I had this problem for a while. I found that actually opening the emails helped. I wasn’t doing so because the subject and visible first line were often all I needed to see. I had to check my spam folder for about a week and keep reclassifying AlertDC emails to my Inbox, but it seems to have worked.

I tried adding a filter the other day to never mark as spam any email that has “Alert DC” in the subject or text. It seems to be working, but we’ll see. Seems like they randomly get sent to spam, like others said, if I delete without reading for a while. Occasionally I go through and mark as not spam but it always happens again.

I am assuming this is happening to you in Gmail. I was having this same problem and managed to fix it. Go to your ‘settings’ page and click on the ‘filter’ tab. From there create a new filter and in the ‘from’ field add ‘@alert.ema.dc.gov’. On the next page select ‘never mark as spam’. This should fix your problem. It’s been working for me since I set it up a few days ago.
