INDUSTRIES For business messaging
“We’d been using email marketing for a long time, and we were posting to social every day, but we weren’t seeing those cut-through and open rates that we were looking for. With the support of Sinch, we targeted our highly engaged audience first with SMS for Black Friday…and it paid off.
“Email is great, but being able to message people directly is such an easier way of communicating with those customers. Using the platform and being able to deal directly with people, that’s super powerful for us, and it works really, really well.“
“Sinch Engage is really easy to use. We import our customers through our email provider or through Shopify, then we’ll write up the SMS campaign, pop in any personalized fields such as their name and then schedule – it’s as easy as that.”
“Our reps had their own phones with their own messages on them. There wasn’t team visibility around how communications were happening, or where or when, and there was no automation, either. Now with Sinch, just having that cut-through and trust, and having a platform that knows how to handle these things has really helped us. It’s been an awesome experience for our business.”
Frequently asked questions
What the change means for you.
Yes. After more than 20 years serving businesses across Australia and New Zealand, MessageMedia is now Sinch Engage, the same messaging platform for SMS, MMS and WhatsApp, with the same local team behind it. Same platform, same people, new name and look. If you came here looking for MessageMedia, you’re in the right place.
No. Your account, contacts, templates, and campaigns are already in the Sinch Engage app, exactly as you left them. There’s nothing to reconfigure. You may be asked to set up multi-factor authentication the next time you log in, which takes about two minutes.
Very little day to day. You keep the same platform and the same local team, now backed by Sinch’s global network. What’s actually different is a handful of URLs: you now log in at app.sinch.com/login with your existing email and password. Your help centre has moved to support.app.sinch.com and platform status to status.sinch.com.
Yes. New signups go through Sinch Engage now. It’s the same platform Australian businesses have trusted for two decades, so you can start a free trial or book a demo whenever you’re ready.
No. The rebrand doesn’t affect your contract terms, pricing, or billing cycle, and your API connections and integrations aren’t impacted either. If you’re in Australia or New Zealand, you’ll see the legal entity on your invoices change from Message4U Pty Ltd to Sinch Pty Ltd. That’s a name change only. Your ABN and all other account details stay the same.
