How many iMessages can you send per day?

There is no published hard cap. Each dedicated line carries a sensible daily sending capacity set to protect its deliverability, and the scaling move is adding lines rather than stuffing one line past its pace. Teams that push a single number to blast volume produce exactly the sending pattern that gets numbers flagged, on iMessage as on any channel.

The reason nobody serious publishes a magic number is that volume tolerance is not a constant. A line that holds two-way conversations, earns replies, and gets saved to contacts builds sender reputation that supports more volume; a line that fires one-way broadcasts at strangers degrades at a fraction of that pace. The daily number that is safe for one program is reckless for another.

The practical ceiling that matters is throughput across the account, and that scales linearly: one line per rep or per campaign, each pacing its own sends, each with its own reputation. Three lines is a common starting point for a small sales desk, per what a dedicated line includes.

Pacing is configured when a line is set up, matched to the program it will run, which is one of the things automation is for: a campaign tool that drips at a healthy pace all day beats a rep pasting a hundred messages in an hour, on results and on line health both.
