Actions allow you to define what your funnel will do next, when it will be done, and for who.
Delay the funnel
Delay sending this message for a specific amount of time after sending the last message.
This is a great feature for creating funnels since we want to stay connected but we do not want to annoy our audience with too many text messages.
* It is important to note that the delay time will be calculated from the time the last action was triggered.
Add tag to subscriber
Your customer will be tagged in your Shopify application and in our local subscribers list.
Send SMS or MMS
This is the most anticipated feature of the funnel builder.... sending a SMS message or a MMS. It's simple. Just provide your message.
