Install from AppExchange.
MCT is distributed as a Salesforce-security-reviewed managed package. Under 24 hours from install to first multilingual send.
What you'll need before you install.
Five clicks from AppExchange to sending.
- 01
Install the MCT package
Deploy the MCT installed package into your Marketing Cloud org. The block appears in Content Builder.
- 02
Create the API integration
Provision an installed package in Setup with Saved Content read + write. MCT uses least-privilege OAuth 2.0 client-credentials.
- 03
Deploy the MCT backend
Ship the backend to Azure App Service (default), SFMC CloudPages using SSJS, or a PHP host. Store client secrets in your managed secret store.
- 04
Configure the block
Open the MCT block in Content Builder, add do-not-translate terms, and set a naming prefix for generated blocks.
- 05
Compile your first switch email
Pick languages, translate & preview in-browser, then compile. Marketing Cloud sends the single IF/ELSE email.
Four components. Nothing more.
Drag-in block built on the Salesforce Block SDK using Postmonger for the Content Builder handshake.
One block per language, named with your prefix (prefix__es, prefix__fr, ...). Editable in Content Builder like any other block.
A single email with an AMPscript IF/ELSE that resolves the recipient's language via ContentBlockById.
Node.js backend (or SSJS / PHP variant) that runs recursive assembly, AMPscript stashing, Google Translate v2 calls, and SFMC REST writes.
Five checks and you're live.
Reviewed by Salesforce. Runs in your tenant.
The managed package passed Salesforce's security review. No data leaves your Marketing Cloud org unnecessarily, translations cache in your own Data Extensions.
