ZapBounce and GoHighLevel
GoHighLevel is built for agencies running many client sub-accounts, often on shared sending infrastructure. That architecture creates the specific risk this page is about.
One client's unverified import can damage the deliverability of every other client on the same infrastructure, and those clients will never know why their campaigns declined.
Shared infrastructure means shared damage
Where sub-accounts share a sending domain or IP reputation, the bounces from one client's list are attributed to infrastructure the others depend on.
The agency then has ten clients whose results dropped in the same month, for a reason that lives in an eleventh client's contact import.
Diagnosing that after the fact is slow, because each client's own metrics look like an individual problem rather than a shared cause.
How the data moves
Verify every client import before it lands
Make it a step in onboarding rather than a service you offer. The risk is to the agency, not to the client.
Store the verdict as a custom field per sub-account
So each client's workflows can filter on it without agency intervention.
Use separate sending domains per client where the plan allows
That contains the damage when a verification step is skipped, which eventually it will be.
Report list quality per sub-account
An agency-level view of which clients carry the worst data is what lets you intervene before a send.
Setting it up
- Add verification to the client onboarding checklist, before any import.
- Create a custom contact field for the verdict in each sub-account.
- Verify each client list as its own batch, named after the sub-account.
- Add a workflow condition so sends only reach contacts with a valid verdict.
- Use separate sending domains per client where your plan supports it.
- Build an agency-level report of invalid rate per sub-account.
GoHighLevel: common questions
Why does one client's list affect the others?
Because sub-accounts often share sending infrastructure. The bounces attach to the shared reputation, not to the client who caused them.
Should each client have their own sending domain?
Where the plan allows it, yes. It is the only real containment when a verification step is eventually skipped.
Can I stop clients importing directly?
Through sub-account permissions. The alternative is discovering an unverified import after the send.
