What you can automate

What can the Mailcheck Make integration do for you?

It lets Make send an email address to Mailcheck and get back a verdict on deliverability, with a Trust Rate and, when Mailcheck can find it, some data about the person behind the address. You do this inside a scenario, which is the automation you build in Make as a chain of modules, and no code is involved.

A cleaner signup list. Someone fills in a form, and before the contact reaches your CRM, Validate Single Email tells you whether the address looks deliverable. You keep the good ones and set the doubtful ones aside for a human to review.

Richer lead records. The same module can return enrichment data about the owner of the address when Mailcheck has it. A sales rep opening a new lead then sees more than a bare email.

Anything the listed module skips. Make an API Call reaches any endpoint of the Mailcheck API with the connection you already set up. It is the way out when your need goes beyond checking one address.

Be clear about what is missing: Mailcheck has no trigger in Make, so nothing starts on its own from Mailcheck. Your scenario begins with another app or with a schedule. The official doc also warns that its Mailcheck page is AI-generated from vendor material, so double-check anything critical with Mailcheck. If Make is new to you, the Make training covers the basics, and the n8n vs Make comparison helps if you are still choosing a tool. Mailcheck also has a node on the other side: see the Mailcheck n8n integration.

Connect

How do you connect Mailcheck to Make?

  1. 01

    Copy your API key

    Log in to Mailcheck, stay on the dashboard, and open the API tab at the top. The key shown on that page is what Make needs. You need an active Mailcheck account first; subscription details sit on the Mailcheck pricing page.

  2. 02

    Add a Mailcheck module

    In your Make scenario, add any Mailcheck module and click Create a connection. A connection is your Mailcheck account linked to Make once, then reused by both modules. Filling the Connection name field is optional, but a clear name helps later.

  3. 03

    Paste the key and save

    Paste the API key you copied, or follow the instructions Make shows on screen, then confirm. Done. Every Mailcheck module in any of your scenarios can now pick this connection from a list, with no need to paste the key again.

First scenario

Your first scenario with Mailcheck

GoalWhen a new contact lands in another app, Make checks its address with Validate Single Email.

  1. 01

    Create the scenario

    Open the Scenarios page, create a new scenario, and click the big + to place your first module. A module is one brick of the scenario: a trigger, an action or a search.

  2. 02

    Start with a new contact

    Mailcheck has no trigger, so the first module comes from the app where contacts arrive: your form tool, CRM or spreadsheet. Pick its new-contact trigger and connect that account.

  3. 03

    Add Validate Single Email

    Click the + on the right of the trigger, search for Mailcheck and choose Validate Single Email. Select your connection, then map the email address the trigger just received.

  4. 04

    Test with Run once

    Add a test contact, then click Run once. Make runs the scenario a single time and shows the bundle each module received: here, one contact and the verdict with its Trust Rate.

  5. 05

    Switch it on

    If the trigger is scheduled, its clock sets the pace: every 15 minutes by default for a new scenario. Switch the scenario on. Each module run on one contact counts as one operation on your plan.

Modules

What the Mailcheck modules do

Mailcheck gives you 2 modules. For each one: what it does for you, when to reach for it, and what to watch out for.

Mailcheck1

Make an API Call

Action

In Make“Performs an arbitrary authorized API call.”

This is your spare key to the whole Mailcheck API. It sends an authorized request to any endpoint, reusing the connection you already created, so no second login is needed.

When to use it
your process needs something Validate Single Email does not offer, and the Mailcheck API covers it.
Watch out
Make only knows the module, not the endpoints, so read the Mailcheck API documentation before you build the request.
Mailcheck2

Validate Single Email

Action

In Make“Retrieves data about email deliverability (Trust Rate) and enrichment data about email owner if possible.”

Hand it one address and it comes back with a deliverability verdict, including a Trust Rate, plus enrichment data about the owner when Mailcheck can find some. One address in, one answer out.

When to use it
a new contact arrives from a form or a spreadsheet, and you want to know if it is worth adding before it hits your list.
Watch out
enrichment is not guaranteed, so plan a route in your scenario for results that come back without it.

FAQ

Questions people ask next

01Is the Mailcheck Make integration free?
Yes on the Make side: Mailcheck 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 count usage in credits. Mailcheck itself is a separate account: you need an active one with an API key, and its own pricing page explains the subscription.
02What do you need to connect Mailcheck to Make?
An active Mailcheck account and its API key. Log in to Mailcheck, open the API tab at the top of the dashboard, and copy the key displayed there. In Make, add a Mailcheck module, click Create a connection, optionally name it, and paste the key. That single connection then serves both modules, Validate Single Email and Make an API Call, in every scenario you build afterward. Nothing else is required on the Make side.
03Can Mailcheck start a Make scenario in real time?
No. Mailcheck has no trigger module in Make, so it cannot start a scenario by itself. You have two ways around that. Put a trigger from another app first, such as a new form entry, and let Mailcheck check the address that comes through. Or run the scenario on a schedule from the clock on the first module; a new scenario runs every 15 minutes by default, and the Free plan cannot go below that interval.
04What if the Mailcheck module you need is missing?
Use Make an API Call. It can reach any endpoint of the Mailcheck API with the connection you already have, so you are not limited to Validate Single Email. You will need the Mailcheck API documentation to know which endpoint to call and what it expects. Also keep in mind that the official Make page for Mailcheck is flagged as AI-generated from vendor documentation, so confirm important details with Mailcheck directly.
05Should you use Make or n8n for Mailcheck?
It depends on where the rest of your automations already live. Mailcheck exists on both sides, and this page covers the Make version with its 2 modules. If your team already builds in n8n, the Mailcheck n8n integration page walks through that node instead. If you are choosing from scratch, the n8n vs Make comparison linked in the section above sets out the criteria. There is no need to switch tools just for one email check.
