IP Warmup 

What does IP Warmup Mean?

IP Warmup – Sending a progressively increasing number of emails out of an IP address in order to build the IP’s reputation.

At the point when an ISP notices email abruptly coming from another or “cold” IP address, they will pay heed and promptly start assessing the traffic coming from that IP. Since ISPs treat email volume as a key deciding element when distinguishing spam, it is ideal to start sending a low to direct volume, ultimately moving gradually up to bigger volumes.
