Your domain reputation is an asset
Email providers score every sending domain over time. If cold campaigns damage that score, your normal client and team email can start landing in spam.
What isolated domains do
Outbound campaigns send from separate domains set up just for prospecting. If one of them runs into trouble, your main domain is unaffected.
Why warm-up matters
A brand-new sending domain has no history. Warming it up gradually builds a track record before real campaigns start, which improves the chance your emails are seen.
This setup takes time and tooling, which is why it's a good fit to hand to a specialist.
