Open campaign Settings
In the campaign builder, go to the Settings tab and find the Contact Engagement section.
Enable auto-pause
Tick Auto-pause unengaged contacts.
Set the threshold
In Unengaged emails before pause, enter how many consecutive cold emails to allow before pausing (minimum 1; the field defaults to 3 if left blank).

Understand 'unengaged'
A contact is considered cold once they've had N consecutive emails with no opens, clicks, or replies.
Know it needs manual resume
“Paused contacts stay paused until manually resumed.” They don't restart on their own.
Track paused contacts
Paused contacts still read as Active on their Inbox row, but the conversation shows a Paused journey card.
Pro tips
Match the threshold to your sequence length
Pausing after 3 cold emails on a 5-step sequence saves the last two sends on contacts who'll never engage.
Not the same as delivery-protection auto-pause
This is engagement-based auto-pause, separate from the setting that watches bounce/spam rates: you can run both.
Manual resume is intentional
It forces a human decision on whether a cold contact is worth re-approaching, rather than silently retrying forever.
A rising pause count is a list-quality signal
Growing cold segments usually need better targeting or cleaning: not more emails.
Frequently asked questions
Where is auto-pause?
Campaign Settings → Contact Engagement, the “Auto-pause unengaged contacts” checkbox.
What counts as unengaged?
N consecutive emails with no opens, clicks, or replies: you set N.
What's the minimum threshold?
1. The field defaults to 3 if left blank.
Do paused contacts resume automatically?
No: they stay paused until you manually resume them.
Is this the same as delivery-protection auto-pause?
No. This pauses individual cold contacts based on engagement; delivery protection pauses on bounce/spam-rate thresholds.
Where do I see paused contacts?
In the Inbox they still show as Active, but the conversation shows a Paused journey card.
