🤔 Why and How to set up Multiple Email Accounts
You're ready to start reaching potential clients through email—great! Cold email outreach remains one of the most powerful strategies for businesses to connect with new prospects. However, it's crucial to protect your primary domain and ensure your emails land in recipients' inboxes.
The best approach is to use a separate domain dedicated to cold outreach. In this guide, we'll walk you through the essential steps to setting up an additional domain and share best practices to maximize email deliverability.
Additionally, we recommend sending no more than 40 emails per account per day—ideally even 30. If you aim to reach a larger audience, setting up multiple email domains is essential.
💡 What is a domain?
If your email account is noah@seleqt.ai the part “@seleqt.ai” is referred to as your domain. So you probably have multiple email accounts for your business under the same domain.
⁉️ Why Use a Separate Domain?
You might be wondering, "Why can’t I just use my main domain?" The answer is simple: to protect your primary domain’s reputation.
Cold emails often have lower engagement rates and may receive spam complaints. By using a separate domain, you ensure that any negative feedback does not impact your main domain’s sender reputation. This means that if some of your sales emails end up in spam, your primary domain remains unaffected, preserving its credibility.
An additional benefit is that a dedicated domain allows you to track and analyze your outreach efforts separately, without mixing data from your main business communications.
🛠 Setting Up a Separate Domain
Now that you understand the importance of using a dedicated domain for cold outreach, let’s walk through the setup process.
1. Choosing the Right Domain Name
When receiving an email, the first thing people check is the sender's address. Your domain should be trustfull and align with your brand identity.
You also want to keep costs low while maintaining a professional appearance. Here’s how:
Opt for a more affordable domain extension. If your main domain is expensive (e.g., .com or .ai), consider purchasing a more budget-friendly alternative like .co.
Example: If your main domain is @seleqt.ai, you could use @seleqt.co as a cold outreach domain.
Modify your domain slightly while keeping brand consistency.
Example: If your main domain is @seleqt.ai, you could go with @seleqtai.co instead.
For larger outreach campaigns, you can even combine both approaches and buy multiple domains.
Additionally, it’s crucial to set up domain redirection. If someone searches for your outreach domain on Google, they should be directed to your main website. For example, searching www.seleqtai.co should redirect visitors to www.seleqt.ai. You can configure this easily through your domain provider in just a few minutes.
2. Buying the Domain & Setting Up Email Accounts
Once you’ve selected a domain, the next step is to purchase it and set up your email accounts.
A few key recommendations:
✅ Buy 1 domain per 2-3 email accounts – you don’t need a new domain for each email.
✅ Keep your outreach volume low to maintain deliverability (max 40 emails per account per day).
To register your domain, we recommend GoDaddy, as it is fairly easy to use. Simply type in your desired domain, search, and purchase within minutes.

Once you've found your preferred domain, add it to your cart. Be sure to check the number of years you're purchasing, GoDaddy may default to a 3-year plan as an upsell. We recommend selecting a 1-year registration to keep costs low and maintain flexibility.

When you proceed to checkout, you'll have the option to purchase a custom email address. We recommend selecting the most affordable option: “Microsoft 365 Email Essentials” at just €1.89/month. This is significantly cheaper compared to purchasing directly from Microsoft, where the same service costs €5.60/month.

At checkout, you can select the number of email accounts you want to purchase.
For example, if you plan to create two email accounts under the same subdomain, you could set up:
📧 noah@seleqt.co
📧 noahvrijn@seleqt.co
This allows you to efficiently manage multiple outreach addresses under a single domain.

Great, you now have multiple email accounts under a separate domain and can almost get started with your outreach efforts 😁!
🚀 Maximizing Email Deliverability for New Accounts
After setting up your new email accounts, you can’t immediately start your outreach. To ensure your emails land in the primary inbox instead of spam, you need to complete two crucial steps.
1. The Warm-Up Process
Jumping straight into sending 30-40 emails per day without any prior activity will trigger spam filters, reducing your email deliverability.
To prevent this, you must first warm up your email accounts. This involves gradually sending and receiving a small number of emails per day, increasing the volume over time. This process helps build trust with Internet Service Providers (ISPs) and signals that your domain is legitimate.
⏳ Warm-up duration: ~2 weeks
💡 We can handle the warm-up for you! Simply create a dummy password for your email accounts, and we’ll take care of the rest. However, before doing this, you need to configure the correct email protocols.
2. Setting Up Email Protocols (IMAP, SMTP, POP)
This may sound technical, but don’t worry—it only takes 5 minutes, and we’ll provide a step-by-step guide.
For a basic understanding, here’s what these protocols do:
SMTP (Simple Mail Transfer Protocol): Handles sending emails from your server to the recipient's inbox. Proper setup ensures smooth email delivery.
IMAP (Internet Message Access Protocol) & POP (Post Office Protocol): Both retrieve emails from the server.
IMAP allows syncing across multiple devices (recommended for outreach).
POP downloads emails to a single device.
1️⃣ If you're using Outlook, go to: 🔗 admin.microsoft.com
2️⃣ Click on your account name, and the settings page will appear.
3️⃣ Select “Mail” to configure the necessary settings.

4️⃣ When you are in the E-mail tab you can click on “Manage email apps”

5️⃣ Now you can simply enable all the protocols “IMAP”, “POP”, and “SMTP” and press the “Save” button.

Great! You're almost ready to start your warm-up, just one last step to go! 🚀
✅ Implementing SPF, DKIM, and DMARC
Now the final step to enhancing your deliverability is to implement SPF, DKIM, and DMARC records. Again, this might feel daunting, but don’t worry it will only take around 15 minutes and with our tutorial every step is very detailed.
We have provided a full tutorial here to implement these records: SPF, DKIM, DMARC Tutorial
To provide a quick overview again we have outlined the use of each record:
SPF (Sender Policy Framework): Specifies which mail servers are permitted to send emails on behalf of your domain. Setting up an SPF record helps prevent spammers from sending messages that appear to come from your domain.
DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails, allowing recipients to verify that the email was indeed sent from your domain and hasn't been tampered with during transit.
DMARC (Domain-based Message Authentication, Reporting, and Conformance): Builds upon SPF and DKIM by specifying how receivers should handle emails that fail authentication and provides a mechanism for reporting fraudulent emails.
🎯 Conclusion
Starting with cold email outreach with a new domain requires careful planning and execution. By selecting an appropriate domain, gradually warming it up, configuring essential email protocols, and implementing authentication measures, you can maximize deliverability and protect your primary domain's reputation.
