A highly effective email tactic is using a compelling statistic as the entire subject line, with no other text or call to action. This piques curiosity by presenting a data-driven statement, leading to an average open rate increase of 19%.
"Deliverability" simply means an email reached the mailbox, not the inbox. Actual inbox placement averages 83.5%, so it's normal for about one in six emails to land in junk or spam folders. This data helps marketing teams set realistic internal expectations.
For podcast advertising, having the host read the ad copy is far more effective than using a generic, pre-recorded ad. Nielsen data shows this host-read approach results in 68% higher brand recall, as the endorsement feels more authentic to the audience.
