Definition
Email brand voice is the consistent personality, style, and values expressed through the words used in email communication. It is how your brand sounds to subscribers — formal or casual, serious or playful, technical or accessible.
A well-defined brand voice makes your emails recognisable in a crowded inbox. Subscribers develop familiarity with and trust in a consistent voice. An inconsistent voice confuses subscribers and weakens the brand.
