Domain verification in Amazon SES is now based onDomainKeys Identified Mail (DKIM), an email authentication standard that receiving mail servers use to validate an email’s authenticity. Configuring DKIM in your domain’s DNS settings confirms to SES that you’re the identity owner, eliminating the need for TXT records. Domain identities that were verified using TXT records do not need to be reverified; however, we still recommend enabling DKIM signatures to enhance the deliverability of your mail with DKIM-compliant email providers.
