Hi guys! I want to share a quick excerpt from Mailchimp's research here.
MailChimp conducted an investigation and analyzed millions of e-mail subject lines. They have found that 1 word increases the opening rate by 57% for all users on average.
Here you can see what you can earn or lose when you use specific words in your subject line.

Free: + 2%
Freebie: + 26%
Urgent: + 79%
Thanks: + 57%
Negative impact on the opening rate:
Canceled: -40%
Helping: -12%
