Where to donate?

I know there are a lot of political battles being fought, and I want to help. That said, I am:

1. Really, really, really tired of the unending texts, emails, and calls. Tired is putting it mildly, actually; I am furious. I find them annoying as hell, and I really want to help, but the unchecked text bullying is relentless. So, I don't want to give my contact info away if I just get harassed.
2. I am very skeptical of ActBlue, now. There are candidates I'd prefer get primaried, and it feels like ActBlue is such a dang machine that I'm "feeding the beast" instead of aiding in a progressive fight.

So, my questions are, where and how can I go to donate to candidates I genuinely support, without getting stuck in this b.s. innundation of contact spam?
