Mailing rules, postage rates, and holiday schedules change — sometimes every year. This page explains how BuyHolidayStamps.com keeps its content accurate over time: what gets reviewed, how often, and what happens when something turns out to be wrong.
Three Kinds of Content, Three Review Rhythms
Dynamic content — rechecked when official information changes
Pages that state postage prices, USPS service rules, size and weight requirements, or official mailing dates are checked whenever USPS publishes relevant changes — for example, a price change announcement or the annual holiday mailing news release. Accuracy takes priority over everything else for these pages, because readers act on them directly. You will find this material mainly in USPS Mailing Rules and Postage & Stamp Guides.
Annual content — reviewed every year
Seasonal pages, such as the 2026 Holiday Mailing Calendar and Christmas card timing guides, are written for a named year, reviewed as that year’s official USPS information is released, and kept online afterward as clearly dated historical references. A new year’s version does not silently overwrite the old one, and old pages are labeled with the year they cover so they are never mistaken for current advice.
Evergreen content — improved when it needs it
Guides such as addressing an envelope or writing a Christmas card change slowly. They are updated when accuracy, clarity, or reader questions show a gap — a missing exception, a better example, a clearer checklist — not merely to change a date or shuffle wording.
What Counts as a Meaningful Update
- Correcting a rate, rule, date, or instruction after checking it against the official source.
- Adding a genuinely useful section, example, checklist, or table that answers a question readers actually have.
- Reworking a page whose advice no longer matches current USPS practice.
- Improving internal links where they help readers reach the next relevant guide.
Cosmetic edits — changing a few words, refreshing a date without re-verifying the facts, or rearranging paragraphs to look “new” — are not treated as updates on this site.
Corrections
If you spot an error, email us through the Contact Us page and identify the page and the statement in question. Reports are verified against the official source listed on Sources & References; confirmed errors are corrected promptly, and the corrected page carries its normal update history. We do not quietly leave known errors in place.
When Information Is Not Yet Official
Some facts readers want — most often USPS’s recommended Christmas mailing dates — are announced on USPS’s schedule, not ours. Until USPS publishes them, pages say plainly that the dates have not been officially confirmed and offer clearly labeled planning recommendations instead. Once the official announcement appears, those pages are updated to reflect it. This approach follows our Editorial Policy.
