Updated August 2026. MessageMedia is now Sinch Engage. The platform rebranded on 28 July 2026 and the Australian and New Zealand
messagemedia.comsite was retired on 1 September 2026. Sinch says products, APIs, pricing, contracts and the local support team are unchanged. This review covers the service as it stands after that change.
Provider Overview
MessageMedia is one of Australia’s largest SMS providers, and for years was the brand behind a lot of other providers, having acquired several smaller companies and run them as sub-brands.
They were founded in 2001 and are headquartered in Melbourne, Australia. With that long in the business they’ve developed a large suite of tools and a mature product offering.
Ownership: part of Sinch
MessageMedia was acquired by Swedish communications group Sinch in a deal announced in June 2021 and completed in 2022. That matters for two reasons.
First, MessageMedia is no longer an independent Australian provider. The local team and support remain, but the product roadmap belongs to a global parent.
Second, several providers you might compare it against are now siblings, not competitors. MessageMedia acquired ClickSend in 2019 and SimpleTexting separately, and all of them came under Sinch. If you are running a competitive tender between MessageMedia and ClickSend, you are negotiating with two brands owned by the same company.
The Sinch Engage migration
In 2026 Sinch folded MessageMedia into its unified platform. From 28 July 2026 the product is Sinch Engage, with new branding throughout the app and support site. Existing credentials still work. Contacts, templates, campaigns and account history stayed in place (there was no data migration) and Sinch has been explicit that API connections and integrations are not affected, so existing integrations keep running unchanged.
The AU/NZ messagemedia.com website was retired on 1 September 2026.
Notably, ClickSend has not been moved onto the unified platform. It now carries Sinch branding too (the product is “Sinch ClickSend”) but it still runs on its own domain with its own dashboard, API and pricing, and its website has not been retired. If platform stability matters to you, that is a live difference between the two Sinch-owned options today.
Uptime and SLA
MessageMedia offers a robust API backed by a high speed gateway that can deliver over 500 messages per second (though default rate limits are much lower). With these high message volumes other providers back up, however Message Media is able to deliver millions of messages per month for single customers.
They also offer industry leading uptime and low API latency, with almost all (95%) of messages delivered in under two seconds to the carrier. Customers sending high volumes are able to request custom SLAs.
MessageMedia is used by many of Australia’s largest public traded companies, including NAB, Commonwealth Bank, Rebel, 13cabs and more.
Support
MessageMedia has 24/7 support, backed by local Australia teams during the Australian working hours and overseas teams outside local hours.
These teams are able to assist with both technical and billing/account issue, and are some of the best in the industry. We’ve had tickets resolved in under 10 minutes, even for complex issues that required specific domain knowledge.
Will MessageMedia work for your SMS needs?
For Large Organisations
MessageMedia is probably your best choice as a large business, as they have an emphasis on security and support, as well as dedicated account managers that can assist whenever required. You’ll be in good company, with many of Australia’s other ASX200 businesses also utilizing them for their SMS needs.
When you want to integrate with your own software, MessageMedia has dedicated integration teams that can assist your development teams, however this comes at additional cost that needs to be discussed with your account manager.
MessageMedia also uses high quality routes, while more expensive that some cheaper providers, has considerably better deliverabilty and is backed by a 100% delivery guarantees.
Messages are accepted by API, the web interface, SMPP or can be handled by your account manager.
For SME and Small Business
MessageMedia caters best for larger businesses, as their messaging rates are considerably higher that other providers when sending smaller quantities of messages (under 1 million per month).
This means you’ll be paying considerably more for messaging, but you are getting the high quality service and support that you’d expect at that price.
They don’t charge a monthly fee for their prepaid, but there are minimum volume commitments to receive lower SMS pricing that the standard rates.
Most features offered for free by other providers are gated behind high plans, which cost up to $699 per month (though, they do include some bundled SMS credits)
Pricing
MessageMedia runs a monthly plan model rather than pure pay-as-you-go, with effective per-message rates falling as you move up plans. Recent market comparisons put plans in the roughly $45–$789 per month range with effective rates around 5.9c on higher tiers, against a prepaid rate closer to 8c, among the more expensive in the Australian market.
Compare that to ClickSend, which is Sinch-owned as well but has no subscription: 7.2c per SMS at the entry tier down to 5.7c at $10,000 top-ups. If you send irregularly, the no-commitment model often wins even at a higher headline rate; if you send consistently, the plan model can be cheaper.
Sinch Engage publishes plan pricing for Australia, so you can work out a monthly cost without talking to sales:
Larger volumes are negotiated, so treat the top plan as a starting point rather than a ceiling. For a sense of the gap, touchSMS charges a flat 5c with no plan fee, which is below the Advanced plan’s effective rate before any subscription is paid.
APIs and Integrations
Messagemedia offers a variety of APIs and integrations covering most SMS use cases, though some of these required higher subscription plans or a minimum spend.
SMS API
MessageMedia offers a robust and secure API supporting most of the features available on the website. Their API documentation is well written and comprehensive, covering both SMS and MMS. Note that developer resources moved under Sinch with the 2026 rebrand, though the API endpoints themselves are unchanged.
The MessageMedia rest API offers the following features
- HLR Lookup API
