Sinch Engage
A business messaging platform for SMS, WhatsApp, and RCS, built for conversion
About Sinch Engage
Sinch Engage (formerly MessageMedia) is Sinch's self-serve business messaging platform for sending SMS, MMS, RCS, and WhatsApp campaigns, automated notifications, and two-way conversations from one shared inbox. It connects natively to HubSpot, Salesforce, Shopify, NetSuite, Zoho CRM, Microsoft Dynamics, and Epic, so teams can trigger reminders and campaigns from the systems they already use.
Pros & Cons
Pros
- Covers SMS, MMS, RCS, WhatsApp, Messenger, and Instagram from one platform and one team inbox
- Deep native integrations with HubSpot, Salesforce, NetSuite, Shopify, and Epic, which many SMS-only tools lack
- Backed by Sinch's own carrier infrastructure, with 24/7 live chat and email support on every plan
- Unlimited contacts and a free dedicated number on all plans
- 14-day free trial with no credit card required
- Reviewers report fast support response and straightforward setup
Cons
- Entry price of $99/month is high compared with SMS tools that start under $30
- User seats are capped at 1 to 3 per plan; extra users cost $25 each
- RCS and SSO are reserved for the $799/month Pro plan and above
- Pricing and feature availability vary by country, so non-US buyers need to check their regional page
- Recent rebrand from MessageMedia means reviews and docs are split across old and new product names
