Diagnostic & Repair

Sequences are firing. Contacts aren't getting them.

→ DIRECT ANSWER

Lifecycle emails fail to send for predictable reasons: workflow logic dropping contacts, segmentation excluding the wrong people, deliverability issues silently routing to spam, or sequence-conflict suppression. The fix is observability + workflow audit + deliverability hardening — not a different platform.

02CAPABILITY LAYER

Why this symptom is a Marketing Systems problem.

Lifecycle email failures are usually invisible until pipeline drops. Most teams discover them weeks late when reactivation rates collapse. The architecture fix is observability — every send tracked, every drop diagnosed — paired with a workflow audit that surfaces logic errors hiding in plain sight.

Symptoms

If most of these are true, you have it.

01Sequence shows "active" but contacts report no email

02Some contacts get sequence; others don't — no clear pattern

03Welcome email lands in spam for 30%+ of recipients

04Reactivation campaigns send but generate no replies

05Workflow logs show "skipped" without reason

06Deliverability data is unmonitored or unavailable

Likely causes

Three patterns that produce most cases.

CAUSE · 01

Workflow logic dropping contacts

Filter conditions exclude the contacts you meant to reach. Most-common: "if email is opted-in" missing the contacts who opted in via a different channel.

CAUSE · 02

Deliverability silently failing

SPF/DKIM/DMARC misconfigured, sender reputation poor, content triggering filters — emails "send" but never inbox.

CAUSE · 03

Sequence-conflict suppression

Multiple sequences trying to fire on the same contact get suppressed by platform conflict logic. The send appears successful in one place; another silently drops it.

Recovery process

A 14-day lifecycle recovery sprint.

01 · DAYS 1–5

Audit + observability

Inventory every active workflow + segmentation rule. Stand up send-level observability. Identify drop points.

02 · DAYS 6–10

Workflow + deliverability fix

Fix logic errors. Lock SPF/DKIM/DMARC. Resolve sequence conflicts. Test send to known recipients.

03 · DAYS 11–14

Verify + monitor

Confirm contacts receive sequences. Stand up monitoring + alerting. Hand off operator playbook.

FAQ

Questions we get asked.

01Why are some contacts getting the sequence and others not?+

Almost always: filter or segmentation logic excluding contacts you meant to include. Workflow audit surfaces this within the first week.

02Is this a deliverability problem?+

Sometimes. SPF/DKIM/DMARC misconfiguration is the second most common cause. We test inbox placement to known recipients to confirm.

03Should we move to a different platform?+

Almost never the answer. The same logic + deliverability problems follow you to the new platform. Fix the architecture in your current platform first.

04How fast does deliverability recover?+

Authentication wins (SPF/DKIM/DMARC) are immediate. Sender reputation lift takes 30–60 days of consistent engagement-positive sending.

05Will this work in HubSpot / Klaviyo / GHL / ActiveCampaign?+

All of them. Architecture is platform-agnostic; the implementation differs. We have shipped this on every major lifecycle platform.

06How do we prevent this from happening again?+

Observability + monitoring. Every sequence is tracked send-by-send. Drops trigger alerts. The system tells you when it's degrading.

07What about SMS sequences in the same problem?+

Same architecture, same diagnostic. We address SMS in the same engagement when it shares the lifecycle stack.

08How is this related to attribution / GA4?+

Lifecycle emails feed the conversion path tracked in GA4 + CRM. If lifecycle is broken, attribution will look broken too. We address them together when both are flagged.
