The verdict

The deciding factor is whether you need campaign software or just deliverability tools. Mailivery is the better fit for teams keeping their existing sending workflow and prioritizing warm-up, inbox placement tests, and blacklist monitoring in one plan. Smartlead is the better fit for teams that want warm-up alongside campaign sending, a unified inbox, and, on Pro and higher plans, a built-in CRM. Compare the relevant usage limits rather than the starting prices alone: the two products meter different activities.
