Twilio removed the published SMS volume-discount ladder from its US pricing page
The Automatic SMS Volume Discounts tables and their jump-to nav entry disappeared from twilio.com/en-us/sms/pricing/us between 1 March and 10 April 2026. Automatic volume pricing still exists but the thresholds and rates are no longer published.
The US SMS pricing page carried a 'Volume discounts' jump-to link and two Automatic SMS Volume Discounts tables — one for long code and toll-free, one for short code — publishing six tiers from the first 150,000 messages a month down to above 1 million, at $0.0083 / $0.0081 / $0.0079 / $0.0077 / $0.0075 / $0.0073 per segment outbound and inbound.
No volume table anywhere on the page and no 'Volume discounts' entry in the jump-to nav. The page retains the sentence 'Our pay-as-you-go pricing gives you control over your messaging costs, with discounts as you scale' and a Committed-use discounts block reading 'Enterprise pricing is available to customers with use cases that exceed our volume discounts... Contact our sales team to learn more.'
Twilio had published its automatic SMS volume ladder continuously since at least January 2016. The 2016 version listed seven tiers running from $0.0075 on the first 5 million messages a month down to $0.0005 above 1 billion. The May 2023 page rebuild shortened that to six tiers from 150,000 to 1,000,001+ messages, bottoming at $0.0069. In June 2025 the whole ladder rebased $0.0004 higher with the SMS list-price rise.
Between the 1 March 2026 and 10 April 2026 archived snapshots the section disappeared entirely — the tables, the heading and the nav anchor. Nothing on the page marks the removal.
The mechanic itself is unchanged. Twilio’s help centre article “How Volume Pricing works at Twilio” still states that Twilio “automatically discounts the price you pay as your project hits monthly volume thresholds” on US and Canadian voice minutes, messages and phone numbers, and still gives worked examples for voice (inbound falling from $0.0085 to $0.0080 after 500,000 minutes) and for phone numbers (a local number falling from $1.15 to $0.575 after the 1,000th number is charged). What has gone is the buyer’s ability to compute a marginal messaging rate without contacting sales.
AT&T’s long-code carrier fee also rose in the same window, from $0.003 to $0.0035 per outbound SMS segment and from $0.0075 to $0.009 per MMS.
The Automatic SMS Volume Discounts section is gone from the US messaging pricing page, along with its entry in the jump-to nav. The page keeps the sentence 'with discounts as you scale' and a committed-use 'Contact sales' block but no longer says at what volume the rate changes or to what. The 1 March 2026 snapshot still published the full ladder. AT&T's long-code carrier fee rises from $0.003 to $0.0035 per outbound SMS segment and $0.0075 to $0.009 per MMS in the same window.
