Authorizing Domain and setting up DNS records

What is domain authentication?

Domain authentication, shows email providers that SendGrid has your permission to send emails on your behalf. To give TextP2P permission, you point DNS entries from your DNS provider (like GoDaddy, Rackspace, or Cloudflare) to TextP2P.

Even though this is a small change from your recipient's perspective, this change has a huge positive impact on your reputation as a sender and your email deliverability. Email service providers distrust messages that don't have domain authentication set up because they can not be sure that the message comes from you. Explicitly stating that it comes from you increases your reputation with email service providers which makes it much less likely that they will filter your mail and not allow it get to your recipient's inbox, which increases your deliverability. You are also explicitly showing your recipients that this email comes from you, so they are less likely to mark your mail as spam.

Key terminology

DNS

DNS stands for Domain Name System. This is a naming system for domains on the internet. When SendGrid refers to your DNS, we are talking about your domain name that you want to send emails from, or that you want to link images from. When we talk about your DNS provider, we are talking about the service that hosts your domain name. For example, GoDaddy, Rackspace, or Cloudflare.

CNAME

The CNAME record creates an alias for subdomain.yourdomain.com and points to sendgrid.net. The CNAME is needed for our click and open tracking features in order for those statistics to be routed back to your SendGrid account. This will also be what your messages are signed by, so your recipients will be able to see what you have chosen for your CNAME. You set up the CNAME files that SendGrid provides with your DNS host.
