How to Re-Engage Subscribers Who Have Gone Cold

It’s a familiar sight for any email marketer: a segment of your email list that was once active is now silent. These are your cold subscribers: people who haven't opened or clicked an email in months. While it might be tempting to write them off, re-engaging these subscribers can be a powerful way to win back customers and clean up your list.

Here’s how to re-engage subscribers who have gone cold.

Identify Who Is Truly Cold

First, you need to define what "cold" means for your business. The right timeframe depends on your industry and how often you send emails. For a daily newsletter, a subscriber might be considered cold after a month of no engagement. For a business that emails once a month, you might want to look at a 6- to 12-month window.

Create a segment in your email service provider for subscribers who haven't opened or clicked an email within your chosen timeframe. This is the group you'll target with your re-engagement campaign.

Create a Re-Engagement Campaign

A re-engagement campaign, often called a win-back campaign, is a series of emails designed to get your cold subscribers to interact with your brand again. This isn't the time for your usual marketing messages. The goal is to remind them why they subscribed in the first place.

Here are a few types of emails that work well in a win-back campaign:

  • The "We Miss You" Email: This is a straightforward approach. Acknowledge their absence, remind them of the value you offer, and ask them to come back. You could offer a special discount or a free resource as an incentive.

  • The Update Email: Has your business changed since they last engaged? Maybe you’ve launched new products, updated your services, or published some great content. Send an email highlighting what’s new and exciting.

  • The Feedback Request: Ask for their opinion. An email that asks, "What can we do better?" or "What content do you want to see?" can be very effective. It shows you value their input and gives you insight into why they may have disengaged.

  • The Preference Update: Give subscribers control over how often they hear from you. Send an email that links to your email preference center. This allows them to choose the topics they're interested in or reduce the frequency of emails instead of unsubscribing completely.

Your campaign should consist of a few emails sent over a couple of weeks. A single email can easily get lost in a crowded inbox.

Write Compelling Subject Lines

The subject line is your first and often only chance to get a cold subscriber's attention. Generic subject lines won't work here. You need something that stands out and creates curiosity.

Try subject lines like:

  • We miss you. Here's a 20% off coupon.

  • Has our content been helpful?

  • A lot has changed since you've been gone.

The goal is to be direct and personal. Use their first name if it fits your brand's tone. The key is to make them feel seen and give them a reason to open the email.

Know When to Let Go

Not every subscriber can be won back, and that’s okay. Holding on to unengaged subscribers can harm your email deliverability. Internet service providers track how recipients interact with your emails. A high number of unengaged contacts can signal that your emails are unwanted, which may cause them to be routed to the spam folder.

At the end of your re-engagement campaign, it’s time to say goodbye to those who still haven't responded. Send one final email letting them know you'll be removing them from your list unless they click a link to confirm they want to stay. This is a final, clear call to action.

After that email, remove any remaining non-responders from your active list. This process is essential for maintaining a healthy and effective email marketing program.

Win Back Subscribers and Improve Your List

Re-engaging cold subscribers is a smart strategy. It can bring lost customers back into the fold and provide valuable feedback. More importantly, it forces you to practice good list hygiene, which improves your sender reputation and ensures your emails reach the people who actually want to hear from you.

Start by identifying your cold subscribers, create a targeted campaign to win them back, and be prepared to let go of those who are no longer interested. Your email list will be stronger for it.
