To ensure that Zoho is authorized to send emails on your behalf, you need to add _zoho.com_ to 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 a mechanism to your pre-existing SPF record:
include:zcsend.net
In case you are using Zoho Mail,
Add the following include a 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 the 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
