If you depend on catalogs, publications, or large-volume direct mail, the rapid rise in postage costs can feel like a tightening vise. Budgets are harder to predict, mailing schedules are less forgiving, and every small inefficiency shows up in your bottom line.
At Integra Print & Promo, we work with several organizations navigating these exact pressures. One question keeps coming up: Is there a smart way to reduce postage costs without adding days to delivery?
Co-mailing is often the answer. In this guide, you’ll learn what co-mailing is, how it works, when it’s a fit, and how much you can realistically save—so you can make an informed, numbers-driven mailing decision.
Co-mailing is a process that combines multiple catalog or magazine titles into one larger, more efficient mail stream.
By pooling mailings, the combined volume qualifies for deeper USPS presort and automation discounts—savings most organizations can’t unlock on their own.
In plain English: Co-mailing gets your mail deeper into the USPS system at a lower cost—without slowing your delivery.
Co-mailing is straightforward, but it relies on coordination and volume. Here’s the simplified breakdown.
Regular mail pools keep schedules predictable
Most co-mail pools run twice per week, making it easy for catalogers and publishers to align production schedules without disrupting campaigns.
The larger the pool, the bigger the savings
More combined volume means more pieces qualify for the highest USPS discount tiers.
Your only incremental cost is inbound freight
Your mail must be delivered to the co-mail facility.
