A great subject line can be the difference between catching the recipient’s attention to open your email or to be unceremoniously tossed into the trash or simply ignored. What makes a subject line stand out?

It needs to be concise. The best subject lines are between 3 and 6 words in length. You don’t have to explain the entire email in the subject line, it’s there to grab the recipient’s attention and motivate him to open the email.

The best nonprofit email appeal subject lines needs to be catchy. It isn’t enough to simply re-state what is in the email, but instead it needs to capture the recipients attention as he scrolls through the hundreds of emails he receives each day.

The subject line should also be open ended. The best email appeal subject lines draw the reader in by opening a loop that requires the reader to close the loop. For example, you don’t need to tell the whole story, you only need to open it: Don’t stand by and let this happen to the ocean. What will happen? Why am I standing by? What can I do?
