I hate it too, but the complications of personalised email really do
outweigh the benefits, unless you're prepared for:
a) long development time
b) constantly hitting the "ceiling" of your code/server limits and having to
re-evaluate the code ("it worked for 1000, but now i have 3000", etc)
c) placing HUGE burdens on the server
Bulk mail in a personalised manner should be done with dedicated software
and a dedicated server... I think it's a little wishful to place such
burdens on a WEB server... especially one which is a shared server.
Even if the code does work, the sysadmin should shut it down to prevent the
massive performance hit you cause.
If you've got your own server(s), that's a different story... but then I'd
be using ezmlm or something like that.

I guess you are putting 500 emails in the Bcc field. I guess. I like to personalize outgoing mail. I has a script sending *lots* of email and I didn't think it through. My cohort had to clean up after me and he said that he just changed a parameter to sendmail to queue the mail, I *think* ... I haven't sent a lot of mail since then but I'll look at how I was using sendmail.

Eeks. I hate that. I hate email that does not indicate it knows who I am. Why is sending one email to one user so bad? I can't think of a reason that would trump the personalization that I like so much. But I'm all ears.

I am not sure what you mean by 500 emails per header. Anyway, if you are personalizing messages, ie send a message per user, avoid that at all costs and if possible send a single message to all users. -- Regards, Manuel Lemos -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
