Marketer from Email Geeks explains that there is no single correct answer for how much daily email you can send from one IP address. It depends on recipient mailbox distribution, the number of senders, content type (transactional or marketing), and reputation metrics. It also depends on your sending infrastructure. Although a single IP may handle 1-2 million messages per hour technically, other infrastructure considerations exist. He suggests nobody can give a single answer without knowing a lot more about your specific circumstances.

What the experts say4Expert opinions
Expert from Email Geeks responds to how much daily email you can send from one IP address. She says 1 - 2 million messages a day.
Expert from Word to the Wise, Laura Atkins, responds that there isn't a single number. It's important to gradually increase volume based on engagement and feedback. Start small (hundreds, not thousands) and watch your metrics.
Expert from Email Geeks shares that while some claim to send 8-10 million daily, the time period matters. Sending daily technically means within 24 hours, but delivery is desired in a smaller window. Overloading an ISP's inbound mail server is possible when pushing too hard. He suggests adding IPs proactively if approaching any limit.
Expert from Spam Resource, John Levine, explains that you need to warm up your IP address when you start sending email from it. The question isn't necessarily about a fixed number per day, but more about gradually increasing volume to establish a good reputation with ISPs.
