(A) Redesign your website
(B) Change the colour of the buttons inside your email
(C) Send your emails to more contacts
(D) Adjust the subject line of your email
The most important part of your email is the Subject line. If your subject line cannot generate enough interest in the user then they will never open your email. If the open rate of your emails seems low, then you should adjust your subject line. You should run A/B tests on your subject lines and constantly check the open rates of emails with those subject lines. The emails with the highest open rates will give you your best subject lines.
