Set Sending Domain

Setting up your sending domain is a critical first step in establishing sender credibility and improving email deliverability. When properly configured, your emails will come from your business domain.

​
Why This Matters

Build Trust

Emails from your own domain appear more professional and trustworthy to recipients.

Improve Deliverability

Emails from verified domains are less likely to be flagged as spam.

Maintain Brand Consistency

Keep your brand experience consistent across all customer touchpoints.

Enable Authentication

Allow for proper SPF, DKIM, and DMARC configuration to verify your sender identity.

Using Brew requires a business domain. Emails will always come from your own domain.

​
Subdomain vs. Root Domain

Most Email Service Providers (including Brew) strongly recommend sending from subdomains (like hey.company.com) rather than root domains (company.com). Using a subdomain:

  • Improves deliverability
  • Makes it easier to configure authentication
  • Protects your main domain’s reputation
  • Creates more recognizable sender addresses

Good subdomain options include:

  • hey.yourdomain.com
  • mail.yourdomain.com
  • updates.yourdomain.com
  • news.yourdomain.com

Important: You don’t need to create this subdomain with an A or CNAME record in your DNS settings first. Brew will provide all the DNS records you need to set up in the next step.

Remember that the subdomain you choose will appear in the “From” field of all your emails (e.g., “Your Name <name@mail.yourdomain.com>”), so pick something recognizable and professional.

​
How to Set Your Sending Domain

You can configure your sending domain either during the initial sign-up process or later through your account settings.

​
During Sign-Up

1

Enter your domain

When prompted during sign-up, enter your domain (without the https:// prefix).

This domain will show in the From field of your emails. We recommend using a subdomain like hey.domain.com to avoid spam filters.

​
From Settings

1

Navigate to Domain Settings

Go to Settings → Domain in the left navigation menu.

2

Configure your domain

Enter your domain in the “Sending domain” field (without the https:// prefix).

This domain will show in the From field of your emails. We recommend using a subdomain like hey.domain.com to avoid spam filters.

​
Additional Email Settings

While setting up your domain, you’ll also see these important settings on the same page:

​
Default Sender Name

The default sender name will appear alongside your email address in recipients’ inboxes. We recommend using a real name to build a genuine connection with your audience. This name will be used for email generation, but you can always change it directly in the editor for specific emails.

​
Company Name

Your company or organization name will be used throughout Brew for email generation, in email footers, and other places where your business identity is displayed. Brew automatically attempts to extract this from your domain during sign-up, but you should verify it’s correct.

​
Next Steps

After setting your sending domain, you’ll need to verify it by adding DNS records. This process confirms your ownership of the domain and enables authentication protocols.

Add DNS Records

Follow our guide to add the necessary DNS records to your domain to complete the verification process.

Your emails may have deliverability issues until you complete the domain verification process by adding the required DNS records. We recommend completing this setup before sending any marketing emails.
