Customer Retention Case Studies

We've seen engagement rates and repeat purchases go through the roof all thanks to a little thoughtfulness handwritten onto a notecard. Take a look to see what marketing teams are achieving with the power of the pen.

Case studies are anonymised because our clients like to keep us a secret!

Welcome new customers and increase CLV

For 3 years we have sent an Inkpact to new customers of a designer men’s swimwear brand… The goal was to welcome new customers, thank them for their purchase and increase repeat purchases. The brand ran an A/B split test measuring the impact of handwritten notes vs email to see if the added thoughtfulness would make a difference… and it did… 

The results


Increase in average order size


Increase in repeat purchase rate


Increase in revenue
Handwritten welcome note

Seasonal offer to increase repeat purchases

We sent handwritten Valentines Day cards to a gym apparel company’s customers. We wanted to test the impact of handwritten mail vs printed mail - the campaign was A/B split tested. The same message was sent to every recipient but half received a handwritten card and half a printed card. The goal was to drive redemptions of a discount code.

The results


Redemptions from our handwritten note



Redemptions from their printed DM campaign
Folded cards

Our members are everything to us. With Inkpact we can show them how much we value them in a way that is in keeping with and enhances our brand. Our customers love the personal touch that a handwritten note brings.
