Yes, change quite a bit. As planned, Monday would likely burn both domains within a few days.
## The three big problems
**1. Volume vs. mailboxes**
600 a day across 2 inboxes is 300 per mailbox. The safe range is 20-30 per mailbox per day, and new mailboxes should start much lower. At 600 a day you need roughly 20-25 mailboxes across 8-10 domains, plus 10-20% spare warmed domains. Follow-ups count toward daily volume too.
**2. No warmup**
Domains bought yesterday aren't ready by Monday. New mailboxes need 3-4 weeks:
- Weeks 1-2: warmup only, plus a few real emails to people likely to reply.
- Weeks 3-4: start cold sends at 5-10 a day per mailbox and ramp gradually.
Buying more domains and mailboxes today starts the clock. Realistically, 600 a day is about 4-6 weeks away. The 2 existing inboxes will top out around 40-60 a day once warmed.
**3. An 18-month-old list**
People change jobs and companies reorganize, so a list that old will likely bounce well past the 2% ceiling. A single day with several percent bounces can trigger a review at Google. Do this before upload:
- Ask the vendor for a refreshed pull if possible.
- Run the whole list through a verifier (Truelist, Bouncer, MillionVerifier, NeverBounce, etc.), and re-verify anything older than about a week at send time.
- Set a policy for catch-all domains, such as excluding them or sending them last in small batches.
- Expect to lose a large share of the list. Stale titles also mean the targeting may be wrong even where the address works, so spot-check a sample against LinkedIn.

## Setup checklist before first send
- SPF, DKIM, and DMARC (start at `p=none`) on each domain, aligned to the From domain.
- Mailboxes from properly licensed Google Workspace or Microsoft 365 tenants, not cheap reseller inboxes. One inbox per real-looking person, never aliases.
- If you can, match mailbox provider to your prospects' mail hosts (check MX records).
- Plain text only, no link in email 1, open and click tracking off.
- Email 1 under about 80 words, with copy varied by segment rather than one identical body.
- An opt-out line and your postal address in every email.
- Redirect the new domains to your main site.
## Stop-loss rules to set up before launch
- Bounce rate above 2%: pause the campaign and re-verify.
- Inbox placement below ~70%: pull the mailbox and return it to warmup.
- Spam complaints approaching 0.1%: pause and cut volume.
- Reply rate under ~1% after 300+ sends: stop and fix the targeting or offer. More volume makes it worse.
## Suggested timeline
- **Now:** buy the remaining domains, provision mailboxes, set up authentication, start warmup.
- **Weeks 1-2:** warmup only. Refresh and verify the list, and write and segment the copy.
- **Week 3:** begin cold sends at 5-10 a day per mailbox, with seed placement tests first.
- **Weeks 4-6:** ramp toward 20-30 per mailbox as bounces and placement hold.
If you need to send something Monday, run a small batch (around 20-40 a day total) from the 2 new inboxes, to a freshly verified, hand-picked slice of the list. It will still be far from 600 a day.
