What the experts say3Expert opinions
Expert from Spamresource.com explains that there isn't a hard maximum but outlines a detailed IP warm-up schedule. It recommends starting with a smaller volume (e.g., a few thousand) and gradually increasing the sending volume daily, based on engagement and ISP feedback. The specific number of emails to send depends on factors such as list size and the desired warm-up period.
Expert from Email Geeks shares that good practice can't be defined by a number. Even with the capability to send millions daily from a single address, spreading the volume out is beneficial for operations, redundancy, and deliverability headroom.
Expert from Word to the Wise (Laura Atkins) explains that it's not about the absolute maximum, but about maintaining a good sender reputation. Sending too much mail before you've established a good reputation can damage your deliverability. Volume should be scaled based on engagement and complaints.
