Dan Zarrella, Social Media Scientist at HubSpot, led an insightful & informative webinar this morning on the “Science of Timing: When to Tweet, Email, and Post”.

With 24,000 attendees, this was by far the most engaging webinar I’ve attended — and the hold music before the webinar was almost as good as the info!

Here are some of the key take-aways:

HubSpot — The Science of Timing

* 50% of the U.S. population lives on the East Coast; your marketing efforts should take Eastern Standard Time into consideration.

* Put a blog post up at 11 PM or midnight — you’ll catch your readers first thing in the AM. Blog on the weekends for the most comments.

* Send more email. Unsub rates are the highest when you email infrequently.

* Weekends are best for Facebook shares; 51% of companies block Facebook at work, so evening and Saturday/Sunday interaction is more significant.

* Email your customers between 5:00 AM and 7:00 AM E.S.T. — that has been shown to be the time when emails are opened most often.

* Most retweets occur between 1:00 PM and 5:00 PM EST.
