SMS carrier throughputs for 10DLC campaigns
Zoom offers SMS across multiple countries, number types, and products. However, in the US and Canada, when a 10DLC number is used, carrier-imposed campaign volume tier restrictions come into play and influence your overall messaging throughput.
How to understand 10DLC campaign volume options
Zoom supports two tiers of volume for 10DLC Campaigns: low-volume and high-volume SMS campaigns. Carriers have specifically defined these campaign types for UCaaS providers such as Zoom.
When creating a 10DLC campaign with Zoom, the default campaign provisioned is a high-volume campaign. Customers also have the option to provision a low-volume campaign, which is included at no cost. However, a low-volume campaign has limited throughput and is only recommended if your SMS usage is low.
- High-volume campaigns are provisioned with the default throughput. If you want to increase your throughput on a high-volume campaign, you will need to undergo a process called Brand Vetting with the campaign registry, which requires an additional one-time vetting fee.
- Low-volume campaigns are not eligible for throughput increases. If you have a low-volume campaign and you are running into throughput limitations, Zoom recommends you create a high-volume campaign and also undergo brand vetting if the default throughput is not sufficient.
