Prevent Emails Being Marked as Spam (SPF Records)
The best way to prevent emails from being marked as spam is by taking preventative measures and adding an SPF record to your DNS settings. If you do not have access to your DNS Zone details, you will need to work with your local IT source that manages this information to update these details.
There are two IP addresses that we use to send emails from your ChMS: 75.2.115.101 and 99.83.174.65. In an SPF record, these would appear formatted: ip4:75.2.115.101 ip4:99.83.174.65.
Emails can also be sent through Sendgrid and Forms emails send through Mandrill. These should also be included in the SPF records for your domain.

SPF Record Setup:
SPF records are typically setup as a TXT type record in your DNS settings. If you have multiple SPF records to add, it's often necessary to place these in a single TXT record at the root of your domain. So, you have an example to look at, we've included a screenshot below that shows the setup of both Gsuite & Office365 SPF records (in green) along with other common records that could exist in a single TXT file (in red).
Notes:
(1) Depending on your provider, the syntax may differ. In the example above, the setup screen required quotes before and after each entry. This may be different for your domain hosting provider.
(2) We offer the above only as an example. Our team is not certified for DNS setup and cannot add these records for you. If you don't feel confident to manage your own DNN or need advanced troubleshooting, you will need to contact an IT professional to assist.
