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.
So far, so good! We did have an issue with internal addresses being blocked because we didn't have one of our send addresses whitelisted (to prevent malicious attacks).
