Campaign Delivery Engine
The delivery engine controls how PING8 sends the campaign.
Options
| Option | Use when |
|---|---|
| Local Postfix | Low-volume local testing or fallback. |
| KumoMTA | This campaign must explicitly use KumoMTA. |
| Tenant default | Operators have configured the tenant default route. |
Recommended setting
Use Tenant default for normal production campaigns once the tenant delivery profile is tested.
Sending profile
When using KumoMTA or Tenant default, PING8 may show a sending profile field.
- Choose
Autofor tenant-selected profile. - Choose a named profile for an intentional pool/source route.
If no profile is ready, do not launch production sends.
Threads
Use Auto for most campaigns. Custom threads should be used only by operators who understand server capacity and provider throttling.
