Email win-back / reactivation series for cold Mailchimp subscribers

Skill harvested 26 Oct 2026. Topic: winning back (or cleanly removing) subscribers who stopped engaging, so the e-book list stays deliverable and honest. Not covered elsewhere: the welcome sequence file handles new sign-ups; subject lines/MPP and cold-email deliverability files handle other parts.

What the practitioner evidence shows

• Dan Oshinsky (Inbox Collective; ex-BuzzFeed newsletters), own list, Feb 2023, read in full: a 3-email series to 1,977 readers who signed up 6+ months earlier and had opened nothing in the previous 90 days won back 361 (18.3%). On the "Last Chance" email, 64% of readers who opened it clicked the stay-subscribed button.
• Same source: a good reactivation campaign wins back roughly 5-15% of the inactive segment, a great one up to 25% (his consulting experience, not a controlled study).
• Litmus guidance (blog, read): give an opt-down or preference choice rather than "unsubscribe or bust".
• Mailchimp Help ("Re-engage inactive subscribed contacts", read): build a segment from email activity or contact rating, then use an automation with post-send actions that unsubscribe or re-tag people who do not respond.
• Secondary figures seen only in search snippets, not checked: "10-15% reactivation" (Deployteq), "12 to 35 percent" (a Facebook group post), "2 to 5% on a first campaign" (Inbox Collective snippet from another post).

Why it matters even for a small list

Mailbox providers place mail partly on how recipients engage. A list where many people never open drags the engaged readers toward the spam folder. Removing non-responders also keeps a free Mailchimp plan (contact cap) usable.

How to run it (Oshinsky's 11-step shape, adapted)

1. Define inactive by cadence: weekly/monthly sender = no opens or clicks for 4-6 months; daily = 60-90 days; giveaway or event sign-ups = 21-30 days.
2. Because of Apple Mail Privacy Protection, judge by clicks where you can. Opens from Apple Mail are machine-made; treat "opened" as weak evidence and "clicked" as the real signal (see email-subject-lines-preview-text-mpp.md).
3. Never include anyone who joined in the last 30 days or has bought. Buyers get a different, gentler note.
4. Email 1 - Preferences / opt-down: "How often do you want to hear from us?" Offer a less frequent option (e.g. only new-edition news).
5. Wait 3-7 days. Anyone who clicks: tag reactivated, exit the journey.
6. Email 2 - Evergreen best-of: 3-4 of the most-read pieces, one line each. Refresh it a few times a year.
7. Wait 5-7 days; same exit rule.
8. Email 3 - Last Chance (opt-in, not opt-out): subject "Do you still want emails from us?"; ONE button ("Yes, keep me on the list"), no other links; plain sentence that nothing needs doing to leave.
9. Wait 4 days. Non-clickers are archived/unsubscribed, not just suppressed.
10. Optional confirmation email: "You've been unsubscribed", with a one-click way back.
11. Build a simple confirmation page for the Last Chance button (thank-you + one next step).
12. Measure: reactivation rate = re-engaged ÷ segment size; then watch whether reactivated people keep clicking over the next 2-3 months. Judge on clicks and sales, not opens.

Mailchimp build: Customer Journey -> starting point "contact enters segment" (or a one-off tag) -> Send email -> Delay -> If/Else on clicked -> tag + exit / continue -> final step "Unsubscribe" or "Archive". Runs on free-plan journeys only if the account's plan allows multi-step journeys; check the plan page before building (not checked).

How we apply it to Cedwyn

• Status today: the Cedwyn/Great House Farm audience is small and young, so there may be no 4-6-month-cold segment yet. Build the journey now as a draft in Mailchimp and switch it on only when a segment of 20+ inactive members exists and the owner gives the GO. Any sending is the owner's decision; this file proposes, it does not send.
• Inactive rule: joined 120+ days ago, no clicks in 120 days, no purchase (match Stripe/Gumroad emails before building the segment).
• Email 1 (preferences): "Only new editions and records finds, or the occasional history note too?" Two buttons -> two Mailchimp tags.
• Email 2 (evergreen): three pieces with one line each, e.g. "The 1824 David Stewart survey: the first record mention found of the farm", "The family acquired Tŷ Mawr in 1667 (1974 newspapers; ITV News 1988)", and the free first edition link on /ebooks/ with utm_source=mailchimp&utm_medium=email&utm_campaign=winback.
• Email 3 (last chance): subject "Do you still want the Cedwyn letters?"; one button to a /thanks/ page that points to the £31.99 bundle on /ebooks/ as the single next step (proposal only; no price change).
• Report: one line in the Sunday growth notes: segment size, reactivated count, archived count.
