10DLC Carrier Throughputs and Daily Limits

AT&T 10DLC Message Class

The message class is the means by which AT&T designates trust levels for brands based on their use-cases and content. AT&T applies limits based on campaign type, and throughput is measured per-SMS-segment per-minute at the campaign level, meaning that all numbers in a campaign share the allotted throughput. Verified brands can have access to all standard Use Cases with message classes E and F. Russell 3000 brands have access to message classes A and B.

Note: throughput and SPAM enforcement to classes G, N and Y are at the number level rather than the campaign level.

Note that less trusted senders are subjected to more rigorous anti-SPAM policies than those with a higher level of trust. Changes to message class can be requested.

T-Mobile Daily Outbound Message Buckets

The following T-Mobile chart shows T-Mobile’s message tiers and a brand’s associated daily outbound message limit. By default, a brand with a Verified TCR status falls in the “low message tier.” The exception to that are Brands on the Russell 3000 Index, in which case the top message tier is assigned. Brands have the potential to move to a higher tier by applying for third-party vetting, which would result in a brand vetting score relative to a T-Mobile message tier.

The daily limit sets a total number of outbound SMS segments and MMS messages that a registered A2P brand entity can send to T-Mobile subscribers per day. This reflects the peak limit on any single day and is not to be confused with a daily average. This limit is applied at the brand EIN (Employer Identification Number / tax ID) level and is shared across not only all campaign use cases under a single brandID, but across all brandIDs sharing a single EIN.

The limit is based on a brand’s:

• External vetting score
• Default score (if no external vetting has been requested)
• Russell 3000 Index status (which - if applicable - automatically enables the highest sending tier for the brand)

For example, if a brand has a vetting score of 70, the brand falls in the “40,000 outbound message segments per day” tier. If that brand has two registered brandIDs - each on a different provider - and each of those brandIDs has four registered campaigns, those 40,000 outbound messages are shared across all eight campaigns within a twenty-four-hour period.

Additionally, note:

• The twenty-four-hour period begins at midnight (12:00 am) PST and ends at 11:59pm PST.
• Messages exceeding one segment in length will count toward the limit based on the total number of segments. (e.g. a 200-character transaction which is split into two segments will count as two messages from the total daily limit.)
• For brands who exceed their daily limit, additional messages sent within the twenty-four-hour period will be subject to blocking.
• Convey does not have visibility to messages sent or campaigns registered with other providers.
• Brands wishing to send more than 200,000 messages per day should consider short code or toll-free numbers.

If your expected required range is higher than any of the above range options, please submit for Special Business Review (Messaging Volume Exception).
