Here's a list of the most common reasons why your campaign is not sending:
Reason 1: The campaign is paused or completed
• If a campaign is paused, it won’t resume sending emails automatically (this may be due to a manual pause you made). To restart email sending, you’ll need to activate it again.
• If a campaign is completed, all emails have already been sent. It becomes an evergreen campaign, meaning that if you add new recipients, it will automatically start sending emails to them.
Reason 2: Not within the sending window
📌 Why it happens: The campaign is currently outside the designated sending window.
ℹ️ Associated campaign status: On hold - Outside of sending window
✅ Fix: You can adjust the sending window in the campaign Settings tab.
💡 Keep in mind that if other campaigns are currently sending from the same email account, they will take priority over your latest campaign once the sending window is adjusted.
Reason 3: Email account has reached the daily sending limit
📌 Why it happens: The email account used to send emails has hit the daily sending limit.
ℹ️ Associated campaign status: On hold - Waiting for sending limit reset
✅ Fix: Go to Email Accounts Settings and edit the daily sending limit (recommended: 15 emails p/day for new connected accounts). If you choose not to increase the sending limit, you can wait for it to reset, and emails will be sent automatically.
🕒 The daily sending limit resets at midnight (00:00 AM) based on the account’s time zone.
Reason 4: The email campaign is preparing
📌 Why it happens: A new email campaign typically takes a few minutes to schedule all emails. During this time, no emails will be sent, and the campaign will remain in a preparing status.
ℹ️ Associated campaign status: Preparing
✅ Fix: No action is required, the campaign will automatically activate once all emails are prepared.
Reason 5: Sending accounts error
📌 Why it happens: One or more sending accounts are disconnected.
ℹ️ Associated campaign status: Error - One or more email accounts have been disconnected
✅ Fix:
• Go to the Email Accounts settings and use the Reconnect link to reconnect the disconnected email account
• Follow the account reconnection steps to resolve any issues.
• Once the affected account(s) are reconnected, the campaign status will update automatically.
Reason 6: No email account(s) associated with the campaign
📌 Why it happens: A sender email account hasn't been set for the email campaign
ℹ️ Associated campaign status: Error - This campaign has no email accounts
✅ Fix:
Click on the email campaign and choose one or multiple existing email accounts or connect new ones in the From section.
Once the email account(s) are selected, the email campaign will automatically resume unless it was manually paused.
Reason 7: Other campaigns take priority over the new campaign
📌 Why it happens: Other campaigns sent from the same email account(s) were created before the current campaign and have priority over the new campaign
ℹ️ Associated campaign status: On hold - Waiting for other campaigns
✅ Fix: To prioritize a campaign, pause other active ones using the same email accounts. Once paused, the new campaign will start sending emails within a few minutes if it’s within the sending window and no other factors prevent it.
Reason 8: Follow-ups aren't scheduled to be sent now
📌 Why it happens: It's not yet time to send follow-up emails.
ℹ️ Associated campaign status: On hold - Waiting for follow-ups
✅ Fix: No action is required, the campaign will automatically activate once it's time to send follow-up emails.
⏳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.
