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.

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.

While many marketers use brackets at the beginning of email subject lines, new data from subjectline.com shows placing them at the end is boosting open rates. This tactic works by drawing the reader's eye to a key callout, and contrary to myth, it does not negatively impact deliverability or land emails in spam.

A subtle but powerful formatting trick in emails and landing pages is to hyperlink an entire sentence or phrase, not just one or two words like "click here." This creates a larger, more obvious clickable target for the user, improving the experience and likely increasing clicks.

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%.

Rephrase call-to-action buttons from a brand command (e.g., "Donate Now") to a user's first-person statement (e.g., "Yes, I want to help"). This simple change in perspective makes the user an active participant, significantly increasing engagement and click-through rates on emails, landing pages, and social media posts.

Data from Subjectline.com reveals a powerful, simple tactic for email marketing. Using a "continuation pre-header" that begins with "and," "but," or "plus" creates a narrative link to the subject line, sparking curiosity and significantly boosting open rates. This is an easy-to-implement test for any campaign.

From October 1st through year-end, starting email subject lines with "Invitation" or "Invited" can boost open rates by 24% (B2C) to 28% (B2B). This tactic taps into the subconscious holiday season mindset where people are more receptive to being invited, whether to a sale, an event, or a piece of content.

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.
