8+ Tips: Should Marketing Email Subject Lines Be Capitalized?

The practice of using capitalization in marketing email subject lines refers to the strategic decision of whether or not to capitalize words within the subject line. Different capitalization approaches exist, ranging from sentence case (only the first word capitalized) to title case (major words capitalized) and all caps (every letter capitalized). For example, a subject line could read “New product launch this week!” (sentence case), “New Product Launch This Week!” (title case), or “NEW PRODUCT LAUNCH THIS WEEK!” (all caps).

Capitalization choices in this context influence open rates and perceived message tone. Historically, all caps was employed to denote urgency, but its overuse led to associations with spam. Current best practices generally lean towards sentence case or title case to project professionalism and readability. The selection depends on the brand voice, target audience, and the specific message conveyed.

9+ Email Subject Capitalization Tips: Should You?

The practice of capitalizing words in email subject lines refers to the application of capitalization rules to the text that introduces an email’s content. This can range from capitalizing only the first word to capitalizing all significant words within the phrase. As an example, consider the difference between “urgent meeting request” and “Urgent Meeting Request.” The former adheres to a more casual lowercase approach, while the latter employs title case capitalization.

Capitalization in subject lines can significantly affect how an email is perceived and processed by recipients. Historically, standardized business correspondence often favored capitalization in headings and titles to project formality and clarity. In the digital age, the perceived benefits extend to improved readability, emphasis of key information, and a potential increase in open rates. Furthermore, a well-capitalized subject line can reinforce a sense of professionalism and attention to detail, reflecting positively on the sender.
