SendGrid Migration in Swansea
Moving Swansea organisations' transactional email onto SendGrid or across to another provider. Sending reputation does not come with you — it belongs to the addresses and domain configuration you are leaving — so a full-volume switch on day one is the standard way to have important mail rejected.
Why this comes up
The problem
The email provider is changing on cost or reliability grounds, and password resets and order confirmations cannot afford a period of poor delivery.
What you get
What we deliver
- Authentication configured and verified at the destination before any live traffic
- Suppression lists exported and imported, so previously bounced addresses stay suppressed
- Volume increased gradually rather than switched entirely in one release
- Templates rebuilt and tested across the clients your recipients actually use
- Event handling reconnected, since webhook formats differ between providers
- Delivery compared during the transition, so a decline is caught immediately

Wales

SendGrid Migration in Swansea — common questions
- Can we switch all traffic at once?
- You can, and it is the common way to cause an incident. New sending infrastructure has no established reputation, and a sudden volume of mail from an unfamiliar source is treated with suspicion. Ramping over a week or two costs nothing and avoids it.
- Do suppression lists transfer?
- Not automatically, and they must. Addresses that hard bounced or complained need to arrive at the new provider still suppressed, or your first days of sending include repeated attempts to dead addresses — exactly the behaviour that establishes a poor reputation.
- What breaks in templates?
- Variable syntax and conditional logic, which differ between providers. A template that renders correctly in testing can fail on a specific recipient's data, so testing with real records rather than sample values is what catches the awkward cases.
- How do we know it is working?
- By comparing delivery rates during the ramp. Running both paths and watching bounce, complaint and open rates side by side shows a problem within hours. Switching entirely and waiting for complaints means learning about it from customers.
- Do you work with businesses across Swansea?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Swansea and the surrounding Swansea area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Swansea businesses do you usually work with?
- Bilingual public-facing systems for institutional clients, and seasonal booking for the Gower tourism trade. Beyond that we work across Higher Education, Healthcare, Manufacturing, Tourism and Public Sector.
- Do you cover the areas around Swansea?
- Yes — we work throughout Wales, including Cardiff, Newport. Swansea is an urban area of roughly 240,000+, and we take on work across the wider Swansea region rather than the city boundary alone.
