To ensure that Zoho is authorized to send emails on your behalf, you need to add _zoho.com_ in your SPF record. SPF is a DNS-based filtering mechanism, more aptly known as an email authentication standard that mail gateways use to identify legitimate mail servers.

Steps to Setup SPF for Zoho Mail

• Open your DNS registrar’s account 

• Navigate to the domain for which you want to modify/add your SPF record

• If you already have an SPF record for that domain: 

In case you are using Zoho Campaign, 

Add the following include mechanism to your pre-existing SPF record: 

include:zcsend.net

In case you are using Zoho Mail, 

Add the following include mechanism to your pre-existing SPF record: 

include:spf.zoho.eu or, include:zoho.in

Kindly consult with Zoho support in order to have better clarity on which include statement you should add for Zoho. Your modified SPF record will look something like this: 

v=spf1 include:_spf.google.com include:zoho.in -all 

Note: Make sure you have only one SPF record configured for your domain, and you are adding IP and include mechanisms for third-party email services and applications into the same SPF record. If you publish multiple SPF records in your DNS, SPF will be invalidated. 

• If you don’t have an SPF record for your domain, simply add a TXT record with the value: 

v=spf1 include:zoho.in -all
