Email Deliverability Audit · Cardiff
Email Deliverability Audit in Cardiff
A deliverability audit for Cardiff organisations, covering the risk most businesses underestimate — that a poorly run marketing list damages the reputation of the domain sending your invoices. Order confirmations and password resets share a sender reputation with your newsletter, and mailbox providers judge all of it together.
Why this comes up
The problem
Campaign open rates have fallen quietly for months, and now customers say order confirmations are not arriving.
What you get
What we deliver
- Authentication verified end to end — sender policy, signing and the reporting policy
- Reports analysed to find every service sending on your behalf, including forgotten ones
- Transactional and marketing mail separated so one cannot damage the other
- Complaint and bounce rates measured against the thresholds providers now enforce
- List hygiene assessed, since inactive and invalid addresses drive most of the harm
- Unsubscribe handling checked, including the one-click requirement for bulk senders

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.

Email Deliverability Audit in Cardiff — common questions
- Why separate transactional and marketing mail?
- Because reputation attaches to the sending domain. A campaign generating complaints teaches mailbox providers to distrust everything from that source, and the first casualties are usually the password resets and receipts nobody thought were at risk.
- What do the reporting policies tell you?
- Who is sending as you. Reports reveal every service using your domain — the marketing platform, the helpdesk, the invoicing system, a supplier configured three years ago — and organisations are consistently surprised by two or three they had entirely forgotten.
- What thresholds are enforced now?
- Major providers publish requirements for bulk senders covering authentication, one-click unsubscribe and a spam complaint rate they expect you to stay well below. Exceeding the complaint threshold results in mail being rejected or filtered rather than a warning.
- Is list cleaning worth the lost subscribers?
- Almost always, and the arithmetic is straightforward. Addresses that have not opened anything in a year contribute nothing while depressing engagement and raising complaint rates, so removing them typically improves both delivery and results — a smaller list that arrives beats a larger one that is filtered.
- 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.
