# How to Improve Email Deliverability by Authenticating Your Domain with GloveBoxCRM
When you send emails from **GloveBoxCRM** using your custom domain (e.g., `you@youragency.com`), recipient mail servers (like those at Google and Microsoft) perform checks to verify that **GloveBoxCRM** is an authorized sender. By configuring specific settings within your domain's DNS, you effectively provide a digital signature that authenticates your emails as legitimate.
This domain authentication process offers several crucial benefits:
- **Improved Deliverability:** Significantly reduces the likelihood of your emails being flagged as spam, ensuring they reach the intended inbox.
- **Brand Protection:** Helps prevent unauthorized parties from impersonating your email address, safeguarding your professional reputation.
- **Increased Trust:** Your emails are perceived as more credible and professional by both receiving servers and your clients.

### **Setup-Guide: Implementing DKIM and DMARC**
This setup instructs mailbox providers that emails dispatched by **GloveBoxCRM** on your behalf are legitimate and carry your authenticated digital signature.
**Before You Begin:**
- You will require administrative access to your domain provider's DNS settings (e.g., GoDaddy, Namecheap, Cloudflare, etc.). This is where your domain's records are managed.
- Please note that DNS changes can take anywhere from a few minutes to up to 48 hours to fully propagate across the internet.
### **Step 1: Add DKIM Records**
DKIM (DomainKeys Identified Mail) acts as a cryptographic signature, verifying that an email has not been tampered with during transit and genuinely originates from your domain. Add the following two **CNAME** records to your DNS settings.
| Type | Host / Name | Value / Points To |
| --- | --- | --- |
| CNAME | `s1._domainkey.yourdomain.com` | `s1.domainkey.u10837672.wl173.sendgrid.net` |
| CNAME | `s2._domainkey.yourdomain.com` | `s2.domainkey.u10837672.wl173.sendgrid.net` |
> Important: Replace [yourdomain.com](http://yourdomain.com) with your actual domain name. For instance, if your email address is [agent@smithinsurance.com](mailto:agent@smithinsurance.com), you would use [smithinsurance.com](http://smithinsurance.com). Be aware that some DNS providers may automatically append your domain name, meaning you might only need to enter s1.\_domainkey or s2.\_domainkey into the "Host" or "Name" field. Always double-check for any typos or inadvertent extra spaces when copying these values.
### **Step 2: Add a DMARC Record**
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a policy that instructs receiving email servers on how to handle messages that fail authentication checks.
Add the following **TXT** record to your DNS settings.
| Type | Host / Name | Value / Points To |
| --- | --- | --- |
| TXT | `_dmarc.yourdomain.com` | `v=DMARC1; p=none;` |
> Important: A domain must have only one DMARC record. If you already have an existing TXT record beginning with v=DMARC1, please do not create a new one. Your existing DMARC record is sufficient for this step.
Once these records are successfully saved and have propagated, your emails sent from **GloveBoxCRM** will benefit from enhanced authentication and significantly improved deliverability.

### **Frequently Asked Questions (FAQ)**
**Q: What should I use for `yourdomain.com`?**
A: Use the domain portion of your email address. For example, if your email address is `jane.doe@bestinsuranceagency.net`, your domain is `bestinsuranceagency.net`.
**Q: My DNS provider's interface looks unfamiliar, or I'm unsure where to input these records.**
A: DNS provider interfaces vary considerably. Here are some general guidelines that may help:
- **Host/Name/Subdomain Field:** For entries like `s1._domainkey.yourdomain.com`, you typically only need to enter the subdomain portion, such as `s1._domainkey`. Your provider's system frequently appends your main domain (`.yourdomain.com`) automatically. The same principle applies to `_dmarc`.
- **Value/Points To Field:** Always copy the exact value provided in our instructions (e.g., `s1.domainkey.u10837672.wl173.sendgrid.net` or `v=DMARC1; p=none;`). Do not modify it.
- **TTL (Time To Live):** This setting dictates how long other DNS servers cache your information. It is generally safe to leave this at its default value (often 3600 seconds or 1 hour). Should you remain uncertain after reviewing these tips, please consult your DNS provider's help documentation or reach out to our support team for further guidance.
**Q: I already have an SPF record. What steps should I take?**
A: A domain is permitted to have **only one SPF record**. If you already possess a TXT record that begins with `v=spf1`, it is critical that you **update this existing record** rather than creating a new one. Introducing a second SPF record will lead to severe email delivery problems.
**To update your existing SPF record, you will need to incorporate an `include` statement provided by GloveBoxCRM.**
1. **Locate your existing SPF record.** It will typically resemble one of these formats: `v=spf1 include:spf.protection.outlook.com -all` or `v=spf1 include:_spf.google.com ~all`
2. **Contact GloveBoxCRM support at [support@gloveboxapp.com](mailto:support@gloveboxapp.com)** to request your unique SPF `include` statement. This will be an `include:` directive specific to your SendGrid configuration (e.g., `include:em1605.yourdomain.com`).
3. **Merge this `include` statement** into your existing SPF record. It should be placed before the final mechanism (e.g., `all` or `~all`).
- **Example:** If your current record is `v=spf1 include:spf.protection.outlook.com -all`
- And **GloveBoxCRM** provides you with `include:em1605.yourdomain.com`
- Your **new, merged record** would be: `v=spf1 include:spf.protection.outlook.com include:em1605.yourdomain.com -all`
Ensure there is a single space separating each `include:` statement.
If you have any uncertainties regarding the proper merging of your SPF record, please do not hesitate to contact our support team at [**support@gloveboxapp.com**](mailto:support@gloveboxapp.com) for step-by-step assistance. Correctly configuring this record is paramount for reliable email delivery.
**Q: How can I check if my DNS records have been successfully updated?**
A: After you've added your records, it can take up to 48 hours for these changes to become active across the internet. To confirm your records are live, we recommend waiting the full 48 hours and then using a free online tool such as [MXToolbox.com's CNAME Lookup](https://mxtoolbox.com/CnameLookup.aspx) or [DKIM Lookup](https://mxtoolbox.com/dkim.aspx). Simply enter the relevant record name (e.g., `s1._domainkey.yourdomain.com`) to see its current status. If your records are still not displaying correctly after 48 hours, please contact our support team at [**support@gloveboxapp.com**](mailto:support@gloveboxapp.com) for troubleshooting assistance.
