Multiple Domain System

Multiple domain systems extend email reach beyond your primary domain. Each has its own sender reputation and acts as an individual shield to protect your core domain from email fatigue and potential blacklisting.

These alternate domains feel familiar to your primary brand, but operate independently.

Consider an example to illustrate:

You own outboundrocks.com, but you also send email from tryoutboundrocks.com, seeoutboundrocks.com, and outboundrocksplus.com.

By spreading your send volume across multiple domains, you avoid overloading your main domain and potentially triggering spam filters.

Think of it like wearing a bulletproof vest for each domain. Even if one takes a hit, the others stay protected, and your main brand remains untouched.

This helps you maintain an overall clean sender reputation, which is critical for email deliverability and engagement.

Deliverability and Sender Reputation

Since your primary domain is used for internal communications and official business interactions, it is important to protect its reputation.

Larger SDRs often forget this, resulting in high churn rates and ineffective outreach efforts for their customers.

Why is it important to maintain the health of your sender reputation? We’ll summarize them below:

Spam filters target domains with high volume or suspicious activity. By implementing multiple domains, you spread your reach, diluting potential red flags for any one domain. Each domain maintains its own clean slate, protecting your primary brand from reputational damage.

✅ With multiple sending domains, you’re less likely to trigger spam filters trained on specific IP addresses or domain patterns. Each domain represents a fresh identity, minimizing the chance of triggering automated suspicion.

If one domain gets flagged, it doesn’t sink your entire ship. With multiple domains, you can isolate and remediate the problem in that specific domain while your other domains continue to run smoothly. This minimizes the impact and allows for faster reputation recovery.

By distributing your sending volume across multiple domains, you stay within individual email service providers’ (ESPs) daily limits. This avoids throttling and ensures a higher percentage of your emails reach inboxes, not spam folders.

How to send emails with different email domains

Protecting your sender reputation with a multi-domain system requires careful setup and management of alternate domains.

Follow these step-by-step instructions to do it:

  • Select alternate domains: select domain names that are similar to your primary domain. For example, if your primary domain is outboundrocks.com, consider domains such as tryoutboundrocks.com, seeoutboundrocks.com, and outboundrocksplus.com.
  • Set up email accounts: create email accounts on each alternate domain with variations such as sales_guy_n1@tryoutboundrocks.com, sales_guy_n2@seeoutboundrocks.com, and so on.
  • Purchase domains: purchase the selected domain names from a reputable domain registrar.
  • Access advanced DNS settings: log in to your domain registrar’s control panel and navigate to the Advanced DNS Settings section.
  • Implement 301 redirects: set up 301 redirects for each alternate domain to redirect traffic to your primary domain. For example, redirect tryoutboundrocks.com to outboundrocks.com. Ensure that the redirects are working correctly by visiting each alternate domain and confirming that it redirects to your primary domain.
  • Configure an email sending system: set up an email sending system that allows you to send a significant volume of email per day. Make sure it meets the safe send limits to avoid triggering spam filters.
  • Safe send limits: familiarize yourself with the safe send limits for your email sending system. Adhere to these limits to maintain a positive sender reputation.
    Email account management:
  • Efficiently manage your email accounts within the send system. Rotate accounts, change sending patterns, and avoid any suspicious activity that may trigger spam filters.

Important: start with a manageable number of domains, around 8 to 10, to get your lead generation efforts off the ground. Then, monitor performance and adjust the number of domains as needed.
