![]() To comply with DMARC, messages must be authenticated through either SPF or DKIM, or both. It specifies how your domain handles suspicious emails. DMARCĭomain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol that uses SPF and DKIM to detect email spoofing. This signature can be validated against a cryptographic key you will add to your DNS records, to prove legitimacy of the emails. Think of it as a digital signature that is added to the headers of email messages. DKIM’s advantage is that it can survive forwarding, which makes it superior to SPF and a foundation for securing your email.īy setting DKIM on your DNS (Domain Name System) server, you are certifying email recipients (and ISPs) that it’s really you who is sending the emails that they receive. ![]() It allows ISPs to check that an email was indeed sent and authorized by the owner of that domain. DKIMĭKIM (Domain Keys Identified Mail) is another email authentication method and was created for the same goal as SPF. In practical terms, you add a record to your DNS specifying which computers can send emails from your domain. This helps preventing email spoofing (when spammers send emails from domains that they don’t own and make the message appear from someone or somewhere other than the actual source). SPF stands for Sender Policy Framework and works by strictly specifying the number of allowed domain IPs that can send emails from your domains. There are 3 protocols that you should use to confirm ownership of domains and ensure optimal email deliverability. So, making sure your account is authenticated before start sending emails is a crucial step to ensure optimal deliverability of your emails with Amazon SES. But SMTP does not provide any authentication by itself. In summary, email authentication helps prevent messages your organization sends from being flagged as spam.Īmazon SES uses the SMTP (Simple Mail Transfer Protocol) to send email. In some cases, ISPs refuse to forward email that is not authenticated. If they are not, it’s very likely that they will end up on the recipients’ spam folders. Most ISPs that forward email traffic check if emails being sent are authenticated and thus, legitimate. If emails are not authenticated, ISPs (Internet Service Providers) cannot identify if the emails being sent are coming from spammers or genuine senders. What is email authenticationĮmail authentication is how email senders can verify that they are the owner of the account that they are sending from. ![]() In this post, we will run you through the types of authentication and process of authenticating your accounts – domains or single email addresses – in Amazon SES, so you can start sending emails with high deliverability. From security to deliverability, you can protect your brand from fraud and help your emails successfully reach the inbox. Although not mandatory in Amazon SES, email authentication is highly recommended and has many benefits. ![]()
