For those of you on Wordfly and just had to deal with the IP migration - has it gone smoothly for you? We created our warm up plan, and WF signed off on it. We sent our first deployment on Monday (20K names or so) and it went out promptly, and had good open rates, and low bounces, but now we're seeing delayed sends and inconsistent delivery of tests emails. We'll open up a support ticket if it continues, but wanted to see if others were experiencing the same thing.
Are you looking at the domain break-out on the soft bounce page in the view results section (it's different than the page you get when you click on soft bounces)? Right now, my only problem child is Juno (and some .edu extensions). I sent my first block of around 11,000 addresses on Tuesday (top engagement scores), second block of around 15,000 yesterday and a third block of 24,000 today (the final chunk of around 30,000 goes out tomorrow). My send times have actually been faster than normal, but the responses have been really spread out, so they may not be landing all at once. My soft bounces have been 1% or lower.
