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'.

Don't fear unsubscribes after trying a new tactic like an emoji. A high unsubscribe rate often means your email finally stood out to a long-disengaged segment. This prompted them to take action and clean themselves from your list, which is a positive outcome for list health.

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.

Email providers track engagement. When many subscribers ignore your emails, algorithms assume your content is low-priority, filtering it to spam or promotions for everyone—even your most loyal followers. A clean list improves deliverability for your entire audience.

Instead of permanently deleting unengaged subscribers, move them to a non-mailing segment within your CRM. This preserves their valuable historical data for tracking and reporting, especially if they were past customers. Many CRMs won't charge for these non-emailed contacts.

An unengaged segment skews your metrics, making you misinterpret what's working. You might change effective content or offers based on artificially low open/click rates. Cleaning your list provides accurate data for making sound strategic choices.

Instead of forcing subscribers to unsubscribe during busy periods like holidays, provide a link that lets them 'snooze' emails for 30 days. This is achieved by applying a temporary exclusion tag via an automation, which boosts retention by giving readers a break without losing them for good.

Instead of randomly contacting a large list of neglected accounts, use modern tools to make an educated guess about where to start. AI can quickly summarize past interactions, identify former buyers who have moved to new companies, or flag potential champions within an organization. This allows for a more strategic and personalized re-engagement effort.

For subscribers who don't open an email, a simple and effective tactic is to resend the exact same content. The only change is tweaking the subject line and pre-header to capture their attention. Since they never saw the original content, it's still new to them and requires minimal effort to redeploy.
