Sometimes email client applications (the app on our computer, tablet, or smartphone you use to check your email) moves emails to your spam folder, but often your email service provider does it first at the server level – and adding a sender to your address book is not typically enough to stop that action.
If you are having issues with our emails being sent directly to your spam folder, or are not receiving our emails at all, you'll need to correct it with your email service provider. Below are links to articles with instructions on how to do this.
Note: Some of these articles include instructions on more than one procedure, so read carefully for the correct option.
All others should check with their email service provider about “how to stop email from being filtered as spam by the server."
