Snail Mail - Multiple copies sent in error

I recently sent out a letter to several clients and have been informed by at least 3 clients that they got the letter 17 times! It was around the end of December - was there a problem with snail mail ? There is no indication on quickfile that I send letter many times or that luckily we have been charged for all the duplicates.

Hi @Marisana

There were a few errors with the snail mail around November/December time which were unfortunately out of our control.

I’ll check your account regarding any used credit and come back to you shortly.

[Edit]
I can see a letter there on your account, dated 29th December, all to the same client. The letters look identical - is this intentional?

Thank you - same letter should have gone to different clients ( one copy per client of same letter )

I’ll send you a private message now with some more info. Look out for a green notification in the top right hand corner.
