Most teams do not need a new dashboard. They need ten minutes to find out whether the one they already have is actually working. 1ClickReport's 2026 guidance is a useful starting benchmark: a functioning KPI dashboard generally tracks 10 to 15 metrics at most, since anything beyond that dilutes focus rather than adding clarity. The checklist below is organised the same way a healthy dashboard should be, revenue first, engagement second, list health third, so you can see exactly where a weak answer sits and what it is quietly costing you.

How to use this

Open your current reporting and work through the six questions below in order. If you cannot answer a question within about ten seconds of looking at your dashboard, without exporting anything or asking someone else, that is a gap, not a pass. Count your gaps as you go.

Tier 1: Revenue, is email actually making money?

• Can you state revenue per email for your last campaign without doing the calculation yourself?
• Do you know your total attributed email revenue for the trailing 30 days, and is it broken out separately from other channels?

Tier 2: Engagement, are people interacting with what you send?

• Does your dashboard show click-to-open rate, not just open rate, front and centre?
• Can you compare this month's engagement against last month's without exporting data into a spreadsheet first?

Tier 3: List health, are you protecting future revenue?

• Do you know your current bounce rate and complaint rate off the top of your head?
• Do you know your monthly list decay rate, and whether it is running inside or outside the roughly 2% a month considered normal attrition?

Why open rate cannot be the anchor metric anymore

If Tier 2 was a gap, it is very likely because open rate is still the headline number. Bloomreach's 2026 guidance notes that a genuinely good open rate now sits somewhere in the low 30s to low 40s depending on source, largely inflated by Apple's Mail Privacy Protection, which is why click-based and revenue-based metrics have become the more trustworthy anchors for any 2026 dashboard. Open rate still has a use, covered in our post-MPP reporting article, but it should not be the number your team checks first.

Why list decay showing up is not automatically bad news

If Tier 3 flagged a decay rate you were not tracking, check it against Bloomreach's 2026 benchmark before treating it as a crisis: natural annual list decay runs around 22.71%, roughly 1.89% a month. A number inside that range is expected. A number running well ahead of it, 2 to 3% a month or more, is the one worth investigating.

A sensible cadence once the gaps are closed

Hustler Marketing's 2026 guidance recommends checking KPIs weekly, with a deeper monthly review, rather than daily. Daily fluctuation is mostly noise that tempts overreaction to a single unusual send. A separate 2026 survey of financial advisory firms found teams updating dashboards weekly saw meaningfully better marketing ROI than those reviewing data monthly or quarterly, which points to a consistent weekly check as the useful middle ground.

Mail Blaze's comparative filters let you set two campaigns or two segments side by side directly in your dashboard, so Tier 2's 'compare against last month' question has a real answer without an export.

Frequently asked questions

What if I fail most of the checklist?

Start with whichever tier has the most gaps rather than trying to fix all three tiers simultaneously. Revenue gaps are usually the most urgent, since they affect whether you can prioritise anything else with confidence.

How many metrics should an email dashboard track?

Most 2026 guidance recommends 10 to 15 at most for an operational dashboard, and as few as 5 to 8 outcome metrics for an executive-level view.

Should open rate still be on the dashboard at all?

Yes, but not as the primary metric. It remains directionally useful, particularly for spotting deliverability problems, but click-based and revenue-based metrics are more trustworthy anchors in 2026.

How often should I re-run this checklist?

Once a quarter is reasonable for most teams, or any time you change platforms, restructure your reporting, or notice a metric you cannot immediately explain.

Mail Blaze is an email marketing platform specialising in email engagement, with reporting built around the metrics that actually drive a decision, not a wall of vanity numbers.
