Mistake: buying the cheapest bulk mailboxes on shared IPs

Mistake: buying the cheapest bulk mailboxes on shared IPs
The $1.50/mailbox Google Workspace resellers often share IP ranges and reuse burned domains. You inherit a neighbor's reputation on day one and warm-up never catches up.

The fix: pay for dedicated infrastructure or use a provider with per-tenant IP isolation — Google Workspace direct, or a managed inbox provider that discloses IP allocation. For volume, Amazon SES on a dedicated IP gives you a clean lane you control.

Pros / Cons of dedicated vs cheap bulk:
— Pro: reputation is yours alone, good or bad
— Pro: warm-up actually compounds
— Con: 3-5x the per-mailbox cost
— Con: SES means managing your own deliverability, no hand-holding

Verdict: 4/5 for dedicated, 1.5/5 for mystery bulk. You're renting someone else's spam history.

Who it's for: anyone who picked mailboxes by price-per-seat alone.
