What is the TXT record used for?

Let’s dive deep into the TXT record. It is one of the DNS records with the most diverse purposes. You can use it in many cases as part of multiple verification mechanisms. 

What is the TXT record?

The TXT record is one of the DNS record types. Its name comes from the word text. The TXT record can contain a text message that can be orientated to people (other DNS administrators) or machines (external sources that want to verify the domain). The message, usually some code, needs to be added to the Forward DNS zone of a domain name, so other people or machines can see that the DNS administrator really has access to the zone. 

The most popular use of a TXT record is to prevent SPAM messages. Multiple TXT records can be used together to verify the domain (the origin of the emails) and to encrypt the individual messages. Without those text records, many emails can get directly into the SPAM folder of the receivers and never be opened.
