Launching a cold email campaign with a brand-new email domain? Hold on! Sending bulk emails from a fresh domain without proper warm-up can destroy your sender reputation, trigger spam filters, and tank your deliverability.

To ensure success, you need to gradually build trust with email providers. This guide will walk you through the best practices for warming up a new email domain so your emails land in inboxes, and not spam folders.

Why Warming Up a New Email Domain is very Important

1. Avoiding Spam Filters

Email providers monitor new domains closely. A sudden spike in outgoing emails looks suspicious and can flag your domain as spammy.

2. Building a Positive Sender Reputation

Reputation matters! Gradually increasing your sending volume shows email providers that you’re a legitimate sender.

3. Improving Email Deliverability

A proper warm-up increases your chances of reaching inboxes instead of promotions or spam folders.

Step-by-Step Guide to Warming Up Your New Email Domain

Step 1: Set Up Your Email Infrastructure

Before sending a single email, ensure your domain and email settings are properly configured:

• Authenticate Your Domain with SPF, DKIM, and DMARC to prove legitimacy.
• Use a Custom Tracking Domain for email links to avoid spam flags.
• Set Up Reverse DNS & BIMI for added credibility.
• Use a reliable cold email outreach infrastructure to handle scaling properly.

Step 2: Start with Manual Emails

Before automated outreach, send one-on-one emails to trusted contacts to establish early engagement, and build your sender reputation.

Step 3: Gradually Increase Sending Volume

Follow this warm-up schedule:

• Week 1: Send 10-20 emails per day.
• Week 2: Increase to 50 emails per day.
• Week 3: Scale to 100-200 emails per day.
• Week 4+: Continue scaling while monitoring engagement.

Step 4: Maintain High Engagement Rates

• Send personalized, value-driven emails.
• Encourage recipients to reply and mark emails as important.
• Avoid spammy words and excessive links.

Step 5: Monitor Deliverability & Adjust

Use tools like PostMaster to check bounce rates, spam complaints, and engagement. If your open rates drop, slow down and troubleshoot issues.

Properly warming up your email domain ensures better inbox placement, stronger engagement, and more replies.
