I'm a novice and still learning about email. I'm not too clear about dynamic IPs. For ESPs like gmail that only assign dynamic IPs to their customers, do they run into more risk of getting blocked. Since majority of the users use such kind of free ESPs and using mostly dynamic IPs, how is this fact taken into consideration by ISPs/ESPs when they look into blocking it?
