New Features

  • Rebrand to Sinch SMS for Salesforce

    Three years ago, MessageMedia joined forces with Sinch - a global leader in customer communications. This move helps us to bring even more meaningful conversations to life between businesses and their customers.  

    Since then, you’ve seen us evolve into Sinch MessageMedia, marking the start of an exciting journey.

    Now, we’re taking the next step: Mercury SMS is becoming Sinch SMS for Salesforce.

    You may have already noticed the new name and logo in the Salesforce AppExchange. In the coming weeks, you’ll see updates within the product experience as we complete the transition.

  • WhatsApp in the Message Feed

    We’re excited to announce that WhatsApp messaging is now available in the Sinch SMS Message Feed (formerly Mercury SMS). This update makes it even easier to connect with your customers using a new channel — all from within Salesforce.

    Until now, Sinch SMS supported SMS and MMS. With the addition of WhatsApp, you can now engage with users on your preferred channel - enhancing communication and fostering strong relationships.

    Key features include:

    • Seamless messaging: Send and receive WhatsApp messages directly in the Sinch SMS Message Feed - just like you do with SMS and MMS.
    • Quick replies: Receive and respond effortlessly to WhatsApp messages to ensure timely and meaningful conversations with a 24 hour window.
    • Message Initiation: Start new WhatsApp conversations directly from the Message Feed with approved templates.
    • Template Integration: Sync pre-approved templates from the Sinch platform straight into your Salesforce organisation.
    Note: You’ll need a WhatsApp Business account and access to the Sinch platform to use this feature. You'll also need to enable these remote sites:
