Impacted by spam bot attacks

Hi Everyone,

I wanted to have a conversation about spam attacks on one of our stores which has been happening more frequently in the last 2 months. We’ve had our deliverability rates impacted and even our active profile count has increased which has impacted billing.

Support did help us with removing the profiles but this happens after the issue has happened and the damage has been done.

Has anyone else faced this and can give us a hand?

Thank you,

Welcome to the community!

If you are seeing these profiles sharing the same domain on the email address, you could use mail ward from the app marketplace to block that domain entering your Klaviyo flows and it is free, so that might be worth a try otherwise if you enable double opt in that should hopefully stop them from entering your lists

Hope that gets resolved for you!

We are seeing a similar issue, was this the fix?

Somewhat, there is a limit on the domain blocking for free. I do appreciate the help!

Glad that worked for you, you can pair it with flow filter conditions but it wouldn’t auto suppress. You could use Klaviyo’s API in a custom solution for that instead though!
