How do you re-engage an audience that’s gone quiet while keeping your email list healthy?
At Speakers for Schools, I faced the inevitable challenge all marketers encounter, a growing list of inactive contacts.
It wasn’t just about clearing out disengaged subscribers, it was about giving them a chance to reconnect and making sure every email we sent brought value.
Here’s how I approached the task.

Brief:
To re-engage inactive contacts and clean the email list by unsubscribing those no longer interested, within two months.
Challenges:
Inactive contacts aren’t just a vanity issue, they impact deliverability, skew analytics, and risk being marked as spam.
The biggest challenge? Finding the balance between clearing out unengaged users and giving them one last opportunity to rejoin.
Our list was full of potential, but the key was identifying who wanted to stay, and who was ready to leave.
Strategy:
I created a two-email Sunset Flow in Iterable to engage inactive contacts and simplify unsubscribing. The strategy prioritised clarity, respect and transparency:
Emails with straightforward messaging and clear calls-to-action.
Acknowledging the value of subscribers’ time and preferences.
Making it easy for them to stay or leave without guilt or pressure.
Implementation:
The Sunset Flow featured two key touchpoints:
Email 1: ‘Stay Connected with Us!’
- A warm and understanding message acknowledging inactivity.
- Clear options to update preferences, remain subscribed, or unsubscribe.
Email 2: ‘Your Last Email from Us, Unless You Want to Stay’
- A final message with a friendly tone.
- A subtle nudge to engage or opt out before being automatically unsubscribed.
Each email was optimised for simplicity, including concise copy, a single CTA, and dynamic personalisation to keep it relevant.

Tracking & Reporting:
To measure the effectiveness of the flow, we tracked key metrics:
- Open rates to identify interest levels.
- Click-through rates to gauge engagement with the “Update Preferences” button.
- Unsubscribes to monitor list-cleaning progress.
I analysed these metrics after each email to make data-driven decisions for optimisation.
Optimisation:
Testing and tweaking the flow made all the difference:
- Subject lines
I ran A/B tests to increase curiosity and urgency. - CTA design
Enhanced visibility and simplicity of buttons. - Timing
Adjusted email delays for better engagement.
The iterative approach ensured the next email performed better than the previous.
Results:
26%
inactive contacts re-engaged
17%
list unsubscribed
57%
automatically unsubscribed
- 26% of inactive contacts re-engaged, opening at least one email.
- 17% of the list unsubscribed, leaving behind a healthier, more engaged audience.
- 57% of inactive contacts were automatically unsubscribed due to long inactivity, improving deliverability and boosting open and click rates in future campaigns.
Takeaways:
Building trust starts with respecting user preferences and making it easy for subscribers to either stay or leave. Metrics are invaluable for guiding decisions and ensuring continuous optimisation.
Clarity and simplicity in communication are essential, and transparency is key to achieving better re-engagement results.
