19 Tips to Boost Your Email Opening Rates by 29

Do you want to increase your Email opening rates?  Boost email sales?  Achieve better ROI on your funnel email series?

High Email opening rates are accomplished by marketers and copywriters who craft email subject lines that are irresistible.

1.  So How Many Emails Do We Delete on Average?

On average, we delete 48% of the emails we receive every day.  Deleting emails takes us about five minutes.  Multiply that number by a year, and you get over thirty (30) hours a year spent deleting emails.

You can see why we opt out of subscription lists when we are spammed regularly, with content that has no apparent benefits and value to us.

The optimal way to write email subject lines is to appeal to our human predispositions, greed, we all want the best deal.  Urgency, the countdown to the end of a sale appeals to our fear of missing out!  Well-crafted subject lines hook us into opening the Email.

First, we need to know a little bit about our target audience.

2.  Prospects Are Early Birds, Are They?

Your target market will determine the best time and day to send out your Emails though many people read emails between 5 and 6 a.m.  Professionals and science suggest that Tuesday at 10 a.m. is the best time.  Before you rush to a conclusion, we must look at opens, clicks, and responses.

B2B emails to entrepreneurs, otherwise known as workaholics, will compulsively check and respond to emails every day.  Interestingly Weekends may yield higher opening rates when the overachievers relax.
