Lowawot Alice - PeerSpot reviewer
Marketing Director at UPS
Targeted push campaigns have increased conversions and are driving more repeat customer purchases
OneSignal has positively impacted my organization by allowing us to reduce our cost of customer acquisition and increase our conversion rate from 40 to 65%. We have also increased our conversion rate to 30%. Additionally, OneSignal has allowed us to grow our number of subscribers organically, driving more website traffic and increasing sales engagement and campaigns from 50% to 65%. Since we are able to send more push notifications to our subscribers on their preferred device, we can reach out to them and they can see what we offer as services, enabling them to subscribe to our platform. This allows us to drive more website traffic, increase sales, enhance sales engagement, and drive more productivity. OneSignal offers the best features, including sending instant notifications without delay, providing all necessary features for testing, being highly cost-effective, handling huge volume efficiently, and providing great customer support.
AmandaSanchez - PeerSpot reviewer
Consultant and Startup Founder at AimHi Enterprises
Macros and automation have streamlined workflows and reduced manual effort across support teams
The ability to communicate on the Zendesk ticket through the actual user software, so TOPs, would have been helpful. Somehow seeing a user's ticket history within our app would have been beneficial. That is the only thing that I do not think existed at the time that might have been helpful. Some people struggled with Zendesk, but it was always easy enough to show them how to use it and what they were missing. The only times we really had people report concerns about it was when they did not understand that it could do that or how to use it in that way.
