Notification emails going to my junk folder for some unknown reason

i have created other forms in the past and had this problem. You guys fixed it. Please fix this one as well. 

We apologize for the inconvenience.

If you use a custom sender, it is recommended to switch to one of our standard senders or your own SMTP sender instead. When you use a custom sender the emails are being sent from our servers on behalf of your domain which might be considered as not safe by some email providers.

If you are not getting emails to some address, please check it against our bounce list first.
