Hi Saurabh,

There may be a chance of duplication of the target and may be the typology was not configured properly.

Hi venue,

We already applied dedup on email, no chance to get duplicate records. And the target coming from back only one. And all the typologies are applied properly.

Thanks

Hi Saurabh,

Did you add any seed address in the target and there is chance to lead this duplication.

Can you check it again in the target and make sure whether you have added or not.

Hi Saurabh,

First confirm that if the delivery had only one Broadlog for the recipient in question.

If yes, then search for the email address in the MTA child logs. If there is more than one occurrence, then review the status of each attempt.

In most cases, it is either attempted multiple times as we received bounce message back in every try, until we succeeded last.

Or if it is only sent once per the MTA Child logs as well, then from the actual deliveries pick a sample URL (tracked) from each message, and compare the delivery ID from the parameters list of all, and see if it is actually same.

If the message was "Technically" sent only once from Campaign, then the problem is usually at ISP's end.

In some rare occasions, it happens that even though we receive only one success response, ISP could have delivered the message more than once.

If the MTA child logs indicate multiple sends, under all other normal conditions, then it may need further investigation.

Hi Saurab,

If the targeted domain is outlook there is a chance to get the duplicates due to cookies.

if you use 'andriod' email apps - sometimes emails will be loaded twice. for example Outlook is one of them.

it is not an issue with sender domain at all.
