Re: Sending lots of emails - 2 choices - choose the best one

The other possible question you might want to ask is: How will the message be formatted and sent... some services such as hotmail will flag the message as spam based on the multiple mail deliveries when used option #2. And there are also many other considerations related to spam. Instead what you could consider doing: Option #3) Write a subroutine that would group recipients based on host, and send one mail to each host with bcc. Also I would not use the internal mail function, instead I would try a full smtp class, especially when using mime that has built in support for services such as hotmail, yahoo, etc. Whenever we send email list to hotmail users I format the message differently then when we send to yahoo, and so on .... I would avoid allowing sendmail to handle the function of grouping ... Hope it helps... Marek Philip Thompson wrote:

Hello--

I want to send email to 100+ recipients. Two choices I thought of: 1) once call mail() and use BCC, but the negative of this method is that every recipient in BCC has header "To" same (so I used to put my email in here - not email of one of the recipients). 2) several calls to mail() function with each recipient's emal

Why are you sending mail to 100+ recipients? Is it something you do often? Is it always the same recipients? When are you sending them? If it's a mailing list use mailing list software as Daevid suggested - it's what it's for! I would recommend avoiding the use of BCC from PHP. -Stut

Why avoid Bcc from PHP? ~Philip
