Emails Not Arriving?

Not Receiving Our Emails? Whitelist Us.

Automated system emails often end up accidentally being sent to the spam folder in your email, or being filtered and not arriving at all. To avoid this, “whitelisting” the sender's domain and/or email address will prevent this from happening.

To whitelist an email address just means you add them to your approved senders list. This tells your email client/program that you know this sender and trust them, which will keep emails from being filtered on going into the junk/spam folder.

But this is different for each different email program and service. Below is some guidance, but with there being so many email programs and versions these steps may not be exact, but should point you in the right direction. Googling "how to whitelist an email in yahoo 2020", "how to whitelist an email in att 2020", "how to whitelist an email in office 365 2020", etc, will help find instructions for your specific program and version.

Whitelisting Email in Other Email Applications & Webmail Services

If you use a Web mail system or email application adding the “From” address to your “address book”, “safe list”, “whitelist” or “contact list” will usually work.

Also, check your “spam”, “bulk” or “junk” folder. If the email is there look for a way to indicate that it is not spam. For example by selecting the email and clicking a button such as “Not Spam” or “Not Junk”.

If you are still having trouble please submit a support ticket describing which email service or client (with software version number) you are using and any other relevant information and we will send the specific steps for your email program.
