Most email programs fail at the same point: they treat email subscriber lifecycle management as a list hygiene task rather than an operational discipline. The result shows up in suppressed open rates, creeping spam folder placement, and ISP throttling that nobody on the team can explain. By the time the numbers are bad enough to […]
