Email template
An email template is a reusable design framework for marketing emails that provides a consistent visual structure, into which content is inserted for each specific send. Templates typically include fixed design elements such as the header (with logo and brand colours), footer (with unsubscribe link, address, and compliance text), and overall column layout, alongside editable content zones where the specific text, images, and calls to action for each campaign are placed. This separation of structure and content means the structural design work is done once and reused across every campaign that uses that template.
Templates serve multiple purposes. They ensure visual consistency across all emails, reinforcing brand identity. They reduce production time by providing a ready-made framework that only requires content changes for each new send. They encode compliance requirements (like mandatory unsubscribe links) into the structure so they cannot be accidentally omitted. And they allow non-designers to produce professional-looking emails within guardrails that protect the brand.
For B2B marketing teams, a well-maintained template library is a significant operational asset. You might maintain different templates for different communication types: a newsletter template, a promotional email template, a plain-text-style sales email template, an event invitation template. Each is optimised for its use case. Building and maintaining these templates is an upfront investment that pays dividends with every campaign by reducing the time from brief to send.
What makes a good email template?
A good email template is visually consistent with your brand, renders correctly across all major email clients, loads quickly (with images hosted externally and HTML kept lean), includes all legally required elements (unsubscribe link, company address), is accessible (proper heading hierarchy, sufficient colour contrast, ALT text fields), is easy to use without technical knowledge, and is flexible enough to accommodate different content types without breaking the layout. The best templates are also tested regularly and updated as email client rendering changes.
Should I use a pre-built template or a custom-designed template?
Pre-built templates, available from your email platform’s template library, are the fastest way to get started and are fine for many use cases. Custom-designed templates are worth investing in when brand consistency is important, when your content types do not fit neatly into generic layouts, or when you are producing high volumes of email and want to optimise production efficiency. A hybrid approach, using a custom-designed master template that adapts to different layouts, often gives the best balance of brand control and flexibility.
How often should I update my email templates?
Review your templates at least once a year to check for rendering issues in new email client versions, test for accessibility compliance, and assess whether the design still reflects your current brand. Major trigger points for a template update include a brand refresh, a significant change in your product or marketing focus, changes to mandatory compliance elements, or evidence from testing that your current template is underperforming. Keeping templates current protects both deliverability and the recipient experience.
