Unfortunately my order arrived damaged but after emailing the issue over to the company I received a quick response from Jess who was able to fix the problem in minutes, thanks so much Jess, fantastic customer service, will definitely be ordering from this company again.
I recently made a purchase from postal packaging which is the first time I had purchased from the company, and I couldn’t be happier with the entire experience. From start to finish, everything was seamless, professional, and incredibly customer-focused. The items I ordered arrived quickly, was exactly as described, and exceeded my expectations in both quality and value. But what truly set this company apart was the amazing customer service. When I had a few questions after placing my order, their team responded promptly, kindly, and with a level of detail that showed they genuinely care about their customers. I highly recommend postal packaging to anyone looking for top-quality products and truly exceptional service. I’ll definitely be a returning customer! Thank you!
Really easy process to order some custom printed envelopes, James was so helpful and answered all my questions. The envelopes arrived on time and are really great quality, wouldn’t hesitate to use this company again!
