<b>Secondary sending domains: tooling can't fix bad architecture</b>
No warm-up tool saves you if your domain strategy is wrong. This is upstream of software.
The pattern that works
— Buy 3-5 lookalike domains (.com, get-, try-, .co variants of your brand)
— 2-3 mailboxes per domain, max — more invites scrutiny
— Redirect all to your main site so they're not orphaned
Tools that manage this
— Mailforge / Maildoso: provision domains + mailboxes pre-configured with SPF/DKIM/DMARC, hours not days
— Google Workspace direct: cheaper per seat but manual DNS, no bulk provisioning
Mailforge
— Pros: bulk domain+mailbox setup, auth pre-done, built for cold
— Cons: shared infrastructure reputation risk, less control
The tradeoff: managed providers save setup pain but you inherit neighbor reputation. Self-hosted Workspace is more work, cleaner reputation.
Verdict: 4/5 Mailforge for speed, 4/5 Workspace for control freaks.
Who it's for: anyone scaling past one domain — never send cold from your primary.
