Scoring & Research

Why aren’t messages being sent?

When sending stops, do not restart or duplicate the campaign immediately. Record the affected list, lead, status, sender, channel, and expected time, then check one layer at a time.

Before you start

  • Keep the current campaign and history intact.
  • Choose one working and one blocked lead for comparison.
  • Do not change multiple settings at once.
  • Never share passwords, tokens, cookies, or API keys with support.

Five common causes

The lead is not send-ready, no active campaign is assigned, the sender is disconnected, a channel or daily limit is reached, or the step is scheduled for later. Exclusions, duplicates, missing email, or channel-specific conditions can also block it.

Scheduled is not immediate

Scheduled means the step is planned. The actual time depends on sequence timing, send delays, allowed windows, sender state, and available capacity.

Steps

  1. Open the lead and check score, status, exclusion reason, and campaign assignment.
  2. Open Review Leads and confirm the sequence is complete and approved.
  3. Check the assigned LinkedIn or email account under Users.
  4. Compare Outbox entries under Scheduled and Sent.
  5. Review daily limits, send delays, permitted windows, and campaign state.
  6. Compare a working lead with a blocked lead field by field.
  7. If unresolved, pause changes and send support the list, anonymized lead ID, statuses, timestamps, and screenshots.

Safety checks

  • The recipient and relationship history are correct.
  • The authorised sender and connected channel are selected.
  • Copy, language, sequence, limits, delays, and timing were reviewed.
  • Other Lists, previous outreach, opt-outs, blacklists, and exclusions were checked.
  • A small test will be monitored before volume increases.

Frequently asked questions

Should I duplicate the campaign?

No. Duplication can obscure the cause and risk duplicate outreach.

Why is Scheduled not sending now?

The planned time, delays, windows, limits, or sender state may intentionally postpone it.

Where do I check the sender?

Use the current user or sender settings and confirm the account assigned to the campaign is connected and authorised.

What information should support receive?

List, anonymized lead ID, campaign, sender reference, statuses, expected and observed times, and safe screenshots.

Should I reconnect the account immediately?

Only when the current status and approved process indicate it; avoid simultaneous account and campaign changes.

Can a missing email block only some leads?

Yes. Compare the channel data and validation state of working and blocked leads.
