Email Authentication

What is Email Authentication

Email authentication (or email validation) is the process used to verify the source and legitimacy of your email message. As you may have seen in news articles online, full authentication is vital for email delivery to many email providers like Outlook, Gmail and Yahoo who require full delivery authentication and alignment as standard.


Email Authentication helps providers verify the origin of a message: whether it comes from a trustworthy source or has been faked or forged by spammers, scammers, and spoofers pretending to be someone they are not.

Setting up DKIM, SPF and DMARC records for your NewZapp Account.

Bounce Handling

Please follow these steps to add a DNS record to point to our Bounce Handler for your sending domain. This process won't impact your corporate or organizational email.
Please add a CNAME DNS Record with the following detail:

Type: CNAME
Hostname: bounced.[Your Domain*]
Value: bounced.newzapp.co.uk

SPF

When sending through NewZapp you need to add an SPF to your full sending domain in order to achieve Full Alignment of DMARC, SPF & DKIM. Please add one of the following details:

Add include:_spf.newzapp.co.uk  to your existing record.

If you do not have an SPF record then create one as follows:
Type: TXT
Hostname:
Value: v=spf1 include:_spf.newzapp.co.uk -all

DKIM

To set up DKIM on your account, you will need to create three new CNAME DNS records for the sending domain as follows:

Type: CNAME
Hostname: nz-k1._domainkey.[Your Domain*]
Value: nz-k1.dkim.newzapp.co.uk

Type: CNAME
Hostname: nz-k2._domainkey.[Your Domain*]
Value: nz-k2.dkim.newzapp.co.uk

Type: CNAME
Hostname: nz-k3._domainkey.[Your Domain*]
Value: nz-k3.dkim.newzapp.co.uk

DMARC

DMARC is used to enhance email security by helping prevent email spoofing and phishing attacks. Please add a TXT DNS Record with the following detail

Type: TXT
Hostname: @
Value: v=DMARC1; p=none;
 
[Your Domain*] is your sending domain without the brackets, https:// or www. For example "https://www.bbc.co.uk"  would be "bbc.co.uk" Creating a hostname nz-k1._domainkey.bbc.co.uk

What to do once you have actioned the above


Once you have implemented the changes to your DNS above you must contact us on support@newzapp.com so we can verify your authentication. Once we have confirmed full alignment you will be able to view the status of your authentication at any time under Account Settings.
