In practice
Email uses it for SPF, DKIM and DMARC, and many services use one to check you control a domain. A single string is limited in length, so long values are split into chunks inside one record.
Verification and sending
Not related to verifying recipients. A verifier looks up MX records to see whether a domain can receive mail.
