March 30, 2017 | 1 Comment Amazon updated its Buyer-Seller Messaging system on March 28, 2017, to allow shoppers to opt out of unsolicited emails sent from third-party merchants. You can still email shoppers asking for reviews and feedback, though. Want to make sure you don’t email a buyer who has opted out again? Now using ZonMaster’s Bulk Order Blocker you can paste in as many Amazon Order Numbers as you like and we’ll make sure – in one fell swoop! – that those customers no longer get emails from you. This solution is not ideal (as you still have to gather the order numbers) – it’s a stop-gap until we can implement a fully automatic system. If you have customer email addresses you can use ZonMaster’s Bulk Blacklist tool (which we’ve had since day 1). That let’s you paste in email addresses and we’ll stop them from getting any emails in the future.
