We've been getting regular calls and emails saying that people are suddenly no longer receiving the church emails.

Services like Gmail, Outlook.com and Yahoo! Mail regularly update their programs to better protect you from unwanted or malicious email such as phishing, scams and spam. In this case, they are mistaking email that you want for email that you don’t want. Usually, they will send these mistaken "spam" emails to your junk folder.
If you ask your email provider to unblock or "whitelist" an email address, email from that address will be more likely to get through.
Follow the link below to learn how to "whitelist" emails from the church on Outlook, Gmail, or Yahoo! Mail. Emails from the church will usually come from office@fumcmarblefalls.com or an individual staff member's email.
