A TXT record is text in free, human-readable form, which is associated with an Internet domain as a DNS record for one purpose or another. The most frequent use of a TXT record is to add your site to an online search engine or to an analytics platform, that offers details about the web traffic to your website. Creating such a record works as proof 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 use of a TXT record is to validate that an e-mail message is sent by the domain owner and from a reliable server - this is the so-called SPF security, that prevents any electronic address created under your domain to be forged and unauthorized individuals to send junk e-mail making it look like it was mailed from your own mailbox. You may include any other info you want to be associated with your domain in a TXT record as well.
