How can I email more than 100 people at once for an event w/o being spam filtered?

I am organizing my high school reunion and have email addresses for 120 members of our class. I want to send them announcements using BCC (as some members want to remain private) but I'm worried about ISPs confusing my message for spam. Any suggestions? One person recommends breaking the list up in chunks, but how many can be in a chunk before it gets filtered?

I've sent out a few mailers over the past year that had around the same number of recipients (family/friend updates and whatnot)... I just sent out in batches of only 10 to 15. I don't know what the limit is for an ISP, but when I did it this way I didn't seem to have a problem.





Also, I think you'll only really have to worry about people who are receiving the message at their work address. Those systems seem to be the ones that are more inclined to bump a message because of multiple recipients in the TO section of the message.





Good luck... I hope someone with better computer knowledge is able to help you out.

Please click the above link to know in detail. Happy emailing to u now.
Reply:Either you can set-up Read/receipt for all your out going emails from your account (but I am unsure if BCC read/receipt set-up can be done). This updates you who all have received your email %26amp; who haven't.


Secondly, you can request your classmate, in the email subject, to immediately confirm acknowledgment on receipt of this email.
