Multiple duplicate emails sent from gmail

Some of the messages I've been sending have been duplicated and sent multiple times in Gmail. For example, I send 1 message, and 1 day later I have between 5 and 30 duplicate sent messages in that email thread. I am using Gmail directly through Chrome or the iPhone Gmail App (not iphone mail app), and the problem is the same for both. The duplicates show up in the email threads. I only hit "send" once). The duplicate emails aren't sent all at once; it can span several hours (or more than a day).
 
I'm running a business using Gmail, and this is quite irritating for my clients. Please help!!!!
 
Thanks,
Alan

If the messages are all showing up separately, and have different timestamps, then something is triggering the fresh sending of the message. 

Gmail does sometimes send messages multiple times when it doesn't get an acknowledgement it can recognise from a receiving server for any reason - it will keep trying to send, which can result in your recipient seeing several copies. But that would not generate what you are seeing - you would still only have one sent message in your account. What you are seeing is a fresh send every few minutes with a different timestamp, and presumably a different message ID. 

When did this start to happen? Do the sent messages that are affected have anything at all in common? 

Was the message sent from Chrome, or via the Gmail app on the iPhone?  Have you tried turning off the phone to see if that makes any difference?  Do you have any extensions in Chrome that might be triggering this? Boomerang, for example, or any other "delayed send" script or app? 

Is the address you are sending FROM a Send Mail As address, or the actual Gmail address of the account concerned?  If it is a Send Mail As address, does it send via the Gmail servers, or another outgoing server you have access to? 

Have you tried signing out of Gmail on both devices, shutting down Chrome, clearing cache & cookies, and signing into Gmail using Incognito mode? 

Sorry for all the questions, but I have never seen exactly this error before, so need as much background as possible. There was allegedly a brief Gmail outage on 11th, which apparently caused Chrome to fail - it's possible this could be related, particularly if you haven't signed out or re-booted recently.

This started happening around Dec 5th, possibly earlier.  It has happened from both Chrome (on Mac) and Gmail App on iPhone.  I just now turned off my phone to test.  The only 2 Chrome extensions are Evernote Web Clipper and Transfer Big Files.  

This issues has happened with 2 different email accounts- my normal Gmail account as well as a "Send Mail As" address.  The "Send Mail As" address using the Gmail servers (not another outgoing server).

I have noticed that it seems to happen when replying to someone else (versus a first email message).  The thread that had 60 or so messages involved an auto-responder from the recipient.  Somehow that made things worse.  Wait a sec, scratch that.  I just looked back and found that it did happen with a message I initiated.

I just signed out of Gmail on both devices, sht down Chrome, cleared cache and cookies, and we'll see how that works.  I'll post a message if it appears to be resolved.  Please keep working on it in the meantime!

In the meantime, can we establish that these messages ARE all "fresh" messages, and all DO have different timestamps and different Message IDs?

You can find the Message IDs by opening the sent messages in Sent Mail - then from the dropdown next to the Reply button choose Show Original. That will show you the message headers, and the Message ID usually appears right above the Subject line.

Yes, I can confirm that each message was independent (separate emails at different times, unique IDs).

OK, I am going to point the Gmail team at this problem and see what they suggest.

Same here. 

Any emails sent specifically from the Gmail application are duplicated hours later.  Example, I send an email from my iPhone at 12pm CST to a group of friends.  Hours later, roughly 8:23pm CST, that same exact email shows in the Gmail thread.  

This is quite irritating for the folks on these email chains, as well as for me.

I have referred the issue to Google - in the meantime, to reduce the possibility of further duplicates, try reverting to the previous version of the Gmail iOS App.

Hey all! 

So only in alan12345's case, this is happening both on Desktop and on the iOS device. For the rest of you, its happening when you send an email from the Gmail app on iOS only. Is that correct?

I had the same problem, but on a Samsung Galaxy.
 
I found this and made the adjustments to my Mail account. There are instructions for iPhone too. So far it's worked... cross my fingers!
