If your mail arrives after the moment has passed, it does not matter how strong the offer was. The response window shrinks, the follow up sequence loses alignment, and performance starts to look inconsistent across regions.
That is why entry point optimization matters. It is one of the most practical ways to reduce delivery variance and run campaigns you can actually plan around. You are not trying to control the USPS network. You are choosing how your mail enters it, and that choice affects how predictable your delivery window can be.
This guide breaks down what mail entry points are, how they influence timing, when each option tends to make sense, and how to build a simple entry strategy that supports better campaign execution.
Most teams treat mail like a single handoff: print it, drop it, and wait for delivery.
In reality, mail moves through a network of processing facilities before it reaches the local delivery unit that hands it to a carrier. Every additional handoff is another point where timing can vary. Entry point optimization reduces some of that variance by injecting mail closer to where it needs to go.
Instead of dropping everything near your print site or your office, you route mail to an entry facility that better matches your recipient geography.
The result you are aiming for is not “fastest possible delivery.” It is a more predictable delivery window so you can time the rest of your campaign with confidence.
USPS operates like a hub and spoke system. Mail can move from an origin processing center to a regional hub, then to a destination hub, and finally to a local delivery unit. The path is not always linear, and the number of stops depends on geography, mail class, and how volume is being processed that week.
A few factors that commonly introduce variance:
Entry point optimization does not remove these realities, but it can reduce unnecessary hops and make delivery behavior more consistent across regions.
Entry points describe where mail is inducted into USPS for processing. Different entry options can change how much of the network your mail needs to traverse before it reaches the destination area.
NDC entry is often used for broad geographic coverage. It is commonly a practical default when you are mailing across many regions and want a single operational approach for a national drop.

SCF entry can be a strong choice when your campaign is concentrated in specific regions. Entering closer to the destination region can reduce upstream handling and can improve predictability for regionally focused mailings.

What to watch:
Destination entry is not for every scenario, but it can make sense when your targeting is highly concentrated and your timing needs are strict. It is often more relevant when you are intentionally trying to reduce the last part of the network journey for a specific footprint.

Entry point optimization helps with predictability, but it does not override USPS service standards.
Marketing Mail follows service standards that can extend delivery windows compared to First Class Mail. If your campaign depends on tight timing, align three things early:
A common mistake is planning the follow ups as if all mail behaves like a short, fixed delivery timeline. That is how campaigns fall out of sync and reporting becomes hard to interpret.
If you want a quick way to choose an entry approach, start with the footprint of your list and the stakes of timing.
Default to a strategy that supports consistent execution across regions. Focus on predictability, then use delivery visibility to tune sequencing over time.
Consider entering closer to that region so delivery behavior is more consistent within your target footprint. This is where you can often tighten the delivery window and reduce multi wave delivery patterns.
Plan around a delivery window and build in flexibility. Use delivery signals to trigger or adjust follow ups rather than relying on a single calendar date.
Entry point strategy is most valuable when it prevents these common problems:
When timing is steadier, measurement is cleaner. It becomes easier to compare performance across audiences, offers, and markets without wondering whether delivery timing distorted the result.
Entry point optimization works best when you pair it with a campaign plan built around ranges, not a single delivery day.
Verify and standardize addresses before you send. Bad addresses create waste, increase undeliverables, and introduce noise into both timing and performance reporting.
Decide how long you will measure after expected delivery. A short window can undercount outcomes, especially for offers with longer consideration.
If you run email, paid social, or retargeting alongside mail, avoid hard scheduling based on a single predicted date. Instead:
Delivery visibility helps you run the campaign. Outcomes tell you if the campaign worked.
This separation prevents the team from confusing mail movement with campaign performance.
The best entry strategy is not always the same for every campaign. It changes with your list footprint, seasonality, and how narrow your timing window is.
If you are trying to tighten timing in one market, make sure you are not creating operational complexity that makes execution inconsistent elsewhere.
Mail is better planned in windows. You can still run a tight campaign. You just build sequencing that flexes based on delivery visibility rather than rigid calendar assumptions.
Stakeholders do not need a facility timeline. They need confidence that the campaign hit the market at the right time and produced measurable results.
Managing entry points manually gets complicated fast, especially if you run recurring campaigns, multiple regions, or multiple formats.
With Lob, you can automate direct mail and get delivery visibility so your team can coordinate timing across channels with more confidence. We help you reduce operational overhead by handling the logistics behind routing and tracking, while you focus on audience, offer, and creative.
When you can see when mail is moving and when it is reaching destination areas, you can time follow ups more intelligently, measure performance more cleanly, and run campaigns that feel coordinated instead of reactive.

FAQs about entry point optimization and direct mail timing
FAQs
What is an entry point in direct mail?
An entry point is the USPS facility where your mail is inducted into the postal network for processing and delivery. Your entry point affects how many facilities your mail passes through before it reaches the destination region, which can influence how predictable your delivery window is.
What is entry point optimization?
Entry point optimization is the practice of routing mail to the USPS facility that best matches your recipient geography instead of dropping everything at a single origin location. The goal is to reduce delivery variance and improve timing consistency so your campaign sequence stays aligned.
Which entry option is best for national campaigns?
For national campaigns, a broad entry strategy is often the most practical because it supports consistent execution across a wide footprint. The best choice depends on your list distribution, mail class, and how sensitive your campaign is to timing.
When does SCF entry make sense?
SCF entry can be a good fit when your recipients are concentrated in specific regions and you want more consistent delivery behavior within that footprint. It is often used for regionally targeted promotions, events, and campaigns where sequencing matters.
When does destination entry make sense?
Destination entry can make sense when your targeting is highly concentrated and your timing needs are strict. It is not a fit for every campaign, and it can add operational complexity depending on your footprint and logistics.
How does mail class affect delivery timing?
Mail class influences USPS service standards and delivery behavior. Marketing Mail can have a longer and more variable delivery window than First Class Mail. Entry point optimization can improve predictability, but it does not override service standards.
