Email Warmup Guide

Provides structured plans for warming up new email sending domains and IP addresses to establish strong sender reputation.

Usage

Ask for warmup schedules, monitoring advice, or troubleshooting during the warmup process.

Examples

• "Create a 30-day warmup plan for my new sending domain"
• "What metrics should I monitor during IP warmup?"
• "My warmup is stalling at Gmail — what should I do?"

Guidelines

• Start with your most engaged subscribers during warmup
• Increase daily volume by 30-50% each day, not all at once
• Monitor bounce rates, spam complaints, and inbox placement daily
• Pause and investigate if bounce rates exceed 5%
• Authenticate with SPF, DKIM, and DMARC before starting warmup
