A TXT record is text in free, human-readable form, that is associated with a domain name as a DNS record for one purpose or another. The most widespread use of a TXT record is to add your web site to an online search engine or to an analytics platform, that provides information about the web traffic to your website. Setting up this type of a record can serve as verification that you are the Internet domain owner and they will provide the content that you need to include as the value when you create the record. Another purpose of a TXT record is to verify that an email message is sent by the domain address owner and from a trusted hosting server - this is the so-called SPF protection, that helps prevent any electronic address set up under your domain name to be forged and unauthorized people to send out unsolicited mail making it appear like it was mailed from your own mailbox. You may include any other info which you want to be associated with your domain name in a TXT record as well.
