Reduce no-shows with reminders

Increase conversion with notifications

Products on your website may sometimes run out. You can easily notify your interested customers when the products are available again. Include the URL of the product to simplify the search for them and boost conversion directly.

Alert your employees of incidents and events

You monitor your crucial operating systems continuously. Your employees need to act if unexpected events occur. You can alert your employees proactively by SMS when your systems show irregular performance.

How it works
