Hi @Marania!

Essentially, this is going to boil down to the details of how you “took control” of the new store. Did the previous owners of the store also transfer an old Klaviyo account?

From a deliverability standpoint, it’s possible you’re seeing drops in open rates because some inboxes can identify when you are using the same branding/logos/lists as a different sender, and mark them as suspicious. In other words, it could be a consequence of the old sending infrastructure not being brought over. 

That said, I would recommend the following Community threads to help improve your overall deliverability:

Hi @Marania 

When you say that you took control of an online recently from previous owner, did you mean - 1) moving the store on to a new top level website domain or it’s the same TLD? 2) Using the same sending domains on new Klaviyo account or created a new sending domain setup.

In either scenario, when you go through any migration phase (from deliverability perspective), it’s necessary to establish the sending reputation with mailbox providers by following email best practices. I’m not sure whether the migration is done completely and you have set the expectations with the list once you have taken control.

- Have you gone through any warmup & rampup exercise while ensuring you have suppressed the blacklisted data on Klaviyo account?

- Was there any spike in negative KPIs like spam complaints, bounces, or unsubscribe?

- What is your domain/IP reputation health?

- Have you tried checking where your emails are landing - in inbox or spam?

Last but not least, fluctuations in open can happen anytime and should not be a concern unless there’s an impact of other important KPIs too.

Let me know if you have any further questions.

Mohsin
