I have a very simple question. I am building a social networking website for people in the same profession as myself (Medical researcher). I want to send email notifications about threads posted on my site or other followed members activity. I'm coding the email functionality but I have to say, (i'm using PHPMailer), although my site may only have a max of 10-20k members in total, even sending off a few hundred emails in pretty slow. When does one move on to using a third party (if at all) like sendgrid? What experience do people have with this type of service dropped into their site?

Who reads e-mail in 2014? Really? Do you? Let's play with the thought that notifications can be made through other available services than an old SMTP-server. Did I hear you say App?
