A TXT record is text in free, human-readable form, which is associated with a domain address as a DNS record for one purpose or other. The most popular use of a TXT record is to add your web site to an Internet search engine or to an analytics platform, that offers info about the targeted traffic to your web site. Setting up such a record functions as verification that you're the domain owner and they will provide the content you need to include as the value when you create the record. Another application of a TXT record is to confirm that an email message is sent by the domain owner and from a reliable hosting server - this is the so-called SPF protection, that helps prevent any electronic address created under your domain to be forged and unauthorized individuals to send out unsolicited 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.
