Setup checklist#
- ☐ Register 2 to 5 lookalike domains and redirect them to your main site.
- ☐ Set up SPF, DKIM, and DMARC on every domain from day one.
- ☐ Create 2 to 3 mailboxes per domain and warm each for 3 to 4 weeks.
- ☐ Cap sends at 30 to 50 per mailbox per day and rotate across mailboxes.
- ☐ Monitor bounce and reply rates per mailbox; retire any that degrade.
Audit checklist#
- ☐ Confirm you are not: sending cold mail from the primary company domain.
- ☐ Confirm you are not: skipping DMARC on secondary domains because 'they do not matter'.
- ☐ Confirm you are not: buying aged domains with unknown history.
Ongoing monitoring#
- ☐ Weekly: review provider dashboards (Postmaster Tools, SNDS) and bounce logs
- ☐ Monthly: re-run the setup verification after any vendor or DNS change
- ☐ Quarterly: full audit against this checklist
Frequently asked questions#
How many emails can I send per mailbox per day?
Google Workspace allows 2,000, but for cold outreach 30 to 50 keeps you under behavioral thresholds.
Should I use Google Workspace or Microsoft 365 for cold email?
Both work. Workspace mailboxes tend to warm faster; Microsoft has stricter outbound spam filtering.
