The choice between HTML and plain text should depend on your campaign goals and audience. Here are some scenarios:
- Promotional Campaigns: HTML is usually best for promotional emails due to its visual appeal and interactivity. - Transactional Emails: Plain text is often preferred for transactional emails such as order confirmations or account updates due to its simplicity and reliability. - Newsletters: HTML newsletters can be more engaging with sections, images, and links, although a plain text version can also be included for those who prefer it. - Personal Communications: Plain text is more suitable for personal or one-to-one emails, as it feels more genuine and less commercial.
