![Email Forward-To-Open Rates, June 2015 [CHART]](https://trends.e-strategyblog.com/wp-content/uploads/2015/09/Litmus-Email-Virality-by-Audience-Size-Jun2015.png "Chart - Email Forward-To-Open Rates")
Virtually all (95% of) commercial emails generate some forwarding behavior, according to a Litmus analysis of more than 400,000 commercial sends with at least 500 opens between January 2013 and March 2015. The median email (by forward-to-open rate) generated 1 forward for every 370 opens, or a 0.27% forward-to-open rate, per the analysis. However, there is exponential growth in this rate when looking at the top percentiles, with the top 1% being 17.6 times more likely to be forwarded than the median, generating 1 forward for every 21 opens.
Interestingly, the analysis found that the forward-to-open rate was higher for emails with small audiences (those with 500 to 50,000 opens) than for those with larger audiences, which the study author attributes to smaller audiences tending to “coalesce around narrow interests, specialty products, niche services, and local attractions.” Source: Litmus
