A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or other. The most popular use of a TXT record is to add your website to an Internet search engine or to an analytics platform, which provides info about the traffic to your website. Creating this type of a record functions as proof that you're the domain address owner and they will provide the content that you should include as the value when you set up the record. Another purpose of a TXT record is to verify that an email message is sent by the Internet domain owner and from a trusted hosting server - this is the so-called SPF protection, that prevents any electronic address created under your domain name to be forged and unauthorized people to send out junk mail making it appear like it was mailed from your own mailbox. You may include any other information which you want to be associated with your domain address in a TXT record as well.
