Overview of Benefits 

Going to SPAM is one of the many pain points faced by online businesses. It is important to understand the reason behind this and provide better user experiences. SmartSender does just this by providing express or detailed deliverability audit to bring out the main issues, mistakes and shortcomings and suggesting fast and efficient solutions and further 24.7 monitoring of your campaigns. 

Leverage advanced user behavioral insights to segment users so you can deliver timely personalized user engagement experiences to prospects and customers. Personalization has helped increase click-throughs for a number of marketing campaigns designed by our customers. Our customers increase their customer engagement by 10%-200% by sending personalized offers on the category of product their users viewed and the time of the day the segment was most active on the website via SmartSender’s push notifications.

Our web-tracking system uses browsing behavior and helps target people who meet specific criteria e.g. female customers who watched your hip shaping fitness exercises four times during a week. This means virtually unlimited targeting opportunities, thanks to the variety of available options. SmartSender makes it easier for marketers to use existing segments to create upselling and cross-selling campaigns which actually convert. The ROI-based reporting relies on actual transactions and allows marketers to clearly see performance of their marketing campaigns across multiple channels.
