PRE-WARMED
Pre-warmed cold email domains, sending on day one
Pre-warmed cold email domains are aged domains from Slicey’s own pool that have been warming and sending for five months or more. They come with 100 Microsoft inboxes, are assigned the moment you pay, and send at full volume on day one instead of day 15.
What a pre-warmed domain includes
An aged domain, five months or older, with a clean sending history on Slicey infrastructure.
100 Microsoft 365 inboxes, already warm.
SPF, DKIM, DMARC and the stealth redirect already in place.
200 to 500 sends per domain per day from day one, depending on the tier.
Daily deliverability tracking, burn alerts and swaps on request.
No setup fee and no registration fee.
Pre-warmed domains vs email warmup
Email warmup tools send automated messages between inboxes to build a reputation over weeks. A pre-warmed domain has already done that work with real sending, so you skip the ramp entirely. The trade-off is price and stock: pre-warmed domains cost $97 instead of $49 and the pool is limited.

What waiting two weeks costs
A single domain on the Balanced tier sends 300 emails a day. Two weeks of warmup is about 4,200 emails per domain that never go out. If you are launching a campaign this week, that is the number to weigh against the $48 monthly difference.
Who pre-warmed domains are for
Agencies onboarding a client who wants results this month.
Teams replacing burned domains without a gap in sending.
Founders testing an offer who cannot wait two weeks for signal.
If you have time to ramp, new Microsoft domains at $49 are the better deal.
