How to review your mailroom process in December

How to Review Your Mailroom This December

December is the perfect moment to take a breath, look around your mailroom, and decide what you want to improve before next year’s busy season arrives. Many teams rush through year-end mailings without realizing how much smoother things could run with a quick audit. This guide walks through seven practical areas worth reviewing so your mail operations stay fast, accurate, and reliable in the year ahead.

Start With Your Address List

Before anything else, take inventory of your mailing data. Address lists tend to accumulate small errors over time, and those errors can lead to unnecessary returns or delays during heavy mailing months. December is a natural moment to check for duplicates, outdated entries, missing apartment numbers, and old addresses that need updating. A cleaner list means fewer surprises—and fewer stacks of returned envelopes waiting for attention in January.

Teams that send mail online through LetterStream often notice data issues earlier because the system makes inconsistencies easier to spot. A quick cleanup now can save hours of sorting and re-mailing next year.

Review Your Templates and Letter Formats

Your letter templates may be working, but are they still accurate, branded, and easy to read? Policies change, contact information gets updated, and branding evolves quietly in the background. Reviewing your templates now ensures that everything you send next year reflects the clear and professional tone your customers expect.

Clear subject lines, scannable text, and straightforward messaging also help recipients understand your letter the moment they open the envelope, reducing confusion and follow-up questions.

Clarify What Mail Is Truly Business-Critical

Not all mail carries the same weight. Some notices are time-sensitive and regulatory; others are informational or seasonal. December is a useful time to categorize what absolutely must be sent on a schedule and what can be adjusted, postponed, or moved online. Understanding these categories helps you allocate your team’s effort during peak periods and prevents everyone from scrambling at the same time.

Evaluate Internal Workflows and Bottlenecks

Most bottlenecks hide in plain sight. It may be a single person who handles approvals, a printer that only one or two team members can troubleshoot, or a handoff process that depends on everyone being physically in the office. These small friction points slow things down more than most teams realize.

Online mailing tools—like The Stream from LetterStream—can reveal these slow spots because they consolidate steps that normally involve multiple stages or people. When everything moves through one system, delays become easier to see and resolve.

Review Timing Patterns Throughout the Year

Think about when your mailroom felt busiest. Were certain months or billing cycles especially overwhelming? Did deadlines stack up at the same time every quarter? Understanding these patterns helps you shift preparation earlier, schedule support during peak weeks, or streamline certain notices before the pressure hits again.

Even small changes to timing can make your next busy season feel much more manageable.

Check That Your Records and Logs Are Up to Date

If your team logs returned mail, tracks outgoing volumes, or collects proof-of-mailing documents, December is an ideal time to confirm everything is current and accurate. Inconsistent documentation creates confusion later—especially when you need to reference a specific mailing or timeline.

When records are organized and current, you gain clearer insight into what’s working and what needs improvement next year.

Consider Whether It’s Time to Outsource Your Mailings

A year-end audit often raises an important question: Should we keep managing all of this in-house?


If your team spends valuable time printing, stuffing envelopes, fixing jams, or waiting on approvals, outsourcing some or all of your mail may free up significant hours.

Many organizations turn to LetterStream when they realize how much smoother operations become when they can print and send their mail online instead of relying on manual, on-premise processes. Outsourcing doesn’t replace your mailroom—it supports it by removing the repetitive, time-consuming steps so your team can focus on higher-value work.

A Strong Start Begins With a Thoughtful December

A quick year-end review can help your team catch small issues before they become bigger ones. By cleaning up data, refining templates, spotting bottlenecks, and deciding what truly needs to stay in-house, you set the stage for smoother, more efficient mail operations in the year ahead.
