Don't worry too much about typos. I know clean, error-free copy is nicer than messy copy, but the odd typo here or there just doesn't matter.
There's even some evidence that in fundraising, typos improve response. Maybe some people become more attentive when they find a typo, with enough additional attention to push a few more of them over the line to action.
But here's where you should sweat bullets over typos: phone numbers, URLs, zip codes -- get one of those wrong, and you can sink a fundraising campaign faster than you can say "backslash."
So proof everything like a maniac. But when those odd little typos happen, don't beat yourself up. Or anyone else.
