Mailchimp Migration in Cardiff
Moving Cardiff organisations into or out of Mailchimp. Whichever direction, the list itself needs treating as the sensitive part — suppression records must travel intact, because a migration that loses them starts by emailing everyone who previously asked you to stop.
Why this comes up
The problem
The email platform is changing on cost or capability grounds, and years of list history, segmentation and templates have to survive the move.
What you get
What we deliver
- Suppression and unsubscribe lists migrated first and verified
- Audiences consolidated where several exist holding overlapping contacts
- Engagement history transferred so segmentation still works on arrival
- Consent records carried, including source and date for each contact
- Templates rebuilt, since these rarely transfer with formatting intact
- Sending authentication configured for the new platform before the first send

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Mailchimp Migration in Cardiff — common questions
- What must not be lost?
- Suppressions. Every address that unsubscribed, bounced or complained needs to arrive at the new platform still suppressed, and imports that bring only active subscribers quietly resurrect them. The first campaign then reaches people who opted out, which is both a complaint and a breach.
- Why does engagement history matter?
- Because your segments depend on it. Rules built around who opened recently or purchased in the last quarter produce nothing on a platform that received addresses with no history. Transferring engagement data is what lets targeting work from day one rather than after months of rebuilding.
- What about deliverability after the move?
- Expect a settling period. A new sending platform has no reputation for your domain, so authentication records must be configured correctly and volume increased gradually. Sending to the whole list on day one from a new platform is the reliable way to land in spam folders.
- Do templates transfer?
- Rarely intact. Email templates depend on platform-specific structure and merge tags, and exports typically produce something that needs rebuilding. Treating this as design work in the plan avoids a launch delayed by a template that looked fine until it was tested.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
