A TXT record is text in free, human-readable form, that is associated with a domain name as a DNS record for one purpose or other. The most widespread use of a TXT record is to add your web site to an online search engine or to an analytics platform, that provides information about the traffic to your website. Setting up this kind of a record serves as verification that you are the domain owner and they will supply the content that you should include as the value when you create the record. Another use of a TXT record is to verify that an e-mail message is sent by the domain owner and from a reliable server - this is the so-called SPF security, which prevents any electronic address set up under your domain name to be forged and unauthorized individuals to send junk mail making it look like it was sent from your own mailbox. You could include any other information that you'd like to be associated with your domain in a TXT record as well.
