If you are new to Klaviyo, and have historical email engagement data from your previous ESP (Email Service Provider), which warming process should you use to warm your domain?

Standard warming is the correct process when you have historical email engagement data from a previous ESP. This allows Klaviyo to leverage your existing recipient engagement to gradually increase sending volume and establish a positive sender reputation with internet service providers (ISPs). IP warming is typically for senders with a new, unestablished IP address and no prior sending history. The platform introduction process is a broader onboarding sequence for new Klaviyo users, not a specific warming strategy.
