SPF Include Tag Required
This outbound email provider uses an include mechanism to add this provider's IP space to your SPF. To get fully set up with SPF for this provider, you will need to take the provided “include” domain and add it to your SPF record. An example of an SPF record without an include tag is compared to one with the tag added below (the include tags added are denoted in bold).
Initial SPF Record:

v=spf1 ~all |
SPF record include added:
| HOST |
