🔐 SPF, DKIM & DMARC Setup for Coldbean (Namecheap + Google Workspace)

To ensure your cold emails reach inboxes (not spam folders), setting up proper domain authentication is critical. If your domain is hosted on Namecheap and you’re using Google Workspace (formerly G Suite) for email, this guide will walk you through setting up SPF, DKIM, and DMARC records — all essential for high deliverability with Coldbean.

Why Domain Authentication Matters for Coldbean

Cold email platforms like Coldbean require trusted domain configurations to:

• Protect your brand from spoofing

• Improve inbox placement (avoid spam)

• Build long-term sender reputation

Step-by-Step Setup Instructions

1. Add Your Domain to Google Workspace

Before you configure DNS records:

1. Log in to your Google Admin Console: admin.google.com

2. Navigate to Domains > Manage domains

3. Click on Add a Domain and follow the instructions to verify it

4. Google will ask you to add a TXT record in Namecheap to prove ownership

Google will guide you with the exact value to use in Namecheap for domain verification.

2. Activate Gmail for Your Domain

To enable Gmail:

1. Go to Apps > Google Workspace > Gmail

2. Follow instructions to activate Gmail service

3. Update your MX records in Namecheap to:

   Priority: 1 | ASPMX.L.GOOGLE.COM
   Priority: 5 | ALT1.ASPMX.L.GOOGLE.COM
   Priority: 5 | ALT2.ASPMX.L.GOOGLE.COM
   Priority: 10 | ALT3.ASPMX.L.GOOGLE.COM
   Priority: 10 | ALT4.ASPMX.L.GOOGLE.COM
   

It may take a few hours for DNS propagation to complete.

3. Set Up SPF (Sender Policy Framework)

SPF helps mail servers verify that Coldbean is allowed to send emails on your behalf.

1. Log in to your Namecheap dashboard

2. Go to Domain List > Manage > Advanced DNS

3. Under Host Records, click “Add New Record”:

   Type: TXT
   Host: @
   Value: v=spf1 include:_spf.google.com ~all
   TTL: Automatic
   

4. Configure DKIM (DomainKeys Identified Mail)

DKIM adds a cryptographic signature to prove your email hasn’t been tampered with.

1. Go to your Google Admin Console

2. Navigate to Apps > Google Workspace > Gmail > Authenticate Email

3. Select your domain and click Generate New Record

4. Google will generate a DKIM TXT record that looks like:

   Name (Host): google._domainkey
   Value: [DKIM key provided by Google]
   

5. Copy this to Namecheap as:

   Type: TXT
   Host: google._domainkey
   Value: (Paste the DKIM key)
   TTL: Automatic
   

Then, go back to Google Admin and click “Start Authentication.”

5. Add a DMARC Record (Optional but Recommended)

DMARC protects your domain from spoofing and phishing.

1. In Namecheap, add a new TXT record:

   Type: TXT
   Host: _dmarc
   Value: v=DMARC1; p=none; rua=mailto:team@coldbean.ai
   TTL: Automatic
   

You can change p=none to p=quarantine or p=reject later based on how strict you want DMARC enforcement.

You can generate advanced DMARC records using a tool like dmarcian.
