average return for every $1 spent on email marketing. Broken layouts throw part of that away.

Why templates matter
Email is a high-return channel. If it renders.
Every email client has its own rules. A template that breaks in one inbox quietly costs you clicks, sales and trust.
Built to survive every inbox
Designed for people. Coded for inboxes.
We design emails that are easy to scan on a phone, then hand-code them with the techniques email clients actually support.
- Mobile-first, responsive layouts. Single-column on phones, fluid on desktop, with buttons big enough to tap.
- Dark mode handled. Logos, colours and images checked so nothing disappears when the inbox goes dark.
- Accessible by default. Real text instead of image-only emails, alt text, readable sizes and good contrast.

We're a pharma company, not a tech company, so I needed someone who could take the website and the marketing side off my plate. RoundPatch rebuilt our site so it finally looks like the company we are, and they set up our email campaigns properly instead of the one-off mailers we used to send. They explain things in plain language, they reply quickly, and when I ask for a change it gets done.

Loaded into your platform, with a short guide for your team.
Which email platforms do you build for?
We build templates for HubSpot, Salesforce Marketing Cloud, Marketo, Mailchimp, Klaviyo, Braze, Iterable, MoEngage and most other platforms that accept custom HTML, with editable regions set up for your team.
Will our emails work in Outlook and dark mode?
Yes. We code with table-based, inline-styled HTML that Outlook supports and test every template in light and dark modes across major email clients before hand-over.
Can our team edit the templates without breaking them?
Yes. Templates are built as modular blocks with clearly defined editable areas, so your team can create new emails without touching the code.
Can you also run our email campaigns?
Yes. Beyond templates, we run email marketing end to end, from planning and segmentation to scheduling, reporting and analysis.
