email - Will I have problems if i implement a newsletter using PHP $mail? -

-

i mean,

i'n long term, when have many accounts (10,000+), send them all?

or better find 3rd party open script this?

thanks!

as far know, if send lot of email @ same moment, can blacklisted mail hosters spammer. 1 solution heard delay , send 1 smaller batch every hour or so, honnestly don't think efficient ;)

using external partner useful, maybe try mail chimp, free limit of 2k users, guess it's worth giving try. if go on 2k can consider getting paying service or not !
