Notifications types and triggers

Notifications the we support fall into 2 categories: in-product announcement and alert and external like email. These notifications and their associated triggers are designed to work in conjunction your existing product engagement touch points in a seamless way.

Email

Emails are a way to keep your users aware and engage with the referral program without them needing to log into the application. By default, Cello will send emails about the key events in the referral lifecycle. Standard email template examples

Activation campaign

In addition to the default notification journey, you can run an activation campaign with Cello to activate users for your referral program with recurring announcements. Default activation campaign sequence How it works:
  1. Activation campaign starts 30 days after “New referrer activation” announcement is sent and the user has not acted on it.
  2. The recurring announcements will be only send if the user full-fills a certain activity pattern in the product like:
  • Referrer has used the app at least once after reading the last announcement.
  • Last activation announcement was read.
  • Referrer didn’t share in the last 30 days.
