SendPost features: what you get on each plan
SendPost has no plans. There is no pricing page, no plan names and no free tier, and its own FAQ answers “Do you offer a free plan or trial?” with “No, at the moment we require a demo and up front financial commitment to use SendPost.” Every row below therefore carries no tier, and any SendPost price grid found elsewhere on the web is third-party invention. Sources checked 27 August 2026, the SendPost site, its documentation, its llms.txt index of 96 pages and its SendWorks product pages.

A feature page with nothing to gate
Every other platform in this directory earns its features tab by disagreeing with itself about which plan unlocks what. SendPost cannot, because it publishes no plans. The path to its pricing page serves the homepage instead, every call to action is “Schedule Demo” rather than “Sign up”, and the one statement about how money is charged is that “you don’t overpay for storing contacts and only get charged for the emails you actually send”. So the useful question is not what your tier buys, but what exists at all.
Two counts disagree across SendPost’s own pages, and both are the sort a comparison would copy without checking. The marketing page claims SDKs in “over 14+ programming languages”; the documentation index ships six quickstarts. The webhook lifecycle page documents nine event types; the endpoint that creates a webhook accepts thirteen. Both are worth knowing before sizing an integration on marketing numbers.
