Electronic Mail Avoid All Caps SUMMARY: Please use mixed or all lower-case when sending e-mail.   While many people think writing a subject or electronic message in all capital letters makes their messages stand out from the rest, nowadays the opposite may occur. Many people look at such a practice as amateurish, and doing so may decrease the level of respect the intended recipient has for you. Others may consider using all capital letters the same as shouting, and such a practice is considered rude. Worse, some over-aggressive spam filters may tag messages or message subjects containing all capital letters as junk, meaning your messages may never reach their destinations.   Add: Del.icio.us | Digg | Furl | My Yahoo!   Discuss This Tip Print This Tip Get E-Mail When New Tips are Online Return to the Electronic Mail page.
