I have two different email clients I use Cox Business and the other is gmail business account. I have never been able to send out mass emails from the gmail account and mass only being about 175 users. Until this week I could send out mass email from the cox account. I get an error message from gmail that says Sending of the message failed. Your message has too many recipients. ToomanyRecipientserror 5614622812f47-3e661190b86sm3130092b6e.7 - gsmtp. The other error message I am getting from cox says. Sending of the message failed. Recipient temporarily rejected - OXSUS003_403 -https://postmaster-oxsus.vadesecure.com/outbound_error_codes/#_405. However I can send a mass email to the same recipients from my personal email from cox using thunderbird and have no issues. I would love any suggestions you may have. I would really love to solely use my gmail account and move away from the cox business account if we can get this working.

have you tried the 'mail merge' addon?

I tried the Mail Merge it didn't work. I found out that I can use the mail merge when logged into the gmail account on the web and then send the mass text out. But when I tried to send it through Thunderbird it comes back saying too many recipients.

Was the error message from within Thunderbird, or from the email host?
