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 other. The most frequent use of a TXT record is to add your web site to an Internet search engine or to an analytics platform, that offers information about the targeted traffic to your web site. Creating such a record serves as proof that you are the domain owner and they'll supply the content you need to include as the value when you create the record. Another application of a TXT record is to verify that an email message is sent by the Internet domain owner and from a trusted hosting server - this is the so-called SPF protection, that helps prevent any electronic address set up under your domain name to be forged and unauthorized individuals to send junk mail making it appear like it was mailed from your own mailbox. You could add any other info that you would like to be associated with your domain in a TXT record as well.
