Hi @jadebiscuit, welcome to the community!

I’m not sure if you’ve already seen this, but a “Date Triggered” Flow might be exactly what you’re looking for.  The documentation to set one up is here:

• How to create a date property-triggered flow

So in your scenario, you would collect the date as a Custom Property, and then create three Flows:

• One that’s triggered 2 or 3 months before date
• One that’s triggered 5 or 6 months before date
• One that’s triggered 8 or 9 months before date

You can use some exclusions so that subscribers in the 1st Trimester don’t get the other two.  And those in the 2nd Trimester don’t also get the 3rd Trimester Flows.  Then in each Flow you can plan out all the emails you want to send in that journey - with the 1st Trimester Flow being the longest since its the one with subscribers furthest from their due date.  

Here’s additional info in Klaviyo that might be helpful:

• How date-based flows queue recipients
• How to build a birthday flow

Hope this helps get you started, if you have any further questions just ask them here!

Hi thanks for the reply.

What you’ve said makes sense - the only other questions I have thought of in relation to these types of date triggered flows are:

Every due date will be different. We ideally want a customer to fall into whichever flow at the correct point. So for example, we might send one email every week from the 1st to the 3rd trimester (total of 40 emails over 40 weeks across 3 trimesters). A customer is three weeks into their first trimester so we want them to get the 3rd email rather than having to wait to fall into the second trimester flow at 13 weeks (they’d miss a lot of content).

The only way I can think to do this is with duplicate flows. Flow 1 starts 40 weeks before due date with email 1. Flow 2 starts 39 weeks before due date with email 2. Flow 3 starts 38 weeks before due date with email 3. Etc etc. However this is very complicated!!

Another potential problem is, we can’t account for any problems the mother may encounter E.g. loss of baby,premature birth etc. We don’t want to be insensitive or cause customers distress. So all I can think of is a banner, right at the top of the email that says, if your circumstances have changed and you no longer want to see these emails - please unsubscribe here. Would you agree??

Hi @jadebiscuit, 

Yes, date-triggered flows work backwards from the date inputted, so you can create flow for each trimester worked backward from the date on each profile. This is demonstrated in the date-triggered flow documentation @retention mentioned earlier outlining how a birthday flow is set up:

Yes, I do believe there should be some way for a user to sensitively note that their circumstances has changed. While you can simply link an unsubscribe link, it should be noted that if you’re not on a paid plan, when a user unsubscribes, they will be globally unsubscribed to all your marketing and not just this specific list. If you are on a free plan, the user will not receive any promotional material from you until they resubscribe themselves.

Hi @Taylor Tarpley  - how come we wouldn’t just do 1 flow for 40 weeks - would this prove problematic? And confirming your above message meant that if they entered at 5 weeks before due date, they would only receive these 5 weeks of emails?
