How Many Mailer Boxes Should You Order?

06/19/2026

Ordering too few mailer boxes means a mid-launch scramble to a generic backup box; ordering too many ties up cash and warehouse space in packaging. The good news: mailer box quantity math is simple once you know your average daily order volume.

The basic formula

Take your average number of orders shipped in this box style per day, multiply by 30 for a month of coverage, and add 15–20% for a launch or holiday spike. Most new DTC brands land comfortably inside our 100-box minimum for a first order.

Business size Typical monthly boxes Suggested first order
New DTC brand 100–500 100 (minimum)
Established single-SKU brand 500–2,000 1,000–1,500
Multi-SKU / multi-warehouse 3,000–10,000 5,000–8,000
High-volume subscription / wholesale 15,000+ 15,000–25,000

Account for seasonality

Q4 and major sale events (BFCM, holiday) can multiply normal order volume for a few weeks. Rather than over-ordering for the whole quarter, place a standing order sized for your normal weeks and a smaller top-up order two to three weeks ahead of a known spike — well within our standard lead time.

Key takeawayOrder for your average month plus a 15–20% buffer, and place a seasonal top-up order two to three weeks ahead of a known rush.
