Thank You Notes Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Sharpie is the best-performing thank you notes brand in July 2026, moving 50,000 units across 1 ASIN for 54.3% of Top 10 volume. SPIRITDUST follows with 20,000 units (21.7%), ahead of Hallmark on 8,000 units (8.7%).

With 7 brands splitting the Top 10 and 84.8% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $6.49 to $10.37, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0B5RBFL7S booked 3K units at $6.99, with ▲ 50.0% MoM change. On the growth side, B0CZVTWGWG leads positive momentum with ▲ 900.0% MoM growth on 500 units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
