Gundir365™ Postage Promise: Lock in your direct mail postage rate for a year 

The Gundir365™ Postage Promise locks in your direct mail postage rate for a full year and automatically credits you for the difference if USPS rates rise, up to your annual cap.

Your forever stamp for direct mail. 

The USPS raised postage rates again on July 12, 2026 — another reminder that postage costs are only headed in one direction over time. But at Gundir, we have a solution for that. Starting July 13, 2026, every qualifying Gundir client’s postage rate is locked in at around $0.40 per piece for a full year starting with any mailing after the promotion start date regardless of USPS rate changes. 

 Key takeaways: 

• Your postage rate locks in at approximately $0.40 per piece for 365 days — no mid-year surprises to your budget.
• Gundir automatically credits for USPS rate increases during your window, up to an annual cap — no claims, no paperwork.
• Monthly mailers can recoup up to $100,000 a year; quarterly mailers, up to $30,000, based on volume.

Why we built the Gundir365™ Postage Promise 

We’ve seen how postage increase uncertainty can derail budgets and direct mail campaign planning.

When the USPS raises rates, marketers are often faced with cutting volume, delaying drops, or pausing programs. Our new program is built for consistent mailers who need to manage campaign costs as a key aspect of channel optimization.

The Gundir365™ Postage Promise adds predictability and cost savings to the most expensive part of direct mail campaigns. Because Gundir is taking on the risk of any future postage increases for an entire year, our clients can budget a year’s worth of mailings with confidence. Now forecasts, ROI analyses, and proformas made on day 1 can stay intact through day 365.

“We’re invested in our clients’ success, and this unique program was built to take away the pain of rising postage costs.”

How the Gundir365™ Postage Promise works 

The program runs in three simple steps, and no paperwork is required to receive your credit. 

1. Lock in your rate 

Gundir clients get a locked-in postage rate at around $0.40 per piece starting with their first mailing after July 13, 2026 — for their full 365-day (1 year) window, regardless of USPS rate increases. 

2. Mail with confidence 

Mail monthly or quarterly knowing your postage cost is fixed. Build campaigns, set budgets, and forecast accurately all year long.

3. Receive your credit 

If the USPS raises rates during your window, Gundir provides a credit for the difference automatically at the end of the year, up to an annual cap based on volume and mailing frequency. No claims, no paperwork.

Savings structure 

Your annual credit scales with how much and how often you mail. The chart below shows the potential savings and caps for a variety of mail cadences and quantities:

Gundir provides a credit for the difference up to your annual cap; any amount above the cap is absorbed by the client.

When this applies / who it’s for 

If you’re already a regular mailer with Gundir, you’re automatically covered. There’s nothing to sign, nothing to track. And if you’re not yet a Gundir client but you’ve been considering the idea, this is a reason to start. 

Marketers looking for predictable, defensible numbers for direct mail budget planning will benefit from our postage promise:

• Current Gundir clients mailing with us through GundirLead, GundirLift, or GundirLaunch.
• Marketers who mail monthly or quarterly and manage an annual postage budget.
• New mailers who want cost certainty and budget stability before they commit to the channel.

Why partner with Gundir 

Gundir has spent years building long-lasting relationships with some of the country’s largest mailers, helping them lower customer acquisition costs and grow profits through address-based, integrated direct marketing programs. The Gundir365™ Postage Promise is an added benefit for when postage rates go up.

The reality is that postage rates will continue to climb. But, we’re changing who absorbs that risk. So the next time rates rise, it won’t mean re-working your program. It’ll be business as usual.
