Like the title said, I have a client who is migrating from MailChimp. They also want to set up dedicated sending domain. The Klaviyo account is new. They have past open and click data from Maiclhimp. I already integrated Mailchimp and Klaviyo.
My main issue is warming up. Do I need to warm up twice?
Should I warm up for 2-4 weeks then set up dedicated sending domain or set up dedicated sending domain too and warm up?
How should I proceed about the warming up process?
