More than half of online adults in the U.S. aged 65 or over are now using Facebook, reveals a new study.

This compares to just 10 percent of seniors who are using Twitter.

Additionally, 63 percent of U.S. online adults aged 50-64 are also active on Facebook – more than five times that of Twitter (12 percent).

Twitter’s strongest demographic is the 18-29 age group, but it’s still dwarfed by Facebook and also Instagram in this vertical.

Sometimes you just don’t have the time or resources to meticulously test your blast emails, but that doesn’t mean you can’t maximize your results with proven tactics.

Here are some simple tips that I think smaller, and medium sized campaigns and organizations can put in place, right now, to improve their blast emails.

1. You have to make it matter. One of the biggest mistakes writers make is not relating the importance of what they are asking supporters to do.

Facebook conducted two experiments with Democratic Senate campaigns this year to see if advertisements on its site encouraged people to make political contributions.

For all those refcode-happy committees, this feature’s for you! Now you search for a specific refcode on the Contribution Form statistics page.

There are two ways to get to that page (and both require you to be logged in): if you’re already on your Contribution Form, go to the Contributors tab, and click on “View Form Statistics” or just insert your Contribution Form name into the url below:

secure.actblue.com/pages/CONTRIBUTION_FORM_NAME/statistics

To try out the new feature, just type in all or part of the refcode you want to see, and you’ll find only those refcodes that match your search.
