What you can automate

What does the Lob Make integration let you automate?

The Lob Make integration links your Lob account to Make so that a scenario, the automation you build in Make, can ask Lob to mail something or check an address. Each step of that scenario is a module, one brick that does one job, and Lob brings 6 of them, all actions.

Clean addresses before anything goes out. Put Verify a US Address or Verify an International Address right after the step that collects the address, so the next module works with an address Lob has checked.

Turn an event into a letter. When a record reaches the right stage in the tool your team already uses, Send a Letter hands the job to Lob. Send a Postcard and Send a Self-Mailer cover the lighter formats for a campaign or a reminder.

Reach the rest of the Lob API. Make an API Call reuses the same connection to call any endpoint of the Lob API that the listed modules leave out.

Know the limits before you start. Lob has no trigger in Make, so a Lob scenario starts from a schedule or from another app. The official documentation also warns that it was generated with AI from Lob's own docs, so check anything critical with Lob. If you are new to the editor, the Make training walks through the basics, and the Make pricing page explains how operations are counted. Weighing another tool? Read n8n vs Make.

Connect

How do you connect your Lob account to Make?

  1. 01

    Add a Lob module

    Log in to Make, open your scenario and add any Lob module. In the module panel, click Create a connection. A connection is your Lob account linked to Make once, then reused by every Lob module.

  2. 02

    Name the connection

    The Connection name field is optional. A clear name still helps when you keep several Lob accounts, for example one for tests and one for live mailings, since every module will ask you to pick one.

  3. 03

    Paste your Lob API key

    In Lob, click the Settings tab at the bottom left of the menu, then the API Keys icon, and copy the key shown on screen. Paste it into Make, or follow the instructions Make displays, and save.

First scenario

Build your first scenario with Lob

GoalWhen a new address comes in from another app, Make checks it with Lob and then sends a letter to it.

  1. 01

    Create the scenario

    On the Scenarios page, create a new scenario and click the +. Pick the app where your addresses arrive as the first module, since Lob itself has no trigger.

  2. 02

    Add Verify a US Address

    Click the + to the right of the first module, search for Lob and choose Verify a US Address. Click Create a connection and map the address data from the first module.

  3. 03

    Chain Send a Letter

    Add Send a Letter after the check. Map the verified address from the previous module, so every bundle, one item passing from module to module, carries the address Lob just checked.

  4. 04

    Test with Run once

    Click Run once to run the scenario a single time. Then read the bundles each module received and make sure the address flowed through.

  5. 05

    Schedule and switch on

    Set the schedule on the first module, every 15 minutes by default, then switch the scenario on. Each module run on a bundle counts as one operation on your Make plan.

Modules

What the Lob modules do in Make

Lob gives you 6 modules. For each one: what it does for you, when to reach for it, and what to watch out for.

Lob1

Make an API Call

ActionIn the docs only

This module opens the whole Lob API to your scenario, with the connection you already set up. You call an endpoint yourself instead of waiting for a dedicated module.

When to use it
the Lob feature you need has no module of its own in the list below.
Watch out
you build the request yourself, so keep the Lob API reference open while you fill it.
Lob2

Send a Letter

ActionIn the docs only

Send a Letter gives Lob a letter job straight from your scenario, so a formal message goes out by post without anyone preparing it by hand.

When to use it
a contract is signed or a notice has to leave, and the recipient's address is already in the scenario.
Watch out
place an address check just before it, so a wrong address is caught before Lob gets the job.
Lob3

Send a Postcard

ActionIn the docs only

With Send a Postcard, a single event in another app turns into a postcard request at Lob, a light way to greet or remind a customer on paper.

When to use it
a welcome after a first order, or a thank you when a customer joins a program.
Watch out
test with Run once on your own address before you map a whole list of customers.
Lob4

Send a Self-Mailer

ActionIn the docs only

Pick Send a Self-Mailer when a postcard feels too small and a letter too formal: the module asks Lob to send a self-mailer to the address you map.

When to use it
a promotional piece triggered when a contact lands in a new segment of your CRM.
Watch out
every contact that reaches the module becomes one mailing, so filter the list upstream.
Lob5

Verify a US Address

ActionIn the docs only

Verify a US Address asks Lob to check an address in the United States and hands the result to the next module, so your mailing steps work on data you can trust.

When to use it
right after a web form or a CRM update, before any Send module.
Watch out
it covers US addresses only; route other countries to Verify an International Address.
Lob6

Verify an International Address

ActionIn the docs only

For customers outside the United States, Verify an International Address gets Lob to check the address and passes the answer along the scenario.

When to use it
your store ships abroad and you want each foreign address checked before a letter or postcard leaves.
Watch out
check the country earlier in the scenario so each address reaches the right verify module.

FAQ

Lob and Make: common questions

01Is the Lob Make integration free?
Yes, on the Make side. Lob is a standard app, so you can use it on the Free plan. That plan allows 2 active scenarios, a minimum of 15 minutes between 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) bring the interval down to 1 minute and remove the cap on active scenarios. Your Lob subscription is a separate matter: check the Lob pricing page for it.
02What do you need to connect Lob to Make?
You need an active Lob account and valid API keys. In Lob, open the Settings tab at the bottom left, click the API Keys icon and copy the key shown. In Make, add a Lob module, click Create a connection, give it a name if you like, and paste the key. The connection is then shared by every Lob module in your scenarios, so you only do this once per account.
03Can a Lob scenario start in real time?
Not from Lob itself: the app has no trigger in Make, only 6 action modules. You start the scenario another way. Either put a trigger from another app first, such as the form or CRM where addresses arrive, or let Make run it on its schedule, every 15 minutes by default. An instant trigger from that other app, one it fires through a webhook the moment something happens, is the way to react without waiting for the next scheduled run.
04What if the Lob module you need is missing in Make?
Use Make an API Call. It is part of the Lob app in Make and lets your scenario call any endpoint of the Lob API with the same connection, so you are not limited to the 5 other modules. Keep the Lob API reference at hand, because you write the request yourself. Also note that the official Make documentation for Lob says it was generated with AI, so confirm important details with Lob directly.
05Should you use Make or n8n for Lob?
It depends on the tool your team already builds in. In Make, Lob comes with 6 modules, including Make an API Call for the rest of the API, and it works on the Free plan. The same app often has a node in n8n as well, so check that before deciding. Compare the two on the modules your scenario needs and on where your other apps already live, rather than on reputation.
