MarketingSherpa says "Yes" when it comes to email subject lines. They say emails with shorter subject lines are more likely to get opened. A somewhat contrarian position.

They’ve observed the presidential candidates’ email campaigns moving in this direction.
Something for e-fundraisers to test.

Yes, less is always better. e-fundraising letters with shorter subject are for sure,will be opened by the donor.
