Email Deliverability 

Email is a significant part of communication in every business. Companies sometimes use different domains and marketing platforms to deliver the message to their recipients. In any case, it's crucial to establish an email relationship with your domain and marketing platform for a cohesive relationship between the two.

Zoho CRM provides email authentication standards that allow organizations to increase the trustworthiness of an email's origin when they choose to send emails from Zoho CRM using their domain.

It can be beneficial to get help from your web developer or whoever manages your website for the next section.

Email Authentication can be achieved in Three Simple Steps:

1. Add your companies Domain (or Sub-Domain)
2. Verify the Domain Details
3. Validate the Records

How to Authenticate Email

1. Log in to Zoho CRM 
2. Setup > Channels > Email > Email Deliverability > Email Authentication

Step 1: Add your company's domain or subdomain

Domain verification helps to ensure that the domain from which the emails being sent are authentic and trustworthy

1. Go to Setup > Channels > Email > Email Deliverability > Email Authentication.
2. In the Email Authentication tab, click + Add Domain.

Step 2: Verify Domain Details

Once you add the domain, a verification code is generated and sent to the email address that should be entered to verify the domain details. 

1. Go to the Domain and click Enter Code.
2. In the Verify Domain popup, enter the Verification code.
3. Click Verify.

The verification email is valid for 15 days; if you do not receive an email or have exhausted the validity period, you can use the Resend Mail link.

Step 3: Validate the Records

Once the domain and subdomains details are verified, you can select the two email authentication standards to validate the email source: 

2. DKIM is used to ensure that the message has not been altered in transmission. It uses public-key encryption to authenticate the email messages.
3. SPF authentication standard allows sending domains to define which IP addresses are allowed to deliver email messages on behalf of the domain.

How to Validate the Records

1. Go to the Domain and click Validate Records.
2. In the Authenticate Domain popup, copy the SPF or DKIM record code.
3. Paste the code in your DNS settings.
4. Click Validate Record once the code is added
