If you’ve ever squinted at your stats and wondered, ok but what actually hit the inbox, Yahoo finally opened the curtains. Their new Insights view in Sender Hub shows the numbers that matter, calculated off inbox-delivered mail, so you see the complaint rate users actually triggered, not a fuzzy estimate. That’s the headline.

Quick start

  1. Create or sign in to Sender Hub. Head to Yahoo Sender Hub, then open the Dashboard.

  2. Add your sending domain. Click Add Domain, copy the TXT record Yahoo gives you, add it to DNS, then return to complete verification.

  3. Wait for it to populate. Data usually appears after the domain is verified and sending volume is high enough, typically within about a day. Don’t panic if it isn’t immediate.

(Tip: if you manage multiple subdomains, verify each one you care about. Ownership is per domain, and you can repeat the TXT step for more than one account if your team won’t share a login.) 

What you’ll see

  • True complaint rate, day by day. This is based on inbox-delivered messages, not total sent, which gives you a cleaner signal when you’re troubleshooting spikes.

  • Delivered volume. Daily totals to Yahoo and AOL recipients, with history that currently goes back as far as 180 days. Helpful for spotting pattern changes after a content or cadence shift.

  • Inbox vs spam context, via feeds. If you need programmatic reporting beyond the dashboard, Yahoo’s Placement Feed breaks out inbox, spam, and folders. Handy for deeper diagnostics.

Why it matters

Complaint math can be slippery when the denominator includes spam-folder mail. Yahoo’s approach removes that noise, so you’re reacting to what users actually saw. That’s a much closer read on reputation and placement risk.

And the guardrails are clear. Aim to live under 0.1 percent on complaints, and don’t ever cross 0.3 percent. Above that, you’re inviting throttling or filtering. Set your alerts accordingly.

How to use Insights week to week

  • Watch the threshold. Add a simple rule in your tracker: flag any day above 0.1 percent, and escalate if a rolling average nudges 0.2 percent. You want breathing room before 0.3 percent.

  • Correlate spikes. When complaints jump, check the send that day, list source, and subject line. If volume dipped but complaints stayed flat, your rate will look worse, so inspect the denominator too.

  • Pair with content tests. If inbox placement softens or complaints rise, try a lighter touch for 2 sends: calmer frequency, plainer subject, and a bigger preference link. Rebuild engagement, then scale.

  • Document changes. Keep a simple change log next to your Yahoo trend line, so you can connect cause and effect without guesswork. Future you will thank you.

Benchmarks and next steps

  • Targets: stay at or below 0.1 percent, treat 0.2 percent as a yellow light, and never exceed 0.3 percent.

  • Cadence: check the Yahoo line weekly, then monthly. If you run promos, monitor during launch weeks and the week after.

  • Add the feed if you need depth: engineering or ops can wire the Placement Feed for inbox vs spam reporting alongside ESP data.

If you’re serious about deliverability, make this dashboard part of your regular ritual. Less guessing, more decisions grounded in what users actually did.
