Making your email searchable by including relevant keywords in the subject line or body can help recipients find emails more easily, especially for online sales and confirmations. This practice is particularly useful when sending transactional emails that may need to be referenced later, such as flight confirmations or account information. Including clear labels like sender name or product names can also improve searchability, making it easier for recipients to locate specific emails in their inbox. By optimizing email content with relevant keywords and labels, businesses can enhance the user experience and reduce the likelihood of emails being lost or forgotten.
