Weekly Deliverability Health Checklist
Most deliverability problems are gradual. A 10-minute weekly review catches them at warning-light stage instead of inbox-blackout stage.
- Postmaster Tools Spam Rate. under 0.3% (under 0.1% green zone)
- Microsoft SNDS. Color column is Green for all your IPs
- Bounce rate over the week. under 3% hard, under 5% total
- Complaint rate over the week. under 0.1%
- Spamhaus ZEN lookup on your sending IPs. not listed
- DMARC aggregate (RUA) reports. review for unauthorized senders
- Suppression list grew vs last week. confirms you're processing bounces and complaints
- Send volume vs last week. within ±20% (sudden spikes trigger throttling)
If any check fails, investigate before scaling next week's sends. The cheapest fix is the one made while you're still in the inbox, not after you've dropped into spam.

Benchmarks are averages across other people's email. Outsolvi shows yours, with every open graded so Apple Mail pre-fetches and security scanners don't inflate it. From $7/user/mo billed yearly, 14-day free trial.

FAQ
What's on the weekly list?+
Eight checks: Postmaster spam rate, Microsoft SNDS color, bounce rate, complaint rate, a Spamhaus ZEN lookup, DMARC aggregate reports, suppression list growth, and week-over-week send volume.
Does the page run any of these checks for me?+
No. It's a printed list of what to look at and where the healthy range sits. Each check happens in the provider's own dashboard or lookup, and nothing is monitored or alerted from here.
Why does suppression list growth matter?+
A suppression list that never grows usually means bounces and complaints aren't being processed at all. Steady growth is evidence the plumbing works, and a sudden jump is worth a look.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi grades every open as a person or a machine, in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
We update these pages when the underlying mechanics change. new mailbox-provider rules, new tracker behavior, new measurement gaps. The dates above are real revisions, not auto-touches.
