What realistic results can I expect from my first cold email campaign, and what volume is needed to start making money?
There are nine key variables—deliverability, open rate, reply rate, positive replies, meeting attendance, proposal conversion, sign‑up rate, refund rate, and your price—so you can’t give a single volume number. You need to estimate based on your own metrics; if you could send a million emails a day you’d likely make money, but you’d have to pay for that sending capacity.
