Why do you need masking?
Masking is the process of applying a custom domain as the from/reply-to address for an email campaign. It allows your brand to appear in the email header and links within the email – improving deliverability and open rates.
Each profile in Pure360 can have one custom domain mask. This domain or sub-domain is registered by you, for the sole purpose of emailing via Pure360 – it should not be used to host websites or for any other service.
We will assign each profile one of our default domain masks until you choose to set up a custom mask.
How to add your custom domain mask
1) Choose a domain for masking
For this example let’s assume your company website has the domain ‘example.com’. Your email mask can be either of the following two options:
• A brand new full domain (i.e. ‘example-news.com’, or ‘example-email.com’)
• A sub-domain of your existing domain (i.e. ‘news.example.com’, or ‘email.example.com’)
We’d suggest you don’t use prefixes or words that are likely to trigger spam filters, such as ‘offers.example.com’.
2) Set up your domain for masking
Once a domain or sub-domain has been chosen and registered with your domain provider, it will need to be pointed towards our broadcast system’s name servers
If you’d like to use NS record mapping, please raise a support ticket using the in system support widget or email email@example.com.
Alternatively if your domain provider does not allow the assignment of multiple name servers on a sub domain, you can set up the A, MX and TXT records manually. Once you have done this, contact Pure360 Support to have a DKIM key created for you. Add the DKIM key to another TXT record
|Your new domain||TTL||Record type||Value|
|300||MX||mx0.pur3.net (priority: 10)|
|300||TXT||v=spf1 include:_spf.pur3.net ~all|
|pureresponse._domainkey.news.example.com||300||TXT||( DKIM Key provided )|
|_dmarc.news.example.com||3600||TXT||v=DMARC1; p=none; rua=mailto:firstname.lastname@example.org; ruf=mailto:email@example.com; fo=1|
Please test your newly registered domain before submitting it to us – after you complete step 2, it may take up to 48 hours for the changes to propagate around the internet. If you would like any help checking the domain is working correctly, please contact our support team.
4) Contact us to add the mask to your profile
Log into the relevant profile in Pure360, then click on the ‘Support’ button on the right-hand side of the interface. Add a relevant subject line and put full information in the ticket, including:
• The domain or sub-domain you have pointed to us
• Whether you used the option of mapping the NS records or MX, A & TXT
• The full required from address including the part to the left of the @ sign record
Assuming the domain has been set up correctly, our Support team will be able to make your new domain mask available to use on your account within one working day.
DKIM (Domain Keys Identified Mail)
We support and recommend the implementation of Domain Keys Identified Mail (DKIM) signatures to maximise email deliverability. If you would like us to generate a DKIM signature for your masked domain then please ask, we’ll be happy to go through the process with you.
Can my mask be my normal company email address? No – the subdomain needs to be unique and not used for any other purpose.
Can I have a different ‘from’ address for each campaign? Changing the part of the ‘from’ address before the ‘@’ can be done by our Support team, but is not advisable to change this regularly. You may want to consider working from different profiles with different ‘from’ addresses.
Where do replies to email campaigns go? Replies are forwarded on to your specified email address. You can change this at any time via ‘My account’ – ‘Account details’ – ‘Edit details’ in Pure360.
