1. Domain Health
Why this matters: Your domain's reputation is the foundation of email deliverability. If your domain appears on blacklists or lacks proper DNS authentication, even the best copy won't reach inboxes. Traditional providers require weeks of manual setup and monitoring—ColdSend handles this automatically.

2. Sending Warmth
Why this matters: Email providers track sender reputation through complex algorithms. New domains need 2-6 weeks of careful "warming" to build trust with Gmail and Outlook. Skip this, and your emails go straight to spam—regardless of content quality.

3. Copy & Creative
Why this matters: Even with perfect infrastructure, spam-trigger words and weak subject lines kill deliverability. Modern filters analyze content patterns, sentiment, and engagement signals. One "URGENT!!!" or "FREE MONEY" can undo weeks of reputation building.

4. List Integrity
Why this matters: Invalid emails cause hard bounces, which immediately damage sender reputation. A 5%+ bounce rate can trigger spam folder placement for all future emails. Always validate lists before sending—especially when using scraped or purchased data.
