UK Postbox Make integrationAutomate UK Postbox with Make.

What if every letter scanned in UK Postbox could start a follow-up on its own? The UK Postbox Make integration gives you 2 triggers, both scheduled, and no actions. This guide is for people who read their post online and want Make to react to new scans. You will connect your account and build a first working scenario.

What you can automate

What does the UK Postbox Make integration do?

The UK Postbox Make integration lets new scans in your UK Postbox account start a scenario, which is the automation you build in Make as a chain of modules. UK Postbox brings the starting point, 2 triggers that look for new envelope scans and new content scans, and the rest of the chain comes from other apps or from Make's own tools.

Team heads-up on arriving post. Put Watch New Envelope Scans first and pass each new scan to a chat or email module of another app, so the right colleague knows a letter has landed before anyone opens the dashboard.

A register of opened mail. When the inside of a letter is scanned, Watch New Content Scans picks up that scan, and a spreadsheet module from another app can log it as one line per scan for your records.

Different paths for different scans. Either trigger can feed a filter or a router, Make tools that send each bundle (one item passing from module to module, here one scan) down a different path.

What the integration does not do: it has no action and no search module, so Make cannot request a scan, forward a letter or look up older post in UK Postbox. It also has no Make an API Call module. The official documentation is short and flags itself as AI-generated, so check the details in your own account. If you also weigh n8n, our n8n vs Make comparison sets out the criteria, and Make pricing explains how operations are counted.

Connect

How do you connect UK Postbox to Make?

  1. 01

    Add a UK Postbox module

    In a new scenario, click the + and search for UK Postbox, then pick one of the two watch modules. Under the connection field, click Create a connection. A connection is your UK Postbox account linked to Make once and reused by every module of the app.

  2. 02

    Name the connection

    Give the connection a name you will recognize later, such as the company mailbox it belongs to. This step is optional, but it helps as soon as you link more than one UK Postbox account to the same Make organization.

  3. 03

    Authorize and save

    Depending on what UK Postbox shows you, either approve Make on the UK Postbox page or paste the key the app gives you. Then click Save. The module can now read your account and the connection appears in the list for the second trigger too.

First scenario

Your first scenario with UK Postbox

GoalWhen a new envelope scan appears in UK Postbox, Make passes it to a module of another app, for example a message to your team.

  1. 01

    Create the scenario

    From the Scenarios page, create a new scenario and click the large + in the middle of the editor. This first slot is where the trigger goes, the module that starts every run.

  2. 02

    Add Watch New Envelope Scans

    Search for UK Postbox, pick Watch New Envelope Scans and choose the connection you created. Fill in whatever the module asks for; Make lists what it can read once the connection exists.

  3. 03

    Add the next module

    Click the + on the right of the trigger and add a module from another app, such as a chat or email tool. Map the data coming from the scan into its fields so the message carries the details you need.

  4. 04

    Test with Run once

    Click Run once. Make runs the scenario one time, and you can open each module to read the bundles it received. If nothing comes through, wait for a new scan in UK Postbox and test again.

  5. 05

    Schedule and switch on

    Open the clock on the first module to set the schedule, every 15 minutes by default for a new scenario, then switch the scenario on. Each run that finds a scan uses operations, the unit Make counts on your plan.

Triggers

What can start a UK Postbox scenario?

2 modules start a scenario when something happens in UK Postbox. A scheduled trigger is checked by Make on the scenario's schedule; an instant one is called by UK Postbox as soon as it happens.

UK Postbox1Watch New Content Scans

Watch New Content Scans

triggerIn the docs only

You get a scenario run for each new content scan, the scan of what is inside a letter, so the scanned letter can move on to other tools without you downloading anything by hand.

How it fires
Make checks the app on the scenario's schedule, so a new scan is picked up at the next check rather than the moment it appears.
When to use it
choose it when the content matters, for instance to file an opened invoice or log a letter from a tax office.
Watch out
the documentation gives no field list for this module, so run it once and read the bundle before you map anything.
UK Postbox2Watch New Envelope Scans

Watch New Envelope Scans

triggerIn the docs only

This one reacts earlier in the life of a letter: it starts your scenario when a new envelope scan shows up, so you hear about post once the outside of it is scanned, at the next scheduled check.

How it fires
Make checks the app on the scenario's schedule; on the Free plan the shortest gap between two checks is 15 minutes, and 1 minute on paid plans.
When to use it
pick it for alerts, so someone can decide whether a letter deserves to be opened and scanned.
Watch out
judging by the module names, an envelope scan shows only the outside, so a flow built on it should not expect the letter itself.

FAQ

UK Postbox and Make: common questions

01Is the UK Postbox Make integration free?
Yes, on the Make side. UK Postbox is a standard app, available from the Free plan. That plan allows 2 active scenarios, a minimum of 15 minutes between two scheduled runs, 5 minutes of execution per run, files up to 5 MB and 512 MB of data transfer. Paid plans (Core, Pro, Teams and Enterprise) lower the interval to 1 minute and count usage in credits per month. You still need your own UK Postbox subscription, which is billed by UK Postbox and not covered here.
02What do you need to connect UK Postbox to Make?
An active UK Postbox account is the only prerequisite the documentation names. From there, add either watch module, click Create a connection, optionally give it a name, approve Make or paste the key UK Postbox provides, and click Save. The same connection then serves both triggers. The documentation gives no dedicated connection steps for this app, so if the screen differs from the generic Make flow, follow what UK Postbox displays and check that your subscription is active.
03Does the UK Postbox trigger react in real time?
No. Both UK Postbox triggers are scheduled (the documentation does not describe them, so this type is read from their names): Make checks your account on the schedule of the scenario instead of being alerted the moment a scan exists. A new scenario checks every 15 minutes by default. On the Free plan 15 minutes is also the shortest interval, while paid plans go down to 1 minute. Each check that brings back a scan uses operations, so a shorter interval means faster alerts but a bigger share of your plan.
04What if the UK Postbox module you need is missing?
It depends on what you need. The app only offers two watch triggers, with no action, no search and no Make an API Call module, so Make cannot ask UK Postbox to open, forward or fetch older mail. Everything after the trigger has to come from another app or from Make tools such as filters and routers. If your process needs to act inside UK Postbox itself, the team can review the case with you and look for another route.
05Should you use Make or n8n for UK Postbox?
It depends on the tool you already run. On Make, UK Postbox brings two scheduled triggers that watch envelope scans and content scans, and the rest of the flow comes from other apps. Before choosing n8n, check whether it offers a UK Postbox node and which events that node covers, then compare on that basis rather than on habit. If your other automations already live in one of the two tools, keeping the mail flow there is usually the simpler decision to maintain.
