We've tried a couple of different strategies over the years. We used to send to regular donors plus those giving non-regular gifts totalling more than £100. Now we send to everyone. We don't use soft credits at all.

It's useful for correcting errors and is helpful for people filling in tax returns, so that's why we bother.

It's also a useful thing to put out a message, such as, "do you want email receipts", or this year "do you want to give by direct debit?".
