Email delivery is a very complicated system due to all the evil spammers out there. If you want to take your email delivery one step further, there are a few simple things you can tweak in your domain's DNS that can reduce the likelihood of emails being flagged as spam.
This is an optional step and is not required. If you experience any issues with email deliverability via TourBuzz, however, you may want to take this additional step to improve your email deliverability.
We use an ESP (email service provider) named Sendgrid, and you'll need to setup 3 CNAMEs on your domain to publicly declare that your domain approves of Sendgrid sending emails on your behalf.
Step 1: Locate the 3 CNAMEs you'll need to set up
To do this, log into Tourbuzz, and click on My Account > Account Settings. Next To Email, Click on "Configure Tourbuzz.net to allow us to send email on your behalf."
Step 2: Head to your domain host, and add the 3 CNAMEs listed on this page
Each host is different and will have different steps to set this up. You need to add these CNAMEs in the same why you've added them when you set up tours.yourdomain.com.
The values on the left are the host, and the ones on the left is what the value is pointing to.
Step 3: Validate your setup
Head back to the page with your listed CNAMEs and click on "click here to re-validate DNS settings." Ensure that we are able to validate your setup. If not, double check that you've copied and pasted the information exactly, and have set up a total of 3 CNAMEs.
