IP Allocation and IP Warmup Schedule

It is important to note an IP warmup plan is merely a way to help the sender identify potential weaknesses in their email program. Starting slowly gives the sender a chance to pause or slow down sending and adjust their strategy before their reputation is severely impacted.
