Problem Statement

The Customer was struggling to send notifications to different user segments. This included sending in-app/push notifications and web notifications to users who might be interested in specific brands/offers. In order to increase revenue a need arose for sending personalised notifications to less engaged users. Due to this, the requirement to send push notifications to end users on mobile and the web came to the forefront.

However, creating a communication platform to send out notifications via the web and mobile was a time-consuming and expensive affair. Also, for mobile users, the platform would need to offer separate solutions for both iOS and Android users.

So, to remove these challenges, Arrk recommended the implementation of a one-stop communication platform that would send out emails, in-app/web messages and SMS notifications to users at a minimal cost. The platform that Arrk suggested was OneSignal.

Arrk designed, developed, and implemented an integration between our client’s core systems and OneSignal to improve their notification game without incurring significant costs.

Solution Development

In a strategic move to improve analytics, Arrk proposed OneSignal as the best communications platform for OneVoice. By collaborating closely with the SAAS platform, Arrk deepened its understanding of its integration methods and APIs. This resulted in a seamless integration of back-end systems with OneSignal that empowered the client with easy customer communications. However, this did not stop there; Arrk took charge of crafting the dynamic templates for push notifications and in-app messages in the OneSignal platform itself to ensure a unified user experience.

The final touch of using the tool was a smooth migration of data from our client to OneSignal to make an efficient transition.
