I’m planning to switch my branded sending domain, but I don’t want my deliverability to drop.
How can I run two domains in parallel in Klaviyo so I can warm up the new one while keeping the old one active?
Specifically:
-
Can I add a new sending domain without removing the old one?
-
Is it possible to choose which domain to send from on a per-campaign or per-flow basis?
-
What’s the best way to split sending (marketing vs. transactional) during the warm-up phase?
-
Do I need to set up separate sending profiles for each domain?
-
How do I gradually increase volume from the new domain inside Klaviyo?
