multiple subscription group update
Adding subscription group to your email program is a great way to retain customers from on overall exit. Unfortunately adding the program starts all existing customer as unsubscribe. Luckily there is a webhook to switch them on, unfortunately I am only able to switch on ONE at a time. Has anyone attempted to switch multiple subscription group at a time?
Hey Ravn - I imagine you mean to bulk update everyone to be "Subscribed" to a specific subscription group? Yea afraid you can't use the Canvas "Update User" step for this or do a batch update via the API, so the best way would be either :
1. Upload a CSV with 3 columns: external_id, subscription_group_id, subscription_status. *See this documentation*
2. Run a webhook to update users with the subscription group. Ensure you rate limit the # of users getting this per minute according to the rate limit of the API. If I recall its 50k per minute.
Hope that helps,
Hi Ben,
Yes I would like to do a bulk update to everyone. I am using a webhook which successfully updates all subscribed/opt-in customers to "turn-on" for a specific subscription group in a sandbox test environment. The test environment had 1.2M contact which took nearly 4 hours to turn on 1 subscription group while our true list consist of 42M plus customers with 6 subscription group.
The rate limit for this is 5k per minute which will lead us over 40 days (at least) so this brings up a few hiccups. Updating 1 subscription group per run will take us at least 240 days to back-fill 6 subscription group for 42M plus and that runs into potential issue with new customer switch since they will run simultaneously and be part of the 5k threshold.
For that reason, I am hoping to switch all 6 subscription group to all subscribed/opt-in customers in one run then let the new subscriber webhook kick in after the run rather than reduce backfill and new customer switch. I tried testing multiple subscriber group switch which didn't work sadly. Hoping someone had better luck.
