PostGrid Make integrationAutomate PostGrid with Make.

Can a record in another tool turn into a letter or postcard without anyone touching it? The PostGrid Make integration gives you 5 action modules: three that send mail and two that verify addresses. This guide shows how to link your account and build a first scenario around them.

What you can automate

What can the PostGrid Make integration do for you?

The PostGrid Make integration lets a Make scenario, the automation you build in Make, ask PostGrid to send a letter, a postcard or a self-mailer, or to check a postal address. Each of these jobs is a module, one brick of the scenario, and you chain them without writing code.

Clean addresses before anything leaves. A contact lands in your CRM or a form tool, and Verify a US or Canada Address checks it first. Addresses from other countries go through Verify an International Address instead, so the verdict comes back before you spend anything on mail.

Mail that follows an event. A signed contract, a closed deal, an overdue invoice: the other app fires the scenario and Send a Letter handles the envelope. For a lighter touch, such as a thank you after a first order, Send a Postcard or Send a Self-Mailer fits better.

What the integration does not do. PostGrid has no trigger in Make, so something else has to start the scenario: another app or the Make schedule. It also has no universal API call module, so you work with these 5 modules only. The official PostGrid documentation on Make is flagged as AI-generated, so check important details with PostGrid.

Connect

How do you connect PostGrid to Make?

  1. 01

    Copy your PostGrid API key

    Log in to your PostGrid dashboard and open the Settings page. Your key sits under the API credentials; copy it. You need an active PostGrid account for this step, so create one first if needed.

  2. 02

    Open the connection window

    In your Make scenario, add any PostGrid module and click Create a connection. A connection is your PostGrid account linked to Make once, then reused by every PostGrid module you add later.

  3. 03

    Paste the key and save

    Give the connection a name in Connection name if you like (it is optional, but helps when you run several accounts), paste the API key you copied, and save. The module can now talk to PostGrid.

First scenario

Your first scenario with PostGrid

GoalWhen a new customer appears in another app, Make checks the address with PostGrid and sends a welcome letter.

  1. 01

    Create the scenario

    From the Scenarios page, create a new scenario and click the + to add the first module. Pick the app where your new customers show up, for example your CRM, and its trigger.

  2. 02

    Verify the address

    Click the + on the right to add Verify a US or Canada Address. Click Create a connection, paste your API key, then map the address from the first module.

  3. 03

    Send the letter

    Add Send a Letter with the + and map the recipient data from the previous modules. Each item passing through is a bundle: one customer, one letter.

  4. 04

    Test with Run once

    Click Run once to execute the scenario one time, then read the bundles each module received. Use your own address for the test, since the letter module acts for real.

  5. 05

    Schedule and switch it on

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

Modules

What the PostGrid modules do

PostGrid gives you 5 modules. For each one: what it does for you, when to reach for it, and what to watch out for.

PostGrid1

Send a Letter

ActionIn the docs only

This action hands PostGrid a letter to send, so a formal message reaches a mailbox without anyone printing or stamping it. Make feeds it the recipient data mapped from earlier modules.

When to use it
a document that needs an envelope, like a contract notice or a payment reminder triggered by your billing tool.
Watch out
Run once executes it for real, so point your test at your own address.
PostGrid2

Send a Postcard

ActionIn the docs only

Choose this module when a short, visual message does the job better than a sealed letter. It asks PostGrid to send a postcard to the contact passed along by the previous module.

When to use it
a thank you after a first purchase, or a reminder that an event is coming up.
Watch out
place a verify module before it, so an incomplete address is caught before the card goes out.
PostGrid3

Send a Self-Mailer

ActionIn the docs only

With Send a Self-Mailer, your scenario orders the third mail format of the integration, next to letters and postcards, and PostGrid takes care of sending it to the mapped contact.

When to use it
you need more room than a postcard offers, but not the formality of a letter, for instance a product announcement to recent buyers.
Watch out
the Make documentation describes no format for it, so check the options in PostGrid first.
PostGrid4

Verify a US or Canada Address

ActionIn the docs only

Before any mail leaves, this module checks an address located in the United States or Canada with PostGrid and returns the result to the next module. You avoid sending to a street that does not exist.

When to use it
right after a form or CRM trigger, when your customers are North American.
Watch out
an address outside those two countries belongs in the international module instead.
PostGrid5

Verify an International Address

ActionIn the docs only

Your contacts live abroad? This module sends the address to PostGrid for checking when it sits outside the United States and Canada, and passes the verdict on so you can decide what happens next.

When to use it
an online shop that ships to several countries and wants clean data before mailing anything.
Watch out
route addresses by country first, then send each one to the matching verify module.

FAQ

Questions about PostGrid and Make

01Is the PostGrid Make integration free?
Yes on the Make side: PostGrid is a standard app, available from 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, Enterprise) drop the interval to 1 minute and remove the limit on active scenarios. Make counts usage in operations, one per module run on a bundle. PostGrid itself needs an active account with its own subscription; see the PostGrid pricing page for that part.
02What does PostGrid need to connect to Make?
It takes an active PostGrid account and its API key. Log in to the PostGrid dashboard, open Settings and copy the key shown under the API credentials. Then, in Make, add a PostGrid module, click Create a connection, give it a name if you want, and paste the key. That one connection serves all five modules, so you only do this once per PostGrid account. If the connection is refused, copy the key again from Settings, because a key pasted with a missing character will not work.
03Does PostGrid trigger Make scenarios in real time?
No, because PostGrid has no trigger module in Make: all five modules are actions. Something else starts the scenario. The first option is a trigger from another app, such as a CRM or a form tool, placed before the PostGrid modules. The second is the Make schedule, set on the first module, which runs every 15 minutes by default. On the Free plan the minimum interval is 15 minutes, and paid plans go down to 1 minute. Either way, PostGrid only acts once the scenario reaches its module.
04What if a PostGrid module is missing in Make?
It depends on what you need. The integration covers five actions: sending letters, postcards and self-mailers, and verifying addresses in the US and Canada or elsewhere. Unlike some apps, PostGrid has no Make an API Call module in Make, so you cannot reach other features from the same connection. The official documentation is also marked as AI-generated and may contain mistakes, so confirm key details with PostGrid. If a need falls outside the five modules, another app or the Make agency team can help design an alternative scenario.
05Should you use Make or n8n for PostGrid?
It depends on criteria rather than on a winner. In Make, PostGrid offers five ready modules, runs from the Free plan and connects with a single API key, which suits someone building visually for the first time. Many apps also have an n8n node, so check whether PostGrid does and which operations it covers before choosing. Compare the modules you actually need, the way each tool counts usage and the one your team already knows. The n8n vs Make comparison linked in this guide sets out those criteria side by side.
