What’s the right approach when IP range reputation tanks?

IP range reputation issues:

Assess the damage:

How bad is the reputation?

Blocklisted or just poor?

Shared IP or dedicated?

Options:

Wait and improve: Fix practices, wait for reputation to recover

New IP: Requires full warmup, but fresh start

Shared pool: May be affected by other senders

Different allocation: Request different IPs from provider

Considerations:

Domain reputation may follow regardless of IP

New IP does not fix underlying problems

Warmup takes time

Fix root causes first, then consider IP change if needed.

New ship helps only if the cargo and crew practices also change.
