Can emails have capital letters

Yes, emails can have capital letters. In fact, it's common to use capital letters at the beginning of sentences, proper nouns, and acronyms in emails.

Here are some examples of when you might use capital letters in an email:

1. At the beginning of a sentence: "I am going to the store today."
2. For proper nouns: "John Smith" or "New York City"
3. For acronyms: "NASA" or "HTML"
4. For titles: "Dr. Jane Doe" or "Mr. John Smith"
5. For emphasis: "I REALLY NEED THIS INFORMATION BY FRIDAY!"

However, it's worth noting that email clients and servers may not always preserve capital letters in the same way. For example:

• Some email clients may automatically convert all capital letters to lowercase.
• Some email servers may strip out excessive use of capital letters, such as all-caps text.
• Some email clients may not display capital letters correctly, especially if the email is sent in a non-standard format.

To ensure that your email is displayed correctly, it's a good idea to follow standard email formatting guidelines, such as:

• Using proper nouns and titles in title case (e.g. "John Smith" instead of "JOHN SMITH")
• Using sentence case for the rest of the email (e.g. "i am going to the store today" instead of "I AM GOING TO THE STORE TODAY")
• Avoiding excessive use of capital letters, such as all-caps text.

By following these guidelines, you can help ensure that your email is displayed correctly and is easy to read for the recipient.
