Easy to set up and use and great support

We have been using SMS for Salesforce by Sinch Engage for a couple of years and it works very well. It is easy to set up and use and their support is great when you do need help. We extended SMS to use RCS and WhatsApp and they had good documentation but were also on hand to assist. I thoroughly recommend this app and company.

Hi Judith - thanks for the 5-star review! We're thrilled to hear SMS for Salesforce has been working well for you over the years and that setup and day-to-day use have been smooth. It’s great to know you’ve expanded into RCS and WhatsApp, and that both the documentation and support team were there when you needed them. We really appreciate the recommendation - and your continued trust in Sinch! - Sinch Team

Great Customer Support

I’ve only been using MercurySMS for a short time, but I’m already impressed. The app is solid, and the customer service is absolutely fantastic. The support team is incredibly responsive, and any ideas or limitations I’ve mentioned are genuinely listened to by both support and development. It’s rare to find a company this engaged with its users.

Excellent App & Great Support

We're using the app since 2022 and are very happy with it. The app is very easy to use and have lots of features that can be utilized for your business needs. The technical support team I worked with Lorenzo Ocampo and Calliope Bradshaw are highly technical and skillful. I highly recommend the app.

Speedy and helpful support team

We’ve been trialling this app and are now ready to roll it out across our team. Before launch, we had a few custom scenarios to work through and needed support from MessageMedia/Sinch. Their team has been punctual, friendly, and incredibly helpful with every question and request. We feel confident moving forward knowing we’re fully supported, and that the system is flexible enough to adapt to our business needs.

Best Customer Support Ever!

This is a new app for our company and Sinch was there to help up us move forward, connecting Prod and Sandbox environments for testing, educating us about the platform & how to trouble shoot. I highly recommend this easy to use messaging system.

Great app and super support

Glad you liked it! MessageMedia Team

Easy Setup, Fantastic customer service

Message Media provided us with significant support during our onboarding. Setup involved following a simple How To Guide and for any areas where I needed help or was less confident/unsure, their Customer Service proved to be very knowledgeable and accessible. The app does exactly what we need it to do and I was easily able to search for any new features that I wanted to implement. As a new customer to Message Media, I’ve been impressed by the experience to date with both our Account Manager and Customer Service providing some of the best support that I’ve seen.

Terrible install, worse to uninstall

Such a discouraging experience. It took days to install the app and now it seems to be hijacking our contact records with some stack error. Uninstall is not straightforward either. I would not recommend Mercury SMS.

Hi Ray, sorry to hear you had issues with our app - a stack error usually occurs if the app has not been completely set up. You'll be able to uninstall Mercury SMS by going to Setup > Installed Packages. Let me know if you'd like to discuss anything further, I'm more than happy to. - The MessageMedia team
