Hoping someone from the Shipstation team can answer this...
We are trying to lower our shipping costs.
Our packaging qualifies as a flat which we can ship via Shipstation... But they don't offer IMb tracing.
Will Shipstation offer this in the near future? I think this is a huge opportunity for Shipstation as only a couple of vendors offer this..
We ship a whole lot of letters and flats, definitely on our wish list.
