For those of you that mail out your invoices, how does your envelopes look. First of all, I think stamps are not professional, I may be wrong, but none of the bills I get in my mailbox have a stamp on them, they all have premetered postage on them, or a permit postage on them. I tried to inquire about that, and the local post office told me that I have to mail at least 200 pieces a month for qualify for anything beside a stamp For this next season I was thinking of using a double window evelopes with a much "professional" postage. I think it will improve the image of our company. How can you relate, how do you do it, and do you think its a big deal?
