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 website to an online search engine or to an analytics platform, which 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 name owner and they'll supply the content you should include as the value when you set up the record. Another use of a TXT record is to verify that an e mail message is sent by the domain owner and from a trusted server - this is the so-called SPF protection, which prevents any electronic address created under your domain to be forged and unauthorized individuals to send out spam making it appear like it was mailed from your own mailbox. You could add any other info that you'd like to be associated with your domain address in a TXT record as well.
