Is the ReCharge checkout flow separate from Shopify?
Yes. Even if you already have a Shopify transactional message opt-in configured, you’ll still need to go through the gist setup process again for ReCharge.
What happens if a customer opts-in to transactional messages but doesn’t provide their phone number?
The customer won't be opted-in to transactional messages, and won't receive a message about their order. While this may cause some customers to not opt-in who otherwise intended to, this'll prevent any interruptions to your checkout flow in Shopify.
What happens if a customer orders something during quiet hours?
If a customer triggers a ReCharge journey during quiet hours, they'll receive messages from that journey immediately. All transactional journeys ignore quiet hours. For more, see Quiet hours.
What happens if a customer who opted-in to transactional messages only also opts-in to promotional messages?
The subscriber will receive order updates after they make a purchase, and will receive promotional messages when you schedule a campaign or if the subscriber qualifies for a triggered message.
The subscriber will always receive their transactional message, even if they’ve received a promotional message recently.
If a customer is subscribed to both promotional and transactional messages, what happens if they opt-out from transactional messages?
Customers who opt-out of transactional messages are automatically opted-out of both types of messages. Note that the opt-out rate for transactional messages is very low (~0.33%).
