Our friends over at Yesware just published a short e-book with 9 data backed email subject line tips. They looked at open and response rates from 115 million emails. What they found are some new email subject line tips, including ones that go against what most of us accept as “best practices”.
Open and reply rates for sales emails
Yesware is primarily used to send sales emails. These are often sent as one-off messages and can be more personal than mass newsletters.
The average open and reply rates tracked by Yesware reflect this. The average open rate for these types of emails was 51.9%. The average reply rate was 29.8%. Both of these are good benchmarks for what to expect when sending sales emails. This is a mix of cold emails and back and forth emails after a relationship starts.
Top email subject line tips

There is a strong correlation between shorter subject lines and higher open rates. Emails with a 50% or higher open rate had 5 or fewer words in their subject lines.
