Cold E-mail Campaign Setup For Jewellery Brand

I need someone who can setup a cold email marketing campaign for our jewellery brand Lovisa. We want to create a promotional Black Friday/Christmas discount campaign for our products with our existing customers who have subscribed through email. Our email list needs to be integrated and segmented in Klavio with trigger events for certain email's that are sent. We can have a quick briefing so I can show you some examples of what we need.
