A TXT record is text in free, human-readable form, which is associated with a domain name as a DNS record for one purpose or another. The most common use of a TXT record is to add your site to an Internet search engine or to an analytics platform, that offers info about the targeted traffic to your site. Creating this type of a record serves as verification that you are the domain owner and they'll supply the content that you need to include as the value when you set up the record. Another application of a TXT record is to validate that an email message is sent by the domain address owner and from a reliable hosting server - this is the so-called SPF protection, which prevents any electronic address set up under your domain 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 info that you'd like to be associated with your domain in a TXT record as well.
