If your campaign isn’t sending emails, it’s usually due to one of the reasons below. Check the associated campaign status in Hunter to identify the cause and follow the fix.
1. Campaign is Paused or Completed
Status: Paused or Completed
Paused: Emails stop sending until you manually reactivate the campaign.
Completed: All emails in the campaign have been sent. If you add new recipients, the campaign becomes “evergreen” and will send emails to them automatically.
Fix:
If paused, click Activate to resume sending.
If completed, add new recipients to trigger new sends.
2. Outside of the Sending Window
Status: On hold – Outside of sending window
Why it happens: The campaign is scheduled to send only on specific days/hours, and it’s currently outside that window.
Fix:
Open your campaign and adjust the sending window from the Settings tab. If you prefer to keep the current window, simply wait for it to send as scheduled.
3. Daily sending limit Reached
Status: On hold – Waiting for sending limit reset
Why it happens: The email account reached its daily send limit.
Fix:
Go to Email Accounts Settings and edit the daily limit to increase it (recommended: 15/day for new accounts).
Or wait until the limit resets automatically at midnight (account time zone).
🕒 The daily sending limit resets at midnight (00:00 AM) based on the account’s time zone.
4. Campaign is preparing
Status: Preparing
Why it happens: New campaigns take a few minutes to schedule emails before sending starts.
Fix:
No action needed. Emails will send automatically once preparation is complete.
5. Sending account disconnected
Status: Error – One or more email accounts have been disconnected
Why it happens: One or more connected email accounts lost their connection.
Fix:
Go to Email Accounts Settings.
Click Reconnect for the affected account(s) and follow the steps.
Once reconnected, the campaign will resume.
6. No email account assigned to campaign
Status: Error – This campaign has no email accounts
Why it happens: No sender account is linked to the campaign.
Fix:
Click on the campaign.
In the Settings tag, select one or more email accounts in the Sender accounts section (or connect a new one).
The campaign will resume automatically unless paused.
7. Other campaigns are sending first
Status: On hold – Waiting for other campaigns
Why it happens: Another campaign using the same email account is ahead in the sending queue. Older campaigns are always prioritized over newer campaigns.
Fix:
Pause other active campaigns using the same account.
Once paused, the current campaign will send within minutes (if within the sending window).
8. Follow-Ups not yet due
Status: On hold – Waiting for follow-ups
Why it happens: The follow-up delay you set hasn’t passed yet.
Fix:
No action needed. Follow-ups send exactly after the delay set in Content (e.g., “2 days after previous email”) and within your sending window.
Example: If the first email is sent June 26 at 3:45 PM with a 2-day delay, the follow-up will send June 28 at 3:45 PM, even if your window starts earlier.
⏳Follow-up emails are sent based on the delay (in days) you set in the Content tab.
For example, if the first email was sent on June 26 at 3:45 PM and you scheduled a follow-up for 2 days later, the next email will be sent on June 28 at 3:45 PM, provided it falls within your sending window.
Even if your sending window starts earlier (e.g., 9 AM), follow-ups will always be sent exactly after the set number of full days from the previous email.
