| Their stated threshold | ConvertKit's guidance targets bounce rates under 2% and their creator-focused deliverability advice emphasises removing cold subscribers before they become a problem. |
| What happens if you cross it | ConvertKit reviews accounts with poor list quality and can restrict sending. Their model leans on education and their built-in cold subscriber tooling more than on abrupt enforcement. |
| Where the bounce data lives | Subscribers filtered to a bounced state, and the broadcast report's bounce count. ConvertKit surfaces cold subscribers as a specific filter, which is more actionable than a bounce number. |
| How bounces are classified | ConvertKit marks a subscriber as bounced at the subscriber level, which removes them from every sequence and broadcast at once rather than from one list. |
Bringing the rate down
Each step is an action inside ConvertKit, in the order worth taking them.
Use the cold subscriber filter first
ConvertKit can show subscribers who have not opened anything in a defined period. Removing them lifts engagement and reduces the pool of addresses that will eventually bounce.
Check which form or landing page they came from
Every subscriber carries the form that created them. Bounces concentrated on one lead magnet name the problem instantly.
Audit your sequences for old triggers
A subscriber can enter a sequence months after signup. A bad import keeps generating bounces through automation long after the broadcast that revealed it.
Turn on double opt-in for lead magnets
Free downloads attract fake addresses. Requiring confirmation before delivering the file removes almost all of them.
Verify a list before importing it from another platform
Creators migrating from another tool bring years of accumulated addresses. That decay arrives on the first broadcast.
The mistake people make here
A bounce report mixes two causes that need opposite responses: addresses that do not exist, and receivers refusing mail they could have delivered. The first is fixed by checking the list. The second is a sending problem and no amount of cleaning will move it.
Questions people ask
What is a cold subscriber in ConvertKit?
Someone who has not opened or clicked in a period you define. It is an engagement state rather than a delivery one, and ConvertKit surfaces it because engagement is what mailbox providers weigh.
Does removing cold subscribers fix bounces?
Partly. There is overlap between abandoned and undeliverable, and plenty of cold subscribers have working mailboxes they simply ignore. It helps reputation more than it helps the bounce count.
Do bounced subscribers count toward my plan?
Removing them reduces your subscriber count and therefore your tier, which is the direct saving from list hygiene here.
