Overall, this product works with STMP, Google and Outlook email accounts. It warms up as expected, and I haven't experienced hiccups as mentioned in the other reviews. However, I can't give this 5 tacos yet because I have yet to see an IPS score. I've been using this for a little over a week, so I'll update this as time goes on.

For now, I get AI generated email opens and replies. My gmail now is sending over 130 emails without any problems and it's warmed up! So time will tell as things go on how the other features work. I can tell you that the warming-up works!

Oh---and for STMP, it's great-- it does warm-up more than 120 emails a day to start with so that's great.

I saw a lot of negative feedback, and just wanted to make sure that I wrote a truthful review from my experience. hopefully this helps others. I think the price is worth it for lifetime -- it's just now waiting for the IPS to work.
