Email marketing is one of the cheapest forms of digital marketing. But is it really business-impacting if only a handful of receivers open your emails?

In this blog, we talk about the most important metric in email marketing – open rate & how to increase email open rate for your marketing campaigns.

But first, let’s understand what the open rate is.

An email is counted as open only when receivers open your email from the inbox. 

The email open rate is then calculated by dividing the opened emails by the total number of emails sent that did not bounce, divided by 100. 

For example, if out of 1000 emails sent, 70 receivers open the email, the email open rate will be 70/1000*100 which is 7%.
