not receiving mail from a gmail sender

Okay I will try this again. My issue is I do not receive mail from someone using a gmail,com account. The last gmail mail I received was on 8-28-2025. I send mail from my ''[email removed]''@optonline.net account to a gmail address and I don't get a response. I have a known and trusted person send me mail from there gmail process and do not receive it. I spend a lot of time with optonline help and the say there mail process is working fine. It was suggested that my browser could be the problem, so I am coming to you to correct the issue. I had sent this same request to you yesterday but can not find any it anywhere in your system. So I will try again. Richard Everett ''[email removed]''@optonline.net ''[phone number removed]''
