Wholesale rate, carrier pass-through and our margin billed as three separate lines. Registered 10DLC from day one.
Carrier pass-through is a blended $0.0042, weighted across AT&T, T-Mobile and Verizon. It is set by the carriers, it rose four times in 2026, and nobody earns a cent on it. We bill it at cost and show you the receipt.
A toll-free number runs at 3 messages per second. That is the constraint behind every “blast” product that never registered a 10DLC brand, and it does not go away by buying more numbers.
AT&T rate limits per campaign, T-Mobile caps daily volume per brand across every campaign that brand owns. Spreading a list over extra numbers to get around either one is snowshoeing, and carriers filter it. Times use the binding constraint in each case.
Five tiers, published, applied automatically. No call, no commitment, no minimum. Move the sliders and check our arithmetic.
Marketing copy averages 1.3 to 1.6 segments a message. One emoji doubles it.
Both columns use the same volume and the same carrier pass-through. Ours is itemized on the invoice, theirs is folded into one rate. Numbers are billed at $4.00 against their $5.00, MMS at $0.038 against their $0.045.
Registration, routing, replies and the parts that keep a brand out of trouble.
Brand registration, campaign registration and third party vetting through The Campaign Registry, handled at signup. Vetting costs $41.50 and we absorb it, because an unvetted brand is capped at 10,000 messages a day.
Two-way threads, keyword automations and org-wide opt-out propagation. A STOP on any list suppresses that number everywhere, immediately.
25x
A vetted 10DLC brand clears 100,000 recipients in about six minutes. The same list on a 3 MPS toll-free number takes 9.3 hours.
Qualifies leads, books calls and escalates to a human on its own. $59 a month, usage included, and no charge to configure it.
Power dial the replies that came back warm. $0.029 a minute, recording and transcription included, nothing monthly to unlock it.
Traffic is dual-homed across two tier-one providers. When delivery to one carrier starts degrading we reroute mid-campaign, before you notice. A rate governor keeps each brand inside its real AT&T throughput limit and its T-Mobile daily cap, so a campaign queues honestly instead of getting filtered.
“the pass-through fees have no impact on our gross profit”
Carrier surcharges are revenue at exactly zero margin. Every platform collects them and every platform passes them straight to the carriers. The only real question is whether your invoice admits it.
Four in eleven months
A platform holding $0.0025 of spread on a $0.015 flat rate cannot absorb many more of these. Ours is indexed, so a carrier increase moves one line and not the price of the product.
