A TXT (text) record is used to hold virtually any free text you want and has a hostname so that you can assign the free text to a particular hostname/zone.
However, the most common use for TXT records is to store SPF (sender policy framework) records and to prevent emails being faked to appear to have been sent from you.
To add a TXT record, log into your control panel and select your domain name under “Hosting” on the left hand side. Then, within the main control panel select the “Domains” tab and click the domain you wish to add the TXT record to.
Following this, you will need to select the “add TXT record” tab to add the details of the TXT record.
