The time required to complete email warm-up depends mainly on whether your domain is new or already in use.
If your domain is new, it’s important to warm up your email accounts consistently for at least 3 to 4 weeks before starting any outreach. This helps build trust with email providers and gives your domain a stable sending reputation.
If your domain is not new and doesn’t have any major reputation issues, warming up for 2 to 3 weeks is usually enough.
Once you’re ready to start outreach, do not stop warm-up.
Instead, lower your daily email sending limit for campaigns and keep warm-up running in the background. This helps balance your sending activity and protects your reputation.
If your outreach campaign does not perform well for any reason, continuing warm-up ensures your domain reputation does not take a hit.
Email warm-up is not a one-time setup. Keeping warm-up active even while running campaigns helps maintain healthy deliverability and long-term inbox placement.
