Hi - We are new to Klaviyo and are just setting it up, have integrated with our Magento store as well as Mailchimp. There are now 2 lists created in Klaviyo - one from Mailchimp and the other named as the default Newsletter which is syncing from Magento.
However, Mailchimp has not been synced with our store for about a year so there may be issues with unsubscribed contacts not synced between the 3 platforms. We have been using Mailchimp to send newsletters without the store sync.
This would make the Mailchimp list up to date with the contacts who have unsubscribed, but not our Magento store.
We have some questions:
How can we make sure we will not be contacting anyone who has opted out from any list?
Should we merger the 2 lists to create a Master list?
The default Newsletter list is much larger than the Mailchimp list - is there a reason for this?
Should we delete all lists or the account and start again so we have a clean contact list
Thank you in advance.
