How to authenticate my domain

Domain Authentication is a mechanism that verifies the email from the point of its origin by validating the email sender. It checks emails to rule out any possibility of spamming or spoofing thereby protecting the sender's good reputation. Authenticating your domain allows for smooth transfer of emails through spam filters and into your recipient's inbox.

Domain authentication methods

SPF

This method allows you to specify the mail servers (IP addresses) which can send emails on your behalf. This can be done by publishing the TXT record in your domain's DNS settings. Learn More

DKIM

This is a more advanced method used widely by email service providers. It allows the senders to authenticate their campaigns by including a digital signature in the email header. This can be done by publishing the TXT record in your domain's DNS settings. Learn More

Domain Authentication Steps

Authenticating your domain in Zoho Campaigns is a simple four step process:
  1. Add a sender domain to your Zoho Campaigns account.
  2. To authenticate your domain, Copy SPF and DKIM record values from Zoho Campaigns.
  3. Go to your domain hosting website's Settings page to Setup SPF and DKIM records for your domain. Paste the copied record values and Publish them to the DNS servers.
  4. After your records are published, go to your Zoho Campaigns account and Verify your domain.

           Domain Authentication Steps

Step 1

Add a sender domain
  1. From the navigation toolbar, choose Settings.
  2. Select Manage Senders under Deliverability.                
  3. Click Add Sender button on the top-right corner of the screen.
  4. You can enter up to 5 sender email addresses if you want.
  5. Click Send Verification Email button to receive verification emails in the email address you have provided. 
  6. To verify your email addresses, login to your email client and open the verification email sent by Zoho Campaigns.
  7. Click the Verify your email address button in the email to complete the verification process.
  8. Once verified, you will find your sender address (Example: patricia.b@zylker.com) listed under Sender Address tab and the domain (zylker.com) listed under Domain Authentication tab.

Note: If you have not received the verification email, please check all the folders / filters in your email client. If you still don't find them, please contact support@zohocampaigns.com.

Step 2

Copy SPF and DKIM record values from Zoho Campaigns
  1. From the navigation toolbar, choose Settings.
  2. Select Domain Authentication under Deliverability. 

  3. Click Setup on the extreme right of the row.
  4. In the Setup page, click Copy button next to the text records.

Step 3

Setup SPF and DKIM records for your domain

  2. Paste the TXT record values copied from your Zoho Campaigns account in your domain's DNS settings. Click Publish.
  3. If the SPF record already exists in your domain's DNS settings, please add include:zcsend.net to the record and click Publish.

By inserting the requested records into the DNS server, the GMAIL servers reject our emails. Below is the excerpt from the report from the GMAIL server

host gmail-smtp-in.l.google.com[173.194.69.27]
    said: 550-5.7.26 This mail has been blocked because the sender is
    unauthenticated. 550-5.7.26 Gmail requires all senders to authenticate with
    either SPF or DKIM. 550-5.7.26 550-5.7.26 Authentication results:

I am also getting same issue with gmail

Dears,

I'm using NameCheap.
Cannot verify DKIM. After add the record and wait for 48 hours, I have the follow error:

Reason
There are no DKIM records in your domain DNS.

Record added:
Host Name to add
241316._domainkey.aviatorexam.com



TXT Record: k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCf7xTVBYt7h1nWFtgTTNQ7Szu9gYX1lYafRfk9Ib6IZlIA........

How can I fix it?

Hi my SPF is not getting verified. When I click on verify domain, it shows that the SPF record shown is:
google-site-verification=YHIpzNt0l80ZXGEDU0ERy-WqqVSuegvIYN1qCxUElBA

Even though I removed all other spf's from my squarespace domain, still it shows this error. I added the SPF provided by ZOHO. But all efforts went into vain.

SPF Record has a limit of 10 lookups. We cannot add every provider to SPF. Please consider to enable customers specify custom SMTP server as an option.

We added SPF and DKIM records two weeks ago and still not verified.
