This almost exacerbated a misunderstanding between some of my family members. I recently worked to get my sister back in touch with her grandfather, took some coaxing on both sides, and then grandpa decided to email my sister, who never responded, so he tried one more time and then concluded that she didn't really want to talk to him. She uses gmail and his messages were dropping into her junk folder. She almost exclusively uses her phone for her gmail access, so she never saw the messages. Since gmail doesn't give anything like SpamAssassin headers for messages, there's nothing I can do to troubleshoot this aside from trial-and-error.
