Campaign Types and Throughput
10DLC Campaign Types & Throughput
What’s This About?
When sending SMS/MMS messages over 10-digit long codes (10DLC), your campaign type directly impacts message deliverability and volume. Carriers like T-Mobile and AT&T set throughput rules based on the use case type and vetting level.
This guide breaks down:
Campaign types (Standard vs. Low Volume)
Daily and per-minute throughput per carrier
How to increase limits via Trust Score
Carrier-specific notes
🧾 Standard vs. Low Volume vs. Special Campaigns
Standard Campaigns
These are the most common messaging types (e.g., 2FA, Marketing, Customer Care). They include a base daily segment allowance and per-minute throughput. You can boost throughput through "Additional Vetting" by companies like Aegis and WMC Global.
All Standard campaigns start with the same throughput limitations: 2,000 daily segments to T-Mobile, and 240 SMS/min and 150 MMS/min with AT&T.
So long as you’re not using a Low Volume Mixed campaign, you can increase your throughput via Standard Vetting (Read complete guide here). The score breakdowns are below:
Trust Score | T-Mobile Daily Segments | AT&T SMS/MMS per Minute |
|---|---|---|
1–24 | 2,000 | 240 / 150 |
25–49 | 10,000 | 240 / 150 |
50–74 | 40,000 | 2,400 / 1,200 |
75–100 | 200,000 | 4,500 / 2,400 |
Note: Verizon does not publish its throughput rates. T-Mobile’s limit is per brand, while AT&T's is per campaign.
Low Volume Campaigns
Low volume campaigns have the same use cases as standard campaigns, but are capped at 2,000 segments/day to T-Mobile and 75 SMS segments/min and 50 MMS/min with AT&T.
Special Campaigns
These are high-impact or regulated campaigns like political, emergency, or charity campaigns with different throughput structures. They may require manual review, tax exemption, or carrier approval.
Use Case | AT&T Segments/Min | T-Mobile Daily Segments |
|---|---|---|
Emergency | 4,500 (SMS) / 2,400 (MMS) | 2,000 |
Political | 4,500 / 2,400 | “Special” |
Charity | 2,400 / 1,200 | 2,000 |
Proxy / Agents | 60 / 50 | 2,000 |
K-12 Education | 720 / 50 | 2,000 |
Sole Proprietor | 15 / 50 | 100 |
Free Trials / UCaaS | Varies | Varies |
💡 Some special campaigns require carrier vetting, CSP approval, or IRS 501(c) verification. See CampaignVerify.org for political vetting.

TL;DR
Campaigns are categorized as Standard or Special
Daily & per-minute limits depend on trust score and campaign type
T-Mobile limits = by brand; AT&T = by campaign
Additional vetting can massively increase your throughput
Special campaigns (e.g., Political, Emergency) require more documentation but unlock higher volume
FAQs
Q: How do I improve my trust score?
