What does HTML email development cost?
Written by the studio that designs and codes these emails every week — with real examples from client programmes.
In the UK in 2026, a professionally designed and hand-coded email costs from £95, and a connected flow of 3–5 emails from £295, with fixed quotes standard. Agency retainers run higher; sub-£30 marketplace emails are typically untested template edits.
Short answer: at EmailDesign, a single custom email — designed, hand-coded and tested — starts from £95, and flow packages of 3–5 connected emails start from £295. Larger programmes get a fixed quote before any work starts. That's the honest baseline for professional, UK-based work in 2026.
What changes the price
Complexity is the main driver: dynamic product blocks, heavy interactivity, multiple language versions or very long editorial formats take longer to design and code. Platform setup — connecting flows in Klaviyo or building editor-compatible Mailchimp masters — is included in our packages, but adds cost when bought separately elsewhere.
What you should get for the money
- Custom design (not a reskinned template gallery file)
- Hand-coded, table-based HTML
- Testing across 60+ email clients including Outlook and dark mode
- Upload and setup in your email platform
- A fixed quote — hourly meters punish you for the vendor's inefficiency
Cheap vs affordable
£20 Fiverr emails exist. They're usually template edits with untested code that breaks in Outlook — which your B2B customers still use. Affordable means paying once for something that works everywhere. See our full service details or pricing page.
