A common expectation that leads to disappointment.
WHAT PEOPLE EXPECT
That moving to a dedicated address resolves mail landing in spam.
WHAT ACTUALLY DETERMINES DELIVERABILITY
Authentication: SPF, DKIM, DMARC, and reverse DNS
The From address being on your own domain Content and formatting
Recipient engagement: opens, replies, and the absence of complaints
Bounce rates Consistency of volume The sending IP's history
The address is one factor among many, and usually not the limiting one.
WHY A NEW DEDICATED IP CAN BE WORSE
It has no history. Receiving providers treat unknown addresses cautiously, and without a warming period mail may be filtered more heavily than it was on a shared address with an established record.
THE RIGHT ORDER OF WORK
- Fix authentication.
- Send from your own domain using authenticated SMTP.
- Clean your recipient list.
- Move bulk sending to a dedicated provider.
- Only then consider whether a dedicated IP adds anything.
Most deliverability problems are resolved at step one.
