The recent evolution in cold email strategy, particularly the shift to using multiple domains to send a limited number of emails per day, is a response to several key challenges and developments in email marketing.

Background

With increasing security and restrictions  by major email service providers like Google and Yahoo on spam and bulk emailing, sales teams have had to rethink their strategies. The old method of sending a large volume of emails from a single domain often leads to  a blacklisted domain, thus harming the overall effectiveness of an email campaign​ 

That’s why in today’s cold email game, bulk senders are now required to

Set up DKIM, SPF, and DMARC records to authenticate and validate their domains.  email by setting up SPF, DKIM, and DMARC records

Make sure the Unsubscribe button is present in all emails, and then honor the un-sub request within 1 to 2 days.

Make sure that the spam rate is lower than 0.3%.

Violation of these requirements affect the entire domain and not just the individual accounts. Having multiple domains will help you manage deliverability and reputation while complying with your email service providers.

Here are 6 important reasons why setting up 10 domains for your cold email strategy is crucial:

Risk Mitigation:

Using multiple domains to send out cold emails helps distribute the risk of blacklisting or penalties from email service providers (ESPs). If one domain gets flagged or blacklisted for any reason, it does not impact the deliverability of emails from the other domains, thereby protecting the overall email outreach efforts and sustaining campaign continuity​.Enhanced Deliverability:

Each domain can be optimized and warmed up individually, ensuring better control over deliverability metrics. This includes setting up domain authentication protocols like SPF, DKIM, and DMARC correctly, which are critical for ensuring emails reach the inbox rather than the spam folder. Multiple domains allow for a segmented approach to managing these setups, which can be tailored according to the specific uses and target audiences of each domain​.Avoidance of Sending Limits:

Major ESPs like Google, Outlook, and others impose sending limits on how many emails can be sent from one domain per day. By spreading the email load across several domains, you effectively multiply the allowable sending limit, which enables scaling up operations without hitting these caps, thus maintaining a steady flow of outreach without service interruptions.Reputation Management:

Each domain accrues its own reputation with ESPs based on the quality of the emails and the recipient's reactions (like open rates, direct replies, marking as spam, etc.). By managing multiple domains, businesses can experiment with different strategies and content styles to see which performs best, without risking the reputation of their primary or other business-critical domains​.Testing and Segmentation:

Different domains can be used to test various market segments or campaign strategies without affecting each other. This is particularly useful in A/B testing where slight variations in email content, design, or sending times can be evaluated independently across different domains to deduce what works best for each target audience.Professionalism and Specialization:

Having separate domains for different purposes or products can also project a more organized and specialized image to recipients. This can increase the perceived credibility and relevance of the emails, which in turn can enhance engagement rates.

Implementation Steps

To implement this strategy effectively, the following steps are crucial:

Domain Setup:

Purchase and set up multiple domains, preferably related to your main domain to maintain consistency but distinct enough to separate the outreach efforts from your primary business communications.Email Configuration:

Set up email authentication standards such as SPF and DKIM for each domain to ensure that emails are correctly authenticated, minimizing the chances of landing in spam folders​.Lead Generation:

Focus on acquiring high-quality leads. Use tools like LinkedIn Sales Navigator to build a list of prospects that are most likely to engage with your emails, enhancing the effectiveness of each sent email.Email Infrastructure:

Use email service providers that support bulk email operations and provide tools for managing multiple domains and monitoring deliverability and reputation.Ramping Up:

Start with a lower volume of emails per domain and gradually increase, while constantly monitoring the response rates and adjusting strategies as necessary.

Tools and Software

To support this infrastructure, several tools and software are recommended:

EmailChaser: Ideal for managing the sending process and ensuring that emails do not land in spam​.QuickMail: Offers features like inbox rotation and integration with warm-up services to maintain the health of your email domains.Dripify: Useful for setting up and managing separate email domains specifically for cold outreach.

Conclusion

The strategy of using multiple domains to send a controlled number of emails per day represents a sophisticated approach to modern cold emailing. By focusing on deliverability, personalization, and compliance with email sending regulations, businesses can enhance their outreach effectiveness without compromising their domain health and reputation. This method not only adheres to the stricter regulations imposed by email service providers but also aligns with a more respectful and targeted approach to prospective clients.
