"Evangelical" actually means something quite different from "evangelizing". The "evangel" is the "eu-angel", the "good news", the "gospel". Or, more specifically, the gospels, the first four books of the New Testament. To evangelize, to be "evangelistic", is to attempt to bring the "good news" to others. It's a matter of what you do. To be "evangelical" is (so at least members of the groups that go by that name would say) to be grounded in the "good news", the gospels, the New Testament. (As opposed to, say, later church traditions.) It's a matter of what you believe and where those beliefs (purport to) come from. The term "evangelical" has a complicated history, going back to Martin Luther and beyond. It's pretty much always denoted a strain of Protestantism, and in the modern-day US it means roughly "fundamentalist but not too fundamentalist". (On the other hand, in non-anglophone parts of Europe it mostly just means "Protestant".) Evangelicals tend to be evangelistic, not least because the New Testament tells them to be. But you can be evangelistic without being evangelical; as you say, that would describe any church that tries to expand its membership, or any individual Christian who tries to persuade others to convert.
