Ryan, Usually I would recommend a ramp up of 10% of a list your size to start, increasing by another 10% every 3-5 days for a period of a month, if you run into issue hold at your current volume for a few more days. Ensure you have a normal mix of ISPs on the new traffic so your not appearing to be gaming the systems at a specific ISP.
Also in advance of changing IPs add the new IP ranges to your authentication records... at least 5-7 days in advance (when possible). At some ISPs there is a small but tangible reputation association for your records that new IPs will be associated with - especially if you have a good email reputation - that helps accelerate ramp ups then planned in advance. Also contacting them, again when possible in advance, could gain you some additional benefits... but with each ISP YMMV. ~ Matt On Sun, Oct 23, 2016 at 12:19 PM, ryan prihoda <ryanprih...@gmail.com> wrote: > Update: we seem to be ok with yahoo now and I have been in contact with > others off list.
