When the talented team at GoHenry approached us to migrate their entire customer marketing operation from Salesforce Marketing Cloud to Customer.io, they had an ambitious goal – to complete the transformation in just 8 weeks while maintaining seamless communication with millions of families across the UK and US.
This wasn’t just about moving data from one platform to another. It was about reimagining their entire customer engagement strategy, building a robust multichannel communication system, and empowering their team to drive even greater results.
The timeline was tight. The stakes were high. And we were ready to deliver.

The Challenge
GoHenry was on a tight deadline for ESP migration; their customer data and communications were managed across multiple platforms, requiring seamless and rapid transfer of journeys and emails for the UK and US.
They needed all of this completed in just 8 weeks, a timeline that would give most agencies panic. But we saw it as an opportunity to showcase what’s possible when you have the right expertise, tools, and partnership.
WeDoCRM’s Solution
To address this urgent need, we utilised ClickUp for project management and migrated their email templates and customer journeys to Customer.io. Despite having existing email templates in Salesforce Marketing Cloud, we rebuilt new templates in Customer.io due to its distinct drag-and-drop interface. This transition included developing main templates for marketing and service emails from scratch.
Why we rebuilt rather than copied:
Customer.io’s interface offers fundamentally different – and more powerful – capabilities than Salesforce Marketing Cloud. Simply migrating old templates would have meant missing out on features that could dramatically improve GoHenry’s results. We wanted to set them up for success, not just replicate what they had before.
What this delivered:
Beautiful, high-performing email templates that looked stunning across every device and email client, with the flexibility to support GoHenry’s ambitious growth plans.
What We Did for GoHenry:
We successfully migrated GoHenry from Salesforce Marketing Cloud to Customer.io, delivering a comprehensive multi-channel communication platform.

Client Testimonial from GoHenry
”After initially helping us with a CRM migration to a new platform, we reached out to WeDoCRM again to support us with Maternity cover for our Head of CRM role. We wanted someone to work in-house, they sourced and vetted candidates in good time and have provided us with a level of cover that suits our needs.
