When the first business mail from a freshly registered domain lands in spam, the reflex is “the domain is too young.” Age alone is not the verdict. Receivers may weight domain age, but the score that sticks is reputation: authentication, complaint rates, volume ramp, and prior abuse — for the domain and the sending IP.
On EuroVDC corporate email, MX points to securemail.eurovdc.eu (priority 10) and a typical SPF is v=spf1 mx ip4:45.84.90.12 -all. With nameservers ns1.eurovdc.eu / ns2.eurovdc.eu you publish records from the panel. That is the floor; reputation accumulates from how you send. DNS layout: change nameservers and manage DNS records.
What age explains — and what it does not
Brand-new domains often face stricter thresholds. A three-year-old domain with broken SPF/DKIM and bursty cold volume still lands in spam. A weeks-old domain with aligned MX/SPF/DKIM/DMARC, low complaints, and a stable From can reach the inbox. Age is a signal, not a substitute for reputation.
Where reputation accumulates
- Egress IP and reverse-DNS integrity (shared egress shares neighbour risk).
- Complaint and bounce rates for the domain + IP pair.
- SPF/DKIM alignment and DMARC policy — details: SPF, DKIM, DMARC and deliverability.
- Early volume: blasting cold lists burns trust fast.
A practical first-30-days ramp
- Create mailboxes and aliases: create and manage email accounts.
- Verify MX, SPF with
-all, DKIM, and at least DMARCp=none. - Exchange low-volume business mail with known parties; defer bulk marketing.
- Watch spam folders and bounces daily; keep link and attachment patterns stable.
- If complaints appear, fix list source and unsubscribe, then cut volume.
Common mistakes
Moving an entire newsletter to a new domain in one day; treating a parked or previously abused name as “fresh”; sending via random PHP mail() from a web host IP. The corporate path: Sofia EU-hosted corporate email with correct DNS.
FAQ
How many days until a domain is “safe”?
There is no universal day count. Filters mix age, reputation, and auth. A clean ramp matters more.
Is SPF alone enough?
No. Without DKIM alignment and a stable From, young domains stay fragile. DMARC reports inventory your sources.
Will a shared egress IP kill my reputation?
Neighbour abuse can spill over; corporate products control egress and policy. On your own host, keep rDNS and volume disciplined.
Do I need warm-up tools?
For small B2B correspondence, usually not. Cold bulk needs a controlled volume climb — not a magic plugin.
Can I transfer old-domain reputation to a new one?
No automatic transfer. The new name builds its own signals; use parallel low-volume cutover.
