EnterYourHours.com sends emails to your clients on your behalf. These emails will have your email address as the "From", which can cause emails servers to erroneously flag these emails as spam.
To help prevent this from happening, your domain or email administrator can include the EnterYourHours.com SPF zone in your domain's SPF record. Your administrator will need to make this change in your domain's DNS system. By using this include, your domain will know that our servers are "eligible" to send emails. Also, using the include in this way is preferable to an IP address, because mail server IP addresses can change in the future.
Your can let your administrator know to include the EnterYourHours.com SPF record in your domain's SPF as follows:
include:enteryourhours.com
