Frequently Asked Questions
Outbound Infrastructure & Economics FAQs
Why are secondary domains required for cold outbound?
Sending cold email from your primary business domain risks domain-level spam blacklisting, which will degrade daily internal and client correspondence. Secondary domains isolate outbound deliverability, preserve root domain reputation, and allow dedicated SPF, DKIM, and DMARC alignment.
How many cold emails can one mailbox safely send per day?
To maintain 98%+ inbox placement across Google Workspace and Microsoft 365, each mailbox must be capped at 30 to 35 cold emails per day, following a strict 2 to 3 week automated warmup ramp. Higher sending volumes trigger spam filters and ruin mailbox sender reputation.
How does the B2B Outbound Pilot compare to hiring an in-house SDR?
An in-house SDR requires 2-3 months to recruit and ramp, costly tooling subscriptions ($500-$1,000/mo), and a fixed monthly salary with high turnover risk. The D2 Outbound Pilot delivers a fully operational pipeline in 14 days with verified ICP data, secondary domain setup, and guaranteed discovery meetings at a fraction of the cost.
What reply and meeting conversion rates are realistic?
With generic spray-and-pray lists, reply rates rarely exceed 1%. With signal-based outbound (targeting companies hiring for relevant roles, adopting specific tech stacks, or undergoing leadership changes), reply rates reach 3% to 6%, with 35% to 50% converting into qualified discovery calls.
