Avoid list-cleaning automations with a small subscriber base (e.g., under 1,000). Instead of deleting inactive subscribers, personally email them to ask what they're struggling with. This approach turns a technical cleanup task into a valuable user research and re-engagement opportunity.

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.
For B2B re-engagement, a highly effective subject line is "Are you still with [Company Name]?". This personalizes the email at scale by dynamically inserting the contact's employer. It grabs attention and prompts an open to confirm or update their status, successfully re-engaging them with your content or offers.
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.
Systematically call every customer who has churned, not to win them back, but to thank them and understand why they left. This provides invaluable, unfiltered market research. By the 19th call, you'll have identified core product or service issues that data alone cannot reveal.
A sudden increase in unsubscribes after a marketing change isn't necessarily a failure. It often means you've successfully grabbed the attention of disengaged subscribers who then self-select out because the content is no longer relevant, which is a healthy outcome for your list.
Prompting subscribers with simple, non-work-related questions (e.g., "What's your favorite holiday cookie?") encourages replies. This builds a conversational relationship, improves engagement signals, and positively impacts email deliverability and open rates.
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.
Incorporate simple, conversational questions into emails to encourage replies. This engagement signals to email service providers that your content is valuable, improving deliverability. It also helps build a stronger relationship with your audience by starting a two-way conversation.
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.
