A TXT record is text in free, human-readable form, that is associated with a domain as a DNS record for one purpose or another. The most widespread use of a TXT record is to add your site to an Internet search engine or to an analytics platform, that provides info about the targeted traffic to your site. Creating this type of a record functions as confirmation that you are the Internet domain owner and they'll supply the content you need to include as the value when you create the record. Another use of a TXT record is to confirm that an email message is sent by the domain address owner and from a reliable hosting server - this is the so-called SPF security, which helps prevent any electronic address set up under your domain name to be forged and unauthorized individuals to send unsolicited mail making it look like it was mailed from your own mailbox. You can include any other info you want to be associated with your domain in a TXT record as well.
