Case Brief

Yahoo Is Quietly Clipping Your Reach

Over the last few weeks and months, many publishers have seen dips in open and click rates isolated to Yahoo/AOL addresses. The cause is a mix of tighter spam filtering and new reputation signals. This brief shows how to confirm you're impacted and restore inbox placement with a paced re-warm and engagement-first targeting.

Today's orders: segment Yahoo traffic, stabilize volume, suppress inactives, reduce complaint risk with one-click unsub, and A/B a plain-text-lean variant to reestablish trust fast.

Primary Diagnosis

Inconsistent Volume + Low-Intent Cohorts = Yahoo Throttle

Yahoo's filters reward steady cadence and penalize erratic sends. If engagement slips (esp. from co-reg or older inactives) while volume spikes, Yahoo treats your mail as "gray"—throttling or bulk-foldering even clean lists.

  • Volume spikes: big batch jumps reset reputation and trigger delays.
  • Low engagement: inactives + mixed-intent sources drag down sender score.
  • Complaint sensitivity: keep visible spam complaints well below ~0.2%.
Related: our Gmail Manage Subscriptions guidance still applies—clear off-ramps lower complaints when filters surface unsub options.
Secondary Factors

Heavy tracking strings in visible link text, image-heavy layouts, inconsistent "From" names, and lack of a one-click unsub inflate risk. Keep anchor text semantic and reduce above-the-fold link clutter.

Risk gauge: [■■■■■□□□] ~60% chance of Yahoo CTR drag without a paced re-warm + suppression
Treatment Plan (Ship This Week)
1) Segment & Pace Volume
  1. Isolate: send Yahoo/AOL on their own campaigns.
  2. Stabilize: cap increases to ~20%/week while watching KPIs.
  3. Schedule: consistent daily/near-daily cadence beats sporadic blasts.
2) Engagement-First Targeting

Suppress Yahoo readers inactive > 60 days. Start with your most active cohort, then gradually re-include warm segments as metrics normalize.

3) Complaint Reduction Essentials

Use recognizable From names, match subject + preheader to content, keep a one-click unsub prominent, and avoid surprise frequency changes.

4) Content & Infra Checks

A/B a plain-text-lean intro vs. design-heavy. Shorten visible link text (semantic, not UTM soup). Confirm SPF/DKIM/DMARC alignment and monitor Yahoo Postmaster for errors.
