Narrow margins can cause several issues in email marketing:
1. Readability: Text that is too close to the edge can be hard to read, especially on mobile devices. This can lead to a poor user experience and higher unsubscribe rates. 2. Aesthetics: Narrow margins can make your email appear cluttered and unprofessional. A well-designed email should have a balanced look, which is hard to achieve with insufficient margins. 3. Accessibility: For subscribers who use screen readers or have visual impairments, narrow margins can make it difficult to navigate and understand the content.
