Using Sentence Case in Email Subject Lines
In every email, it is important to have a subject line that is easy to read and understand. Capitalizing your email subject lines in sentence case makes them easier to read since the words are easier to distinguish.
Hence, capitalizing every word on your subject is really not a good practice. Some people think that subject lines are like titles where most of the content words should be capitalized. Remember, this is not an essay. Treat your subject line as if it is the first sentence of your email. Take a look at the example below.
Good: This is a good subject line
Bad: This Is A Bad Subject Line
Like any other sentence, you should capitalize the first word of your subject line. Keep in mind that proper nouns should also be capitalized. It’s a universal convention and emails are no exception to this rule.
Why is capitalizing your subject line like a sentence important? The reason is very simple. By doing so, you appear more casual and approachable towards the person you are sending the email to. In addition to this, the style is easiest to remember since you only have to capitalize the first letter. You won’t need to be reviewing your capitalization rules time and again.
Using Title Case in Email Subject Lines
As we have mentioned before, using sentence case in email subjects is a good practice since it sounds more casual. But there are some situations which call for using title case in subject lines. The use of title case is a less common email subject capitalization technique, but it works in many subject lines especially in the business world since it looks more professional.
To be able to use the title case correctly, you must capitalize the following words in accordance with the APA, MLA, or Chicago style:
Aside from the words we have enumerated above, you should also capitalize the first word and any word that is more than three letters wrong.
If these rules are too complicated to remember, you can always use a free title capitalization tool like ours.
The use of title case would make your subject lines more formal and polished. However, you should make sure that your subject line is not too long or else it would be too overwhelming.
Avoid Using All Caps

This is indeed a wrong option, and we do not recommend that you do so. It is a risky move because using all caps in your subject lines will trigger spam filters. Capitalizing even just a word in your subject line could increase the chance that your email would be sent straight to the spam bin.
