A polite reminder

E-mails are part of our life for quite a long time and there's nothing more annoying than people not answering to you in e-mails. Of course, I'm talking about letters that are used in work purposes.

Have you ever heard such stupid excuses, when you call the company to ask, why are they ignoring your e-mail, and they simply lie to you - "We hadn't received anything" ?
You can hear such stuff everywhere in the world!

What a stupid excuse =)

Anyway, In this post, I wanted to discuss, how to send a reminder?
How do you guys do it?

As for me, I just forward the previous e-mail, adding only one word - "reminder" =)
I'm not sure that it's polite to remind about yourself in such a way. On the other hand, you will never look like a person who begs for the reply with some crappy phrases as "I am looking forward to hearing from you" and so on.

Rarely, I use a phrase "Please inform on the status of this request" as I normally send requests for quotation at work but the most straight and simple way to send a reminder - send this word only. isn't it? =)
