It is a best practice to configure SPF authentication (also known as Sender Policy Framework) with your domain provider before sending any emails. Once configured, SPF authentication allows mail servers to authenticate emails that originate from your domain. It enhances the deliverability of your messages, too!
If your want to configure Campaign Monitor to send emails on behalf of your organization, follow the simple steps provided below.
Creating an SPF Record for Campaign Monitor
Login to your DNS management console
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for Campaign Monitor will have the following syntax:
yourdomain.com TXT v=spf1 include:_spf.createsend.com -all
Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using Campaign Monitor. If you do have an existing SPF record in your DNS, you need to modify it to include Campaign Monitor, as shown below:
Previous SPF record: v=spf1 include:spf.zoho.com -all
Modified SPF record: v=spf1 include:spf.zoho.com include:_spf.createsend.com -all
Now you need to wait for 48-72 hours to allow your DNS to process the changes
