Our Approach
We start by getting a clear understanding of your brand, your audience, and your marketing goals - making sure every email template is built to align perfectly with your overall strategy. From there, we design layouts that make your emails easy to read, visually engaging, and packed with strong messaging and clear calls to action. Once the templates are ready, we integrate them seamlessly with HubSpot’s email automation tools, so your team can build and send campaigns without any technical headaches. Through ongoing testing and optimisation, we fine-tune every template to maximise deliverability, boost engagement, and drive stronger conversions.

Easy to start
Working with Openside Digital is easy and straightforward. We start with a quick consultation to understand your needs and review your existing email strategy. From there, we design a custom template that’s tailored to your brand - making sure it’s user-friendly, visually striking, and fully optimised for all devices. Once the design is locked in, we handle the integration, testing, and fine-tuning using HubSpot’s powerful tools, giving you everything you need to launch high-impact email campaigns with confidence, turning more of your audience into loyal, long-term customers.
Brand & Strategy Alignment
We start by understanding your brand identity, audience, and marketing goals. This helps us create email templates that reinforce your messaging, maintain visual consistency, and align with your broader marketing strategy. We also assess your current email performance to identify areas for improvement.
Custom Template Development
Our team designs professional, conversion-focused email templates that enhance readability and engagement. We ensure a strong content hierarchy, making key messages stand out while keeping the design clean and intuitive. Every template is built to be flexible, allowing for easy updates and customisation.
HubSpot Integration & Automation Readiness
We integrate your templates directly into HubSpot. This ensures efficiency and compatibility with personalisation tokens, CRM segmentation, and automated workflows so that your emails reach the right people at the right time with relevant content.
Deliverability & Performance Optimisation
A great email is only effective if it lands in the inbox. We optimise every template for fast load times, mobile responsiveness, and spam filter compliance. Your emails will look great across all devices and consistently reach your audience.
A/B Testing & Engagement Analysis
We test subject lines, CTAs, and design variations to determine what resonates most with your audience. We will then refine your templates to continuously improve engagement and performance from the stats we find.
Continuous Optimisation & Template Updates
Email marketing evolves, and your templates should too. We provide ongoing refinements, ensuring your emails remain fresh, effective, and aligned with the latest best practices.

Openside Digital's custom email templates make it easy for your business to create engaging, high-performing campaigns, without the hassle of starting from scratch. We focus on clarity, mobile responsiveness, and brand consistency, so every email you send builds stronger customer relationships and drives real, measurable results.
