window between a customer's last order and the point of no return. At 30–60 days of inactivity, a customer hasn't lapsed yet — but they're drifting. Email open rates for this segment drop sharply. A physical postcard arriving in their letterbox is the nudge that brings them back before you need a full win-back campaign. Re-engagement is cheaper, faster, and more effective than win-back because brand affinity is still fresh.
The 30–60 day window
Research from Klaviyo and Retention Science shows that customers who haven't purchased in 30–60 days are 4× more likely to convert with a well-timed offer than customers who have been inactive for 90+ days. At this stage, they remember your brand, they're still reachable, and the cost of re-engagement is far lower than a full win-back effort. Direct mail is particularly effective here because it reaches customers who have mentally filtered out your emails — even if they're still technically subscribed.
How to set up a re-engagement trigger in Mayday
In Mayday, create a campaign with a trigger of 30 days of inactivity (or 45 days if your purchase cycle is longer). Set a suppression window so customers who received a card recently aren't re-triggered. Add a second trigger at 60 days for customers who didn't respond to the first card. This two-step approach mimics the email re-engagement sequences that high-performing brands use, but in physical mail. Filter by minimum order value or segment to focus spend on your most valuable at-risk customers.
What re-engagement postcards should say
At 30–45 days, keep the tone light — a "we haven't seen you in a while" message with a small incentive (free shipping or 10% off). At 60 days, increase urgency: a slightly deeper discount with a firm expiry date. Include the customer's first name and, if your platform allows, reference their last purchase category ("Still looking for skincare?"). A QR code linking to a curated landing page outperforms a generic homepage link by 2–3× in scan-to-purchase conversion.
Results and ROI
Re-engagement campaigns targeting the 30–60 day inactivity window typically achieve 6–12% response rates — higher than traditional win-back campaigns because customer intent is still warm. At Mayday's Growth plan rate of €1.99/card, a campaign sending 500 cards at a 9% response rate (45 conversions) on a €65 average order value returns €2,925 in revenue against €995 in postcard spend — a 2.9× ROI before accounting for lifetime value uplift.
Combining with email for maximum impact
The most effective re-engagement strategy uses direct mail as a complement to email, not a replacement. Send an email re-engagement sequence first. For customers who open but don't convert, or who don't open at all, trigger a postcard at day 45. This layered approach reaches customers across two channels and typically lifts overall re-engagement rates by 30–50% compared to email alone.
