I’m having the same issue. I get some emails, but many do not go through. This has been happening for the last couple of weeks. I have checked the spam folder and nothing is there, either.
I run a karaoke business and use WPForms Lite for song requests. I average between 80-100 emails in a 4 hours period a few nights per week. WPForms Lite worked great for two years in this aspect, until recently. Any suggestions for getting this to work would be greatly appreciated.
