Take personalization emails a step farther, and you can customize your call to action (CTA). Focus on understanding buyers and how their roles fit within their organizations. For example, a marketing director and a technical director may have entirely different goals and perspectives when they open up your email. If you offer a unique CTA for the two groups, they are more likely to engage with your email and more likely to convert.
When it comes to deciding how to craft that perfect subject line, there appears to be really only one area to avoid: the subject line of 60 to 70 characters. Marketers refer to this as the “dead zone” of subject length. According to research by Adestra, which tracked over 900 million emails for its report, there is no increase in either open rate or clickthroughs at this 60-to-70 character length of subject line.
