Setting Up Your Email Infrastructure: Dedicated vs Shared IPs for Cold Email Sending

New Domain Setup: Dedicated vs Shared IPs and Subdomains for Sending

So, you've got a shiny new domain, and you're ready to send some cold emails. Great! But before you hit that "Send" button, there are some critical infrastructure decisions you need to make.

Dedicated vs Shared IPs: What's the Difference?

An IP (Internet Protocol) address is like a home for your emails. A dedicated IP means you've got the whole house to yourself, while a shared IP means you're sharing that space with others.

Dedicated IPs offer greater control over your email reputation, as you're not affected by other users' behavior. They're ideal if you're sending high volumes of emails or require strict deliverability standards. However, they can be more costly to maintain and require diligent management to ensure a healthy email reputation.

Shared IPs are more budget-friendly but come with the risk of being affected by other users' actions. If your shared IP neighbors send spam or engage in other poor email practices, their actions could impact your deliverability. However, good Email Service Providers (ESPs) monitor shared IPs closely to ensure all users adhere to best practices.

When to Choose Dedicated IPs

• You're sending over 50,000 emails per month.
• Your brand value is high, and you require consistent high deliverability.
• You're willing to invest time and resources into maintaining your IP reputation.

When to Choose Shared IPs

• You're on a budget and can't afford a dedicated IP.
• You're sending under 50,000 emails per month.
• You're willing to trust your ESP's reputation management practices.

Warming Up Your IP

Whether you choose a dedicated or shared IP, you need to warm it up before sending large volumes of emails. Warming up an IP involves gradually increasing your sending volume to build a positive email reputation with ESPs and Internet Service Providers (ISPs).

To warm up an IP, start by sending a few hundred emails per day and monitor your deliverability. Gradually increase your volume while maintaining high open and low spam rates. Most ESPs flag accounts sending over 50 cold emails/day from a new domain, so warm up your IP responsibly to avoid deliverability issues.

Subdomains for Sending: Protect Your Primary Domain

To safeguard your primary domain's reputation and improve deliverability, create subdomains for sending cold emails. For example, use email.yourdomain.com instead of yourdomain.com for your cold email campaigns.

Configure your subdomains with MX records that point to your ESP, and ensure your SPF, DKIM, and DMARC records are properly set up. Doing so will authenticate your emails, improve deliverability, and prevent spoofing.

Summary

When setting up your email infrastructure for a new domain, consider the following:

• Decide between dedicated and shared IPs based on your sending volume, budget, and email reputation management preferences.
• Warm up your IP to build a positive email reputation and improve deliverability.
• Create subdomains for sending cold emails and configure them with MX records, SPF, DKIM, and DMARC records to authenticate your emails and protect your primary domain's reputation.

By following these best practices, you'll be well on your way to successful cold email campaigns that reach your prospects' inboxes and drive conversions.
