Are Your Email Newsletters Properly Authenticated to Maximize Delivery?

· Email,All In One CRM,Help

Email newsletters and email marketing operate using a seemingly simple, but realistically complex technology we all know as "email." The most important goal of the email marketing is to end up in the inbox of your recipients. However, achieving the inbox is a constantly evolving challenge.

In recent months we've noticed that mass (and even single) emails sent to recipients using Outlook Exchange are increasingly ending up in the Junk folder if they are not properly authenticated.

How to Authenticate your Emails

There are three primary components to authenticating email you send: SPF, DKIM, and white-labeled links.


SPF stands for "Sender Policy Framework" and it shows the exchange server of your email recipients that you have authorized the system you are using to send email, to send your email. Whether you are using Gmail, Outlook, or VipeCloud, setting up your SPF can noticeably affect your ability to end up in the inbox.

To setup your SPF, you (or your IT person) need to login to the service you use to manage your DNS (aka the service you used to buy your domain name from). This can be GoDaddy, Namecheap, Yahoo!, or any number of domain hosts.

In your DNS, add a TXT (text) record with a value for the SPF. Here is a sample SPF value: "v=spf1 a mx​ ~all"

This SPF value authorizes everyone with an email address at your company to send emails from Gmail or Outlook. The Sendgrid part is for VipeCloud.


DKIM stands for "DomainKeys Identified Mail" and it is a separate email authenticator than SPF. DKIM uses a key to add a digital signature to your message header. You can setup your DKIM similar to your SPF by adding a TXT record to your DNS. However, setting up the DKIM is more complex than the SPF record. If you'd like to setup DKIM for G-Suite, for example, you can view their help article here.

An alternative solution, which VipeCloud employs, is to achieve this signature by adding a few CNAMEs to your DNS. A CNAME is a different type of DNS record than a TXT record, though CNAME and TXT records are managed in the same place.

Whitelabeled Links

If you send emails directly through Gmail or Outlook with links that you don't care to track if clicked, you don't have to worry about this section.

However, if you use a third party to send emails (like VipeCloud) and/or like to know if your links are clicked (like VipeCloud offers), then it's important that your links have the same domain as your email. For example, if you are sending from your links should all be to and not This is called "whitelabeling."

At VipeCloud we utilize Sendgrid to send our customers' mass emails. You can whitelabel your links by adding a couple more records to your DNS. They are called CNAME records and will make your links look like "" which will match the domain of the link to your email address.
