Importing and Tagging customers from mailchimp

Shopify Discussion
1

I currently have 5000+ contacts in mailchimp that I’m looking to import as customers in Shopify, so I can manage all my mailing etc through Shopify.

We have multiple ‘audiences’ in mailchimp which we use to group our contacts. Some contacts might be in multiple audiences in mailchimp. I want to export these audience groups and import them in Shopify and (since I can’t actually group contacts) I would need to use tags to segment these groups for mailing lists etc.

The problem I’m having is that if I import ‘Group A’ for example , and tag all the contacts in this group as ‘Group A’ ( so that they are tagged for Group A in shopify) , When I go to import Group C and there’s some customers in this group that are already tagged with ‘Group A’ , When I import the customers to add the tag ‘Group C’ to this list, those contacts that were previously tagged as Group A will lose the Group A tag and only have a Group C tag - Is there any way to avoid this ?

(To clarify, I want to import 1 list of contacts, add a specific series of tags to these contacts, and then import a second list of contacts that will have a different set of tags, but will add these tags to customers that are already in my shopify database, rather than overriding the previous tags with the new tags from the most recent upload(s)).

I hope this makes sense - Please let me know if more clarification or information is needed!

Thanks!

Pre-import, if using CSV do the pre work in excel for al customers.

Just add the Group-A-tag to the import CSV.

If your using an app/integration you need to take it up with that app erroneously deleting tags on existing customers; it’s probably assuming it’s a source of truth and wiping out any tag it doesn’t have which is silly.

Post-import, Alternatively try creating a shopify-flow automation to move customer tags to a customer metafield

https://help.shopify.com/en/manual/shopify-flow/reference/actions/update-customer-metafield

Then a flow to readd all those metafield entries back as customer tags.

Alternatively use an app like mechanic to script the automation,

If you need automation services then contact me by email or see contact info in forum signature.
ALWAYS please provide context, examples: store url, theme name, post url(s) , or any further detail in ALL correspondence.

The problem is I can’t identify every individual who is needing the multiple tags (group A and group c) and it won’t be an entire group that will need multiple tags, only certain individuals in each group. So I don’t know how I would work through this pre or post import.
