It seems like you've helped a lot of people with this, but I haven't found any instructions on how to fix it myself.  Can you help?

Hello Starla2088,

 

Thanks for your message. The issue was caused by an incorrect SPF record. I have updated the record, and you should be able to send to Gmail again.
