Klaviyo Email Flow Audit

The problem we audit around

Most Klaviyo accounts we open look healthy on the surface. Revenue attribution shows a reasonable number. A few flows are live. Campaigns ship most weeks. But the founder or head of marketing has a nagging sense that something is off. Revenue per recipient is flat year over year. Welcome series conversion has drifted down. The abandoned checkout flow has not been touched in 18 months and nobody remembers why it routes the way it does. That is the brief most audits come in under.

The second pattern is a team that inherited the account. A prior agency built it, left a spreadsheet, and now the in house team is afraid to change anything because the flows are mysteriously wired with tags and conditional splits that reference profile properties nobody documented. Fear of breaking something keeps the account frozen. Meanwhile the brand grows, the customer base segments in new ways, and the flow logic from 2024 no longer reflects how people actually buy.

The third pattern is deliverability decay. Open rates soft, Gmail placement slipping, Yahoo bouncing a rising share of sends. Nothing is catastrophically broken but the trend is down. An audit is the right first step because you need to know whether the problem is authentication, list hygiene, content, cadence, or something upstream in the sending infrastructure before you spend budget on a rebuild.

Our approach to a Klaviyo audit

1. Access and scoping call. We get view access to Klaviyo, Shopify, and any adjacent tools like Recharge, Smile, or Gorgias. We align on the top three questions you want answered.
2. Data pull and documentation. Every active flow gets diagrammed. Every segment over 500 profiles gets logged with its filter logic. Every campaign from the last 120 days gets exported with send time, audience, revenue, and engagement.
3. Flow logic review. We walk every flow path and check entry rules, exit rules, conditional splits, and suppression. We flag race conditions, dead ends, and paths that suppress engaged buyers by mistake.
4. Deliverability review. DKIM, SPF, DMARC, BIMI, Google Postmaster data, bounce trends, complaint rate, and sending domain structure. We pull the last 90 days of placement data.
5. Revenue attribution review. We reconcile Klaviyo attribution against Shopify order data to confirm no double counting and that attribution windows are sane. We separate flow revenue from campaign revenue and strip out transactional noise.
6. Teardown deck and fix plan. Findings document with kill, keep, and rebuild calls. A 90 day fix plan ranked by effort and expected revenue impact.

What you get

▸ Written audit report covering flows, segments, campaigns, deliverability, and data integrations. ▸ Flow diagram file for every live flow with annotated issues and rebuild notes. ▸ Segment inventory with filter logic documented and use case tagged. ▸ Deliverability health report with DNS verification and inbox placement data. ▸ Campaign performance export for the last 120 days with benchmarks applied. ▸ Ranked 90 day fix plan with effort estimates and expected revenue lift ranges. ▸ Working session with your team to walk through findings and align on priorities. ▸ Decision framework for what to fix in house versus what to scope into a rebuild.

Timeline

Phase one, week one. Access, scoping, data pulls, and flow documentation. You see the raw inventory by end of week.

Phase two, week two. Analysis, teardown deck, and delivery. Working session at end of week two covers every finding and fix plan item.

Some audits extend into a week three when the account has more than 30 active flows or when deliverability data requires a longer lookback. We scope that up front.

Mini case anatomy

A mid tier coffee brand running about 18 million a year in DTC came to us convinced their welcome flow was the problem. Revenue share from email was stuck around 22 percent and they wanted to push into the 30s. The audit found the welcome flow was fine. The real leaks were a broken post purchase flow that was suppressing buyers from every other flow for 90 days, a cart abandon flow that was firing on logged in customers without any exclusion for recent purchases, and a sending domain that had never had DMARC upgraded past monitoring.

We ranked the fixes. The post purchase suppression change alone was estimated to unlock around 6 percent incremental revenue because so many buyers were being blocked from browse and winback flows. Cart abandon cleanup was maybe 2 percent. DMARC upgrade was a deliverability hygiene win with no direct revenue attribution but measurable inbox placement gains.

The team executed the fixes in house using our plan and came back six months later to scope a full rebuild. By then email had moved to around 31 percent of revenue. The audit cost roughly one month of their agency retainer and paid for itself within the first quarter. For a view on the flows that drive most of the revenue, see Klaviyo flows that move revenue. For a deeper breakdown on welcome flow architecture specifically, read Klaviyo welcome series 2026.

If the audit surfaces a rebuild need, the next step is usually a full Klaviyo implementation. Brands with a strong email program but no SMS should scope SMS program launch next. If the audit shows a soft winback flow, pair with a winback program. Everything ladders up to the retention marketing hub.
