# Sending Domains

### Sending Domains

In email marketing, configuring a **Sending Domain** is essential for improving email deliverability and ensuring messages reach the inbox. In SenderWiz, setting up a sending domain aligns your email’s “From” address with a verified domain, which also includes adding proper DKIM, SPF, and DMARC records to establish trust with receiving email servers.

### Why You Need a Sending Domain?

Setting up a sending domain helps authenticate your emails, which increases their chances of landing in your recipients’ inboxes instead of their spam folders. It does this by:

* **Matching the From Address**: Ensures that emails appear to come directly from your domain, reinforcing brand consistency.
* **Improving Deliverability**: Properly configured domains with DKIM, SPF, and DMARC records enhance trust, making it more likely for emails to bypass spam filters.
* **Building Sender Reputation**: Authenticating your domain with DKIM and SPF helps build a good sender reputation with ISPs (Internet Service Providers), which improves your overall deliverability rates.

### Step-by-Step Guide to Setting Up a Sending Domain

Here’s how to configure a sending domain in SenderWiz:

**1. Create Your First Sending Domain**

* Go to the **Sending Domains** section in the SenderWiz dashboard.
* Click on **Create New** to add a new domain.
* Enter your domain name in the input field (e.g., `demo.com`) and click **Save Changes** to initiate the setup process.

**2. Verify DNS Records for Your Domain**

After adding your domain, SenderWiz will generate DNS records that need to be added to your domain’s DNS settings. This includes DKIM, SPF, and DMARC records.

* **DKIM Record**: The DKIM record is provided as a TXT record, which includes a unique key to authenticate your email. Copy the provided TXT record and add it to your DNS settings.
* **SPF Record**: The SPF record is a TXT record format specifying the IPs or servers authorized to send emails on behalf of your domain. This record is crucial for preventing spoofing and increasing deliverability.

{% hint style="info" %}
Make sure to replace the placeholder IPs (e.g., `192.168.0.1` and `192.168.0.2`) with your server’s actual IPs while adding the SPF record.
{% endhint %}

* **DMARC Record**: DMARC (Domain-based Message Authentication, Reporting, and Conformance) helps protect against email phishing by ensuring that both DKIM and SPF are properly aligned. Add the DMARC record as a TXT record to complete the setup.

**3. Update Your DNS Settings**

* Log in to your domain’s DNS hosting provider (e.g., GoDaddy, Cloudflare, Namecheap).
* Navigate to the DNS management section.
* Add the provided DKIM, SPF, and DMARC records exactly as shown in SenderWiz, ensuring the values match what is displayed.
* Save the changes to your DNS settings.

Please note that DNS changes can take up to 48 hours to propagate, though it often happens faster.

**4. Verify Your Domain**

Once you’ve added the DNS records, return to the SenderWiz dashboard and click **Verify DNS Records**. SenderWiz will check if the records are correctly configured.

* If verification is successful, your domain will be marked as verified and ready for use.
* If verification fails, double-check the DNS entries to ensure they are correct, and try verifying again after some time.

### Using Your Verified Sending Domain

Once verified, your sending domain is ready to use for your email campaigns. By using a verified domain:

* Your emails will appear to come from your domain’s email address, building trust with recipients.
* The DKIM and SPF authentication helps ensure email deliverability, making it more likely your messages will reach the inbox.
* The DMARC record protects your domain from phishing and spoofing attacks, improving your domain’s reputation.

### Additional Tips for Domain Setup

* **Use Consistent Domain Names**: When setting up multiple sending domains, use a consistent structure to maintain brand recognition.
* **Monitor Domain Health**: Regularly check your domain’s health and reputation to keep your email deliverability high.
* **Avoid Frequent Domain Switching**: Frequently changing domains can harm your sender reputation. Try to maintain consistency with your sending domains.

### Conclusion

Setting up a sending domain in **SenderWiz** is an essential step for any email marketing campaign. By configuring your domain with proper authentication records (DKIM, SPF, DMARC), you build trust with ISPs and improve your deliverability rates. With a verified sending domain, you can confidently send campaigns that are more likely to reach the inbox, strengthening your sender reputation and maximizing engagement.
