How to grow a B2B newsletter list via cold outreach (ethically)
Cold subscriber acquisition is sensitive — anti-spam laws + reader expectations mean "buy a list and blast" is dead. Done right, cold-invite outreach is the fastest way to grow a focused B2B newsletter.
Step 1: define WHO your newsletter is for
Specific: "VP Engineering at SaaS companies $5-50M ARR". Generic: "B2B leaders". Specific wins.
Step 2: build the prospect list
LinkedIn Profiles via Kavex with title + company filters. 200-500 names is enough to start.
Step 3: invite, don't enrol
Personalised opt-in email. "I write a weekly newsletter on <topic>. Here's the latest issue. Want it weekly? Reply YES or just click unsubscribe."
Compliance
GDPR + CAN-SPAM both allow cold outreach to business addresses for legitimate-interest purposes when there's a clear opt-out. Honour every unsubscribe within 24h.
