I have 1500 leads that I want to send emails to. I assumed that I could set up a 'schedule mass email' which would email 250 contacts each day until all 1500 had been sent an email.

I've just checked another post and this doesnt seem to be possible. In fact there does not seem to be any way of emailing the 1500 except for choosing blocks of 250 leads manually then emailing each block?!
