Frequently Asked Questions
Microsoft 365 or Google Workspace for cold email?
Microsoft 365 delivers better to Outlook recipients and tolerates 20-30 emails/inbox/day. Google Workspace delivers better to Gmail recipients and limits to 15-20/inbox/day. Best practice: 60/40 mixed split for diversification across both major recipient platforms.
Premium inboxes vs cheap inboxes — which has better ROI?
Premium inboxes win on TCO at any scale beyond 10 inboxes. Premium 90-95% inbox placement and 5-7% suspension beats cheap 50-70% placement and 25-40% suspension. True cost per delivered email is 3x lower on premium.
Pre-warmed vs self-warmed cold email inboxes?
Pre-warmed inboxes deliver $5-10/month/inbox premium but save 4-12 weeks of warmup wait time. ROI math favors pre-warmed for any operation that needs pipeline within 1-3 months. Self-warmed only wins for solo operators with extreme budget constraint.
