This guide covers the most common causes of campaign errors and how to resolve them.
You can use Instantly AI to investigate why the campaign is in error.
No Sending Accounts Assigned
To assign sending accounts to the campaign:
Go to the Settings section of the campaign
Check the 'Accounts to use' section
Select at least one active sending account
If you're using tags to assign accounts:
Verify that the correct tag is assigned to the campaign.
Go to the Email Accounts dashboard to ensure there are accounts under that tag
Confirm those accounts are active (not paused or in error)
After making changes, resume the campaign. It may take 10–15 minutes for updates to take effect.
No Sending Accounts Available
The campaign has sending accounts assigned, but they are not available to send emails. This can happen if accounts are disconnected, paused, reached their daily limit, or restricted by the campaign's slow ramp setting.
Check account daily limit:
Go to the Email Accounts dashboard
Review the Emails Sent column (Campaign emails sent today vs. Daily campaign limit). Verify if the account has reached the daily limit
Click on an email account → go to Settings. Make sure the Daily campaign limit is not set to 0
Check campaign slow ramp:
Go to the Email Accounts dashboard
Click on an email account → Open the Settings section
Scroll to locate Campaign slow ramp
Blue toggle = enabled
Grey toggle = disabled
When the campaign slow ramp is enabled for your email account, the sending starts low (2 campaign emails on day 1) and gradually increases by 2 per day until it reaches your daily campaign limit. This can cause campaigns to show no available accounts even when accounts are assigned to them.
Sending Accounts Disconnected or Paused
Sending accounts assigned to the campaign are either disconnected or paused, resulting in no active accounts available to send emails.
Go to the Email Accounts dashboard
Filter by "Status → Sending error/Has errors/Paused"
For accounts with errors: Follow the troubleshooting steps here
For accounts paused due to plan expiration: Accounts are automatically paused after the 14-day free trial or when your Outbound plan expires. To unpause accounts:
Subscribe to the Outbound plan on the billing page
Select the paused accounts in the Email Accounts dashboard (tick the checkbox next to each account)
Click the three dots (...) in the top right corner
Select "Unpause selected accounts"
Resume your campaign
High Bounce Rate
Instantly has automatically paused your campaign because recent emails have a high bounce rate (typically above 5%). This safeguard protects your email accounts and maintains deliverability.
Step 1: Verify Your Lead List
Run email verification on all leads before resuming the campaign. You can use Instantly's built-in verification or external verification tools.
Step 2: Review Your Email Copy
Remove any spam words
Send first email in plain text
Step 3: Investigate Bounce Reasons
Open the target Campaign
Navigate to the Analytics section of the campaign
Scroll down to locate the Bounces tab
Review bounce types (Hard, Soft, Unknown) and reasons
Review details for bounced leads
Click “View” to check the bounce reason
Step 4: Resume Your Campaign
After cleaning your list and addressing the bounce issues, resume the campaign. It won't be automatically paused again in the next 7 days, even if the bounce rate remains high.
If you'd like to turn off this protection entirely:
Go to Preferences
Find the Outreach Preferences section
Toggle off the 'Automatically pause campaigns with high bounce rates' option
Save changes
