Published pricing in this category is rarely the price. Credits expire, exports carry overage rates, seats multiply, and the advertised monthly figure often assumes an annual commitment.
Each guide below takes one platform and answers the same questions: what the unit is, what happens when you exceed it, what the annual and monthly gap looks like, and which costs sit outside the headline plan.
One structural note that applies across all of them: a database subscription, a verification credit balance and a sending seat are three invoices for one workflow, and the comparison only means something when both sides are priced whole.
