IXP > Email > Verify Domain

Hello Webmaster,

Please implement the following 4 changes to your website’s DNS servers so that the Investor Experience (IX) Email module can deliver emails successfully. Please contact friends@6ix.com and your Account Manager if you need any assistance, as well as to notify them once the changes have been implemented, as an additional final step is required on our end to activate the module.

1. SPF

SPF stands for “Sender Policy Framework”. An SPF record is in place to identify which mail servers are authorized to send mail for a given domain. It is used to prevent spammers from sending mail with fraudulent From addresses in that domain.

Though many DNS editors allow for the creation of an SPF record, the SPF record must be entered as a TXT record in your domain’s DNS settings to create a TXT record. Enter:

Type: TXT

Host/Name: @ (This means that the record is pointed at your own domain. Some editors will require the “@” symbol, some will require you to enter your own domain, and others will not let you enter anything. Every DNS Editor is different – you may need to contact your hosting provider for information on how to enter this record correctly)

Value: v=spf1 a mx include:6ix.com ~all

SPF tips: Check to see if there are any other SPF records in your domain’s DNS. There can only be one SPF record per domain, so if there is an existing record just add “include:6ix.com” to that record. Make sure you remove the quotes.

For example, if your domain already has the record: v=spf1 a mx include:_spf.google.com ~all, then you would just add: include:6ix.com

The final record would look like this: v=spf1 a mx include:_spf.google.com include:6ix.com ~all


DKIM stands for “DomainKeys Identified Mail”. They allow receiving servers to confirm that mail coming from a domain is authorized by the domain’s administrators.

Create a TXT record.


Type: TXT

Host/Name: api._domainkey

Value: k=rsa;t=s;p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCbmGbQMzYeMvxwtNQoXN0waGYaciuKx8mtMh5czguT4EZlJXuCt6V+l56mmt3t68FEX5JJ0q4ijG71BGoFRkl87uJi7LrQt1ZZmZCvrEII0YO4mp8sDLXC8g1aUAoi8TJgxq2MJqCaMyj5kAm3Fdy2tzftPCV/lbdiJqmBnWKjtwIDAQAB

TIP: DNS settings can have as many DKIM records as needed.
In some DNS settings, the Host/Name field may require you to enter “api._domainkey.yourdomain.com”, replacing your domain with your actual domain.

3. Tracking

The 6ix Investor Experience (IX) Platform Email module “tracks” opens, clicks, unsubscribes, etc. To do that we must rewrite links and use web pages. Setting up a “tracking domain” brands these rewritten links and pages with tracking parameters.

Create a CNAME record. Enter:

Type: cName

Host/Name: tracking

Value: email.6ix.com


We strongly recommend using a DMARC Generator – it will help you create DMARC record suited for your domain.

Domain-based Message Authentication, Reporting & Conformance is an email authentication protocol that is built on top of SPF and DKIM protocols. SPF and DKIM are prerequisites of DMARC and must be in place before setting up a DMARC policy.

A DMARC policy allows a sender to indicate that their emails are signed by SPF and DKIM and tells a receiver what to do if neither of those authentication methods passes – such as junk or bounce the email. DMARC removes the guesswork from the receiver’s handling of these failed emails, limiting or eliminating the user’s exposure to potentially fraudulent & harmful emails.

DMARC also provides a way for the email receiver to report back to the sender about emails that pass and/or fail DMARC evaluation.

Note there is no specific configuration needed besides ensuring that your SPF and DKIM are both valid. Further, a DMARC policy on your domain(s) will affect all of your email sending from that domain (not just the mail you are sending through Email) so you need to ensure you are using SPF and DKIM for all your email delivery.

Option 1- Setup your DMARC policy with a simple, most common DMARC record. You will not receive any reports with this setup.

Type: TXT

Host/Name: _dmarc

Value: v=DMARC1;p=none;
