When you set it live you have the option to ‘back populate’ the flow and if you do so then customers will start to receive the welcome series as if it had been live when they signed up.

Thanks so much, Sean!

I just pushed it live and got this message: “Backpopulate FailedFlows with dynamic coupons can't be back-populated.”

Does that mean none of my customers who added their emails before I pushed it live will have the coupon? 

@ChrisEngland 
This might work for already existing customers before you created the flow. 

• Add all the customers who subscribed to list before the date the flow was created. 
• download the segment
• create new list
• clone your welcome series and use the new list as the trigger. 
• Make the flow the flow live and ready and then upload the people that you downloaded from the segment into the new list. 
  And boom!! they receive the welcome series emails. 

I hope this works. 

Yup, what @Edithola said.

@ChrisEngland another community member had the same situation about a year ago, below is a link to the thread, but it’s basically the same was what Edith mentioned:

Thank you, all!
