Introduction¶

The piece addresses a critical challenge for senders: "Spam filters got smarter. AI is watching every send." The author outlines a technical strategy for re-engaging dormant contact lists without damaging sender reputation.

The 9 Ways¶

1. Never Warm Up on Your Primary Domain¶

Senders should avoid blasting dormant lists from their main business domain. Instead, utilize separate IP addresses through platforms like Constant Contact or dedicated sending partners to create "a firewall between your warm-up experiments and the email domain."

2. Use a Secondary Domain — But Not a Brand-New One¶

Fresh domains lack credibility with mail servers. The recommendation is leveraging older backup domains (purchased 1-2 years prior) that appear brand-relevant. This requires advance planning.

3. Get Your Authentication Airtight¶

SPF, DKIM, and DMARC configuration is essential before sending. Google Postmaster Tools registration provides visibility into domain reputation and authentication status.

4. Your First Email Should Ask for Absolutely Nothing¶

Initial messages must provide pure value — informational content without sales pitches or calls-to-action. This establishes legitimacy before making asks.

5. Ramp Volume Gradually¶

Start with 10 messages daily, increasing incrementally to 50 over weeks. A 60-90 day warm-up period is typical before scaling campaigns.

6. Skip Tracking Pixels Early¶

Avoid embedding tracking elements in initial sends from new domains, as these raise spam filter suspicion.

7. Treat Hard Bounces Seriously¶

Remove hard-bouncing addresses immediately. Each bounce carries disproportionate weight during low-volume warm-up phases.

8. Engineer Replies on Third Send¶

Genuine engagement signals — actual replies from recipients — build credibility faster than passive metrics.

9. Play the Long Game¶

Establish trust through incremental value delivery before requesting conversions. The philosophy prioritizes patience and relationship-building.
