Using subject lines like "Verify your active status" can lift open rates by 27-31% for contacts who haven't engaged in over a year. While effective for reactivation, this slightly gimmicky approach will also annoy some users, leading to a higher-than-usual unsubscribe rate and negative replies, which requires 'thick skin'.

To win back inactive subscribers, send a short sequence (2-3 emails) with direct, urgent subject lines like 'Should I stop emailing you?'. The email body should be simple: acknowledge their absence and provide one clear button to click to stay subscribed. This cuts through the noise they've been ignoring.

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.

Many marketers mistakenly summarize their entire email in the subject line, removing any incentive to open it. To increase curiosity, provide only a hint or a compelling data point from the email's content. This creates an information gap that subscribers feel compelled to close by clicking.

Subject lines that suggest an internal mistake or conflict, such as "We forgot to end this sale," create a feeling of insider access for the recipient. This "accidental reveal" tactic builds urgency and exclusivity, driving higher engagement.

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%.

Marketer Jay Schwedelson argues that non-openers are distracted, not disinterested. He advises resending the same email within 48 hours but with a new, aggressive subject line that creates urgency (e.g., 'Yikes, you scrolled past this'). This gives the message a second chance to cut through the inbox noise.

Instead of guessing why open rates are low, the first diagnostic step should be a disciplined A/B test. Experiment with two different subject lines to gather data on what captures your audience's attention before changing anything else.

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.
