DKIM

An email authentication technique that allows the recipient to check that an email was indeed sent and authorized by the owner of that domain.

DNS (Domain Name System)

A system that lets you connect to websites by matching domain names to their corresponding IP addresses. In emailing, DNS is used to find the email server of the recipient.

DNS record (or Resource record)

Instructions for a DNS server that explains which domain names are associated to each IP address. The main DNS record types are:

  • NS (Nameserver) record: indicates which DNS server contains the DNS records.
  • MX (Mail exchange) record: specifies how email should be routed when sent to an address at your domain.

Domain (or Domain name)

Unique name that identifies a website. For example, the domain name of Brevo is brevo.com. The prefix "www" is added to some domain names but is not part of the domain. All domain names have a suffix, such as .com, .net, .org, or .fr, which helps identify the type of website the domain name represents or the location of the website.

Domain authentication
