The one thing to remember
"Not sent" almost never means something is broken. Most of the time it means the system protected you — it refused to message someone who opted out — or the contact's phone or email simply can't receive messages. Only two reasons need action: Needs setup and Temporary delivery issue.

1. Open the Journey Board and pick your main sequenceDock → Journey Board. The headline at the top reads the campaign for you.
-
2. Read the headline firstGreen = running healthy. Orange/red = it names the problem and the step. Trust it — it's computed from the same numbers below.
-
3. Scan the step cards for orange "not sent" footersMuted gray footers ("mostly opted out", "unreachable") are informational. Orange footers ("needs setup", "temporary") deserve a click.
-
4. Click the step and read "Not sent — why"Follow the decision tree above for whichever reason dominates.
-
5. Check "Overdue jobs" in the summary rowA large overdue count concentrated on one channel usually means that channel's sender needs attention — the headline will typically call this out.
-
6. Note the biggest drop-off stepThe banner shows where most contacts stop progressing. That step's message is your best candidate for a rewrite.
Common questions
- Does a big "opted out" number mean my campaign is failing?
- No. It means compliance protection is working. If the rate of opt-outs is climbing sharply, revisit the message content and frequency — but the blocks themselves are correct behavior.
- Why does "currently here" say "estimated" on some very large sequences?
- On rare occasions the exact count can't be computed instantly and a close estimate is shown, clearly labeled. Exact counts return on the next refresh.
- What does "Earlier — reason not recorded" mean?
- Sends from before July 2026, when detailed reason tracking began. Every new non-send carries a reason.
- Who fixes "Needs setup"?
- Usually your workspace admin (Settings → phone numbers / email sender). If nothing looks wrong there, contact support — these are typically resolved quickly.
