The receiving server can compare the email sender’s actual IP address to the list in the SPF record. The SPF record is a TXT record that lists the IP addresses approved by the domain owner. Sender Policy Framework (SPF) is an email authentication standard developed by AOL that allows you to list all the IP addresses that are authorized to send email on behalf of your domain. For more information about how DKIM works, see DKIM Records Explained. The DKIM record is a TXT record that stores the DKIM public key. With DKIM implemented, the sending email server adds a cryptographic signature to your emails' headers. DKIMĭomainKeys Identified Mail (DKIM) is an authentication method that uses asymmetric encryption to sign and verify your email. DMARC is encouraged, but not a requirement for email authentication. DKIM, SPF and DMARC are all implemented in part by setting TXT records on your domain. When working with an email provider such as Twilio SendGrid, you should be aware of three types of email authentication: DomainKeys Identified Mail (DKIM), Sender Policy Framework (SPF) and Domain-based Message Authentication, Reporting & Conformance (DMARC). ![]() ![]() These providers allow you to set and remove DNS entries for your domain. Popular DNS providers include DNSimple, GoDaddy, Rackspace, and Cloudflare, but there are many others. For example, your domain may have an A record pointing to the IP address of your web server and CNAME records pointing to the cloud service that handles your email.ĭNS records are managed using your DNS provider or host. A single domain may have many records of varying types. However, some records, such as CNAME records, link a domain to another domain or "host." Other records, such as TXT records, allow a domain owner to store text information about the domain. An A record points a domain directly to an IP address where requested resources can be found. It resolves domains humans can remember, like, to IP addresses that belong to specific computers. DNS is a naming system for domains on the internet. DNS and Domain SetupĪs mentioned earlier, Domain Name System (DNS) records are essential to verifying which email servers are allowed to send email on behalf of your domain. If you wish to continue with Domain Authentication setup, skip ahead to the setup instructions. However, you do not need to become an email deliverability expert to send email with Twilio SendGrid. Having a high level understanding of the following terms will help as you learn more about email deliverability. Both receiving email servers and human recipients will be more likely to trust the legitimacy of your messages, which means you're more likely to reach an inbox than a spam folder.Your recipients will no longer see "via " beside the from address of your messages.Once you have completed Domain Authentication by following the instructions on this page: Verify that you have given the sending email server permission to send email on behalf of the domain.ĭomain Authentication, formerly known as Domain Whitelabel, is Twilio SendGrid's process for domain setup and setting the DNS entries that grant us permission to send email on your behalf.Communicate to receiving email servers that you own the domain the email was sent from.When sending email, you must set Domain Name System (DNS) records on the domain to: If your organization uses a different DMARC policy, Twilio SendGrid recommends you keep that policy in place as any valid DMARC record meets these requirements. These inbox providers will temporarily block email that does not meet the new requirements beginning February 2024 and reject this mail beginning April 2024. By following the steps below and adding this to the records hosted by your DNS provider, your organization will be able to meet the DMARC requirement set by Gmail and Yahoo!. In December 2023, SendGrid added a basic Domain-based Message Authentication, Reporting & Conformance (DMARC) record to the DNS records page in the console. If you're less familiar with DNS or email-specific DNS records, the following sections will help you understand why Domain Authentication is necessary and how it helps protect the reputation of your domain when sending email. ![]() If you're already familiar with Domain Name System (DNS) records, you may want to skip to the setup instructions. Domain setup is a crucial step in sending affective email campaigns. This page guides you through Domain Authentication setup. It's important to note that while this documentation discusses Twilio SendGrid here, the requirements and best practices for setting up domains and ensuring email deliverability are applicable to all reputable email delivery services. This page provides insights into Twilio SendGrid's Domain Authentication process, focusing on domain setup and the verification of sending email servers' legitimacy through DNS entries.
