Ending due to non-compliance

Hey {first_name} - It's {rep_name} from {brand_name}. {{personalization based on content}} We really appreciate the work we've done together. But, there have been a few issues that put us off track from our agreement. {brand_name} has a certain standard we aim to keep in all our partnerships. So, we need to wrap up our current collab. Hope this makes sense. Can I send you some more info? {rep_name}
