### **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 Handler
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: **\_dmarc**
Value: **v=DMARC1; p=none;**
\[Your Domain\*\] is your sending domain without the brackets. Do not add this manually to the Hostname for the Bounce Handler or DKIM. Your DNS provider does this automatically.
#### What to do once you have actioned the above
Click Account on the left hand side and then select **Configuration** and you'll be on the **Email Authentication** page**.**
Enter your sending domain (just the domain, not your sending email address) in the box provided and click **Submit**
****
Then click **Verify.** If everything has been installed correctly for the sending domain you will see the following.
Any elements that remain orange will need to be checked with your IT team or whoever controls your domains DNS. You can click the "Get Started PDF" that will download a PDF with these instructions. You can pass that to your IT team.
Sending email campaigns without full email authentication run the risk of not been delivered.
Once your authentication has been set up, the sending domain will then be preset in the NewZapp sending wizard so you only need to enter the first half of the address. Below is an example from one of our customers for how this will look.
You'll also see this confirmation on the start screen every time you log in.
### **What if my email address isn't authenticated?**
If you try to send an email through NewZapp with an email address that isn't authenticated. NewZapp will update your From Address to be sent from the @newzapp.co.uk email domain. Our domain is authenticated and so your emails will then be delivered.
Your address will be updated to be
**"no-reply-\[company name set in NewZapp\]@newzapp.co.uk"**.
The screenshot above was taken from our NewZapp Communications account, so the email appears in an inbox like this.
If you have safe senders set up in NewZapp you would normally be able to select the From Address from a preset list in a drop down box, however if your domain is not authenticated this drop down box won't be present and your From Address will be set in the format specified above.
**What if I cannot authenticate my domain?**
No problem, reach out to your account manager today and we can go through some options for you that will ensure your email campaigns are getting their maximum deliverability.
