Counterintuitively, highly formatted and image-heavy emails can feel corporate and impersonal, decreasing engagement. Shifting to a simpler, plain-text style mimics a personal message from a friend, which increases perceived authenticity and encourages more replies and genuine connection.

Frame email subject lines to appeal to the higher-level position your audience desires. A manager wants to know what a CMO is doing. This psychological tactic, which plays on ambition, can lift open rates by 24-28% over standard personalization by speaking to who your audience wants to become.

From Nov 20th to Dec 20th, sending a personal letter-style email from a founder or executive to unengaged contacts can increase open rates by 40%. The key is changing the "from name" to a person, not the brand, and using a subject line that acknowledges their absence. This strategy works for both B2B and B2C brands.

Combine two specific audience identifiers in your subject line, like role and company attribute ("Mid-market CMOs") or interest and a pain point ("Beauty fans with sensitive skin"). This "double personalization" tactic reportedly increases B2B open rates by 24% and B2C by 29% by making the message feel hyper-relevant.

Don't fear that AI summaries in Gmail and Apple Mail will kill your open rates. If your content is genuinely valuable, people will still open it to get the full experience, just as they'd watch a favorite show instead of reading a synopsis. AI simply helps users filter out the noise.

Explicitly telling users what action to take in marketing copy taps into their subconscious willingness to follow instructions. Simple commands like 'open this,' 'save this post,' or 'screenshot this' prompt users to act, leading to measurable lifts in metrics like email opens and post saves on platforms like LinkedIn.

Personalizing subject lines with a recipient's industry or interests is a known tactic that provides a solid 20% lift in open rates. However, this should be considered a baseline, as more advanced psychological tactics like aspirational messaging can yield even higher returns of 24-28%.

Switching from clear but safe subject lines (e.g., '3 ways to...') to provocative, curiosity-piquing ones dramatically improved open rates. The speaker notes that if a subject line feels slightly uncomfortable to send, it's probably a good sign.

A counterintuitive yet effective email tactic is capitalizing an entire word in the middle of a subject line, not at the start or end. This simple, cost-free A/B test is trending because it breaks visual patterns in the inbox, leading to a reported 16% open rate increase for B2B and 21% for B2C.
