Expert’s Assistant chat

Customer: I am sending a group email from Yahoo/cox email. I keep getting mail failures for several gmail accounts. I do not get them from other email accounts.
JA: I understand you’re having trouble with group emails sent from your Yahoo/Cox email, specifically getting mail failures when sending to several Gmail accounts. How long have you been experiencing this issue?
Customer: A few weeks. I have been sending these people emails for a few years.
JA: Thank you for clarifying that this has been happening for a few weeks after years of successful emailing. Could you let me know if you’re accessing your Yahoo/Cox email through a web browser, an app, or an email client (like Outlook or Apple Mail)?
Customer: I am accessing it through the yahoo app which inhave always used.
JA: Thanks for letting me know you’re using the Yahoo app as usual. Could you share if you’re seeing any specific error messages or codes in the mail failure notices you receive?
Customer: This is the messages I get. 550: 5.7.1 [34.2.80.19 12] Gmail has detected that this message is likely 5.7.1 unsolicited mail. To reduce the amount of spam sent to Gmail, this 5.7.1 message has been blocked. For more information, go to 5.7.1 https://support.google.com/mail/?p=UnsolicitedMessageError 5a478bee46e88-30f0bbc931asi30349792eec.58 – gsmtp
JA: I see, you’re receiving a 550: 5.7.1 error indicating Gmail is blocking your messages as potential unsolicited mail. Have you made any recent changes to the content or subject line of your group emails?
Customer: no changes to any of these contacts.
JA: Understood, no changes have been made to your contacts or the content of your emails. Have you tried sending a test email to just one of the affected Gmail addresses, rather than the whole group?
Customer: Yes, some people get them individually and some I still get a failure
JA: Thank you for testing individual emails and letting me know that some still result in failures. Could you tell me approximately how many Gmail addresses are affected versus how many are receiving your emails successfully?
Customer: I sent a test message for 8 gmail accounts and got 3 failures. However, one person actually got the Indifidual and group message.
JA: Thanks for sharing those details about the test results and the mixed delivery outcomes. Have any of the affected Gmail recipients reported finding your emails in their spam or junk folders, or are the messages not arriving at all?
Customer: The message have not gotten to spam.
JA: Thank you for sharing the details. The Email Technician will help with your Gmail delivery issues from Yahoo app. Here’s what I’ll tell them: <ul><li>You get mail failures sending group emails to Gmail.</li><li>You have not changed your email content or contacts.</li></ul> Is there anything else the Email Technician should know before I connect you?
Customer: I don’t think so. Hopefully the technician will solve this issue. Really don’t understand why it just started to happen when I have been sending these people group emails for several years.
JA: Thank you for providing the details. And, how would you like to connect with the Technician – phone call or online chat? Under the circumstances, I recommend a phone call.
