Troubleshooting Email Sending Issues

If a campaign has stopped sending or is sending less than expected, work through these checks in order. Most sending issues have a straightforward cause.

1. Check account connection status

Go to Deliverablity. Disconnected accounts show a red error badge and stop contributing to campaign sends. Reconnect any disconnected accounts before checking anything else.

2. Check daily sending limits

Go to your Sequences → Campaign and Settings and verify the per-account and per-campaign daily limits. A limit of 0 — or no accounts assigned — will prevent all sends. Also check that your account-level limits haven't been reduced via Bulk Edit Settings.

3. Check campaign status

The campaign must be in Active status to send. Paused campaigns hold all sends. Campaigns in draft have never been launched. Check the campaign status badge on the Campaigns overview page.

4. Check the sending schedule

In campaign Options, verify that:

  • Today's date falls within the campaign's start and end date range

  • The current time is within the configured sending window

  • The current day of the week is enabled in the schedule

5. Check lead status

In the campaign's Lead List, check whether leads are in a status that blocks sending — Bounced, Unsubscribed, or Removed. If all leads have a non-sending status, the campaign will appear active but send nothing.

6. Check for DKIM or authentication errors

In Email Accounts, look for any accounts showing DKIM or authentication errors. Emails from accounts with authentication failures may be rejected before reaching leads.

If none of the above resolves the issue, contact support via in-app chat or support@stamina.io with your campaign name and account email addresses.
