Welcome Postcards: Make Every First Purchase Memorable
The first purchase is the most critical moment in the customer lifecycle. Research consistently shows that customers who make a second purchase within 90 days of their first are 3× more likely to become long-term loyal customers. The post-purchase experience — what happens after the order confirmation email — determines whether that second purchase happens. A welcome postcard arriving with or shortly after the first order creates a brand moment that email cannot replicate, and sets the tone for the entire customer relationship.
What makes welcome postcards effective
A new customer's purchase decision involves overcoming risk — they've trusted a brand they haven't bought from before. A physical welcome postcard validates that decision. It signals that the brand is real, invested in the relationship, and values the customer beyond the transaction. It's the digital equivalent of a boutique that hands you a beautifully wrapped package and says thank you as you leave the shop. Brands that send welcome postcards report 20–35% higher second-purchase rates within 60 days, compared to email-only welcome sequences.
Setting up the welcome postcard trigger
Create a trigger in Mayday for customers making their first order, with a 5–7 day delay after fulfilment. The delay ensures the postcard arrives after the product, rather than before it — arriving simultaneously creates a "wow" moment; arriving first can cause confusion. Set a "new customer only" filter to ensure repeat buyers don't receive the welcome card. For brands selling across multiple countries, set up country-specific welcome sequences with localised copy.
What to include in a welcome postcard
Four elements drive the best welcome postcard performance: (1) A genuine, warm thank-you for choosing the brand — not a sales pitch; (2) A brief reminder of what the brand stands for — a values statement or quality commitment; (3) A second-purchase incentive (10–15% off or free shipping on the next order), with a 45–60 day expiry to create a return window; (4) A QR code to a curated "new customer" landing page with your bestsellers or a curated starter collection. Resist the urge to include too much — simplicity converts better.
Sequencing welcome postcards with email
Welcome postcards work best as part of a coordinated onboarding sequence. Day 0: order confirmation email. Day 3–5: shipping update email. Day 5–7: postcard arrives with product. Day 10: post-purchase follow-up email (linking to the postcard offer). Day 30: email nudge referencing the postcard offer expiry. Day 60: win-back trigger if no second purchase. This multi-channel approach drives materially higher 90-day retention compared to email-only sequences.
Industry benchmarks
In e-commerce, 60–70% of first-time buyers never make a second purchase. Brands with strong onboarding sequences (email plus direct mail) reduce this figure to 45–55%. For a brand acquiring 500 new customers per month at an average second-order value of €70, improving 90-day repurchase rate from 35% to 45% generates an additional 50 second purchases per month — €3,500 in incremental revenue. The postcard cost at €1.99/card for 500 postcards is €995/month — a 3.5× ROI from second-purchase uplift alone.
