I have a list of about 100-150 or so e-mail addresses for customers that filled out "Request Information" cards at our booth at a recent trade show...so to be clear, I am not spamming in any form or fashion. Every address I am sending to was given to us by the address owner themselves for the sole purpose of us e-mailing them.

What I am looking for is the best method to get a pre-call e-mail to them to let them know we will be calling and to please visit our website to get an idea of what type pf product you might be interesting in yada yada yada.

I know I could just BCC the entire list in Outlook but I am afraid that mail servers will reject it or flag it as spam if I do that...and I certainly do not want to send out individual mails if it can be avoided.

Do any of you guys know of a Windows app (or a *nix script) that can accomplish this? Any tips you guys could provide would be greatly appreciated

A very nice and professional Windows app is GroupMail from www.infacta.com

But with only 150 recpients you should be fine with your BCC method...

You don't think having that many recipiants would flag spam software? I guess I could just do it in lots of 15-25 or so...that wouldn't be so bad.

That would be my suggestion. You also probably want to put language in the mail that says something to the effect of:

You have received this mail because you filled out a response card on this day, at this booth, in this trade show.

You're going to get complaints no matter what (those who refuse to behave themselves have broken email has a sales tool for the people trying to do it honestly), but at least you can dampen it down by the obvious, "you gave me your email address, so it's fair" disclaimer.

Outlook will work for this. I recommend you do 2 things.

1. Don't hide your email address. Make the return email address one that is checked.

2. If someone requests they no longer recieve any more emails from you, cross them off the list and only one more email that says you were removed from the list per your request and thank you for your business (something like that)

All very good points. Thanks for the advice guys
