Essential tool for sending any volume…
Essential tool for sending any volume of emails. Very easy to use. When I've talked with email consultants they nod approvingly when I say we use ZB. We've tried 1 or 2 other services bundled in with other tools but didn't get the detail or the results ZB provides.
That said: if you're sending to B2B addresses you're more likely to get "catch-all" which basically means it's an unknown. (That's just how email works) We don't find all of the additional insight/data offered that helpful but hopefully that evolves. Support is fine, sometimes feels like one of us has misunderstood but we get there soon enough and they are responsive.
