Consider whether you're comparatively advantaged to give to non-tax-deductible things.
(Not financial advice.) I think people -- especially donors who are giving >$100k/year -- often default to thinking that they should stick to tax-deductible giving, because they have an unusually high "501c3 multiplier" due to high marginal income tax rates or low cost basis for capital gains taxes. I claim this is a mistake for some donors, because what matters is whether your 501c3 multiplier is unusually high relative to the average dollar in the donor mix, which is usually coming from other people in very high tax brackets.
People who do have unusually high "501c3 multipliers" include those with employer matches to 501c3 donations. For a 1:1 match for cash donations, I think the multiplier is something like 3.5x, and even higher if you're donating appreciated assets like equity.[1]Â I would guess that you need to have a multiplier at least that good to actually be comparatively advantaged [ETA: because I think lots of the dollars from individual donors in the EA giving space come from people with 1:1 or better employer matches, like Google or Anthropic].[2]
The reason this matters is that if too many people think they're comparatively advantaged for tax-deductible giving, then non-tax-deductible opportunities (e.g. 501c4 advocacy, political giving, even future 501c3s awaiting their 501c3 determination) will unduly struggle to fundraise, so the best marginal opportunities are often going to be in that category.

If your donation budget is $10,000 (of post-tax income) and you're, say, a single San Franciscan making $500k (and therefore paying a 42.53% marginal tax rate, per SmartAsset), I think this means you could donate ~$17,400 in cash (a 1.74x multiplier) and deduct that from your income, reducing your tax burden by $7,400 = $10,000 from your post-tax income. Then your 1:1 employer match means the charity gets double that, or $34,800 (a 3.48x multiplier). If
