Send SMS without strings attached — Australia's cheapest self-serve bulk SMS, no fixed-term contracts.
SMS Broadcast is an Australian bulk SMS service that has provided businesses with quality, cost-efficient SMS solutions since 2005, built around a simple promise: "send SMS without strings attached." The platform is positioned as a low-cost, self-managed alternative to sales-led messaging platforms — customers buy prepaid credits (from 3.7c per SMS with up to 40% off on first purchase) rather than committing to fixed-term contracts or monthly fees, with credits valid for 12 months. SMS Broadcast markets itself as "the cheapest in Australia," achieving this by stripping out salesperson involvement and offering a purely self-serve model: an online SMS web app, Email-to-SMS, and a developer HTTP/email API included at no extra charge, plus templates, message history, scheduled sending, contact list imports and dedicated numbers. It claims onshore connections with Telstra, Optus and Vodafone for local delivery reliability, and reports being trusted by over 30,000 Australian businesses across industries such as retail, education and finance, with a 4.7–4.8 out of 5 rating from more than 5,000 Reviews.io reviews. SMS Broadcast was acquired by MessageMedia in 2018 and is today operated as a brand of Sinch (following Sinch's 2021 acquisition of MessageMedia and MessageMedia's 2026 rebrand to Sinch Engage) — its own SMS Broadcast Pty Ltd legal entity was wound up in early 2026, with its Terms of Service, contracting entity and support infrastructure now folded into Sinch Pty Ltd, while the SMS Broadcast product brand continues to operate as a distinct, budget-tier self-serve offering within Sinch's Australian portfolio alongside Sinch Engage (MessageMedia) and ClickSend.
