A TXT record is text in free, human-readable form, that's associated with a domain address as a DNS record for one purpose or other. The most widespread use of a TXT record is to add your website to a search engine or to an analytics platform, that offers info about the web traffic to your site. Setting up this sort of a record can serve as verification that you are the domain owner and they'll supply the content that you ought to include as the value when you create the record. Another purpose of a TXT record is to validate that an email message is sent by the Internet domain owner and from a reliable web server - this is the so-called SPF security, which prevents any electronic address created under your domain to be forged and unauthorized people to send out junk e-mail making it look like it was mailed from your own mailbox. You can include any other information which you want to be associated with your domain name in a TXT record as well.
