The iMessage platform category hides its prices: most vendors publish no usable number, so every pricing post here does the digging once, with each figure dated and sourced from the vendor's own site. Alongside the per-vendor pricing breakdowns sit the buying guides: what separates managed platforms from raw APIs, which criteria actually predict a good fit, and the safety questions worth asking before a contract. We sell in this category and say so on every page; the dates and sources are there so nothing has to be taken on faith.

Buyers compare the monthly price of a line and then build the campaign. The constraint that stops the campaign is somewhere else: a new-conversations-per-day figure buried in a comparison table, and an acceptable use policy that names cold outreach as prohibited on every plan. Both are published. Neither is on the page you compared.
