Pasting the SPF and DKIM records in Squarespace

To add the SPF TXT record for your domain, follow these steps:

1. Log in to your Squarespace account.
   
2. Open Advanced DNS Settings for the domain.
   
3. Scroll down to Custom Records.
   
4. In the Record field of a blank row, select TXT from the drop-down.
   
5. Enter "@" in the Host field.

   Example: v=spf1 include:zcsend.net include:sender.zohobooks.com~ all

Note: A sender domain can have only one SPF TXT record. We recommend not to add a new record if you already have one. If you have an existing SPF TXT record,

1. Locate the record you added.
   
2. To the existing record details, add "include:zcsend.net" after "v=spf1". (Example: v=spf1 include:zcsend.net include:spf.zylker.com ~all)
   
3. Click ADD and then click Save to confirm.
   

If you are using Zoho Marketing Automation from the regions below, add the respective TXT value instead of include:zcsend.net.

1. EU region - include:eu.zcsend.net
   
2. India - include:zcsend.in
   
3. China - include:zcsend.net.cn

5. In the Host field, enter the DKIM host name displayed in the SPF/DKIM Setup screen.  (Example: 2232._domainkey)

7. Copy the DKIM TXT record displayed in the SPF/DKIM Setup screen in your Zoho Marketing Automation account. Paste it in the Data field.
   
8. Click Add to save the DKIM record.

Note:

1. If your DNS has already mentioned the domain name, enter the domain key alone in the Host Name field.
