Our Customers Say It Best

We were in the middle of a super-complicated move and way down on our priority list were sending welcome letters, postcards, etc. Our team needed all of them but just didn't have the time to stay on top of the delivery times as we should. PostGrid made tracking easy through their API. Besides doing an excellent job, PostGrid delivered them the day before our deadline. They made sure everything ran smoothly for us.

Managing Director Of Operations

PostGrid integration has given our team the capability to connect with prospect data in real-time, saving us hours of manual effort as we were operating a team of 5 employees to manage the workload. Additionally, the platform provided us with reliable letters sending capability to increase customer return engagements.

Assistant Chief Information Officer

We started working with PostGrid 6 months ago and so far we have found that their print & mail technology and services are very reliable. The API platform gave us capabilities related to route mailing, which ensured savings on postage. Also, their print price, standalone, mailing and address verification service are the best that we have found around.

Chief Operating Officer

PostGrid has handled all our print material needs exquisitely. They have not only assisted us with letters, cheques and mailers but also helped us with address accuracy for timely delivery. Their team is professional, cordial, and responsive to our requirements and deadlines. Our teams often receive compliments related to the quality of our printing materials. The credit goes to PostGrid's excellence and attention to every detail.

Fulfillment Team Lead

This API has turned out to be a great asset. We started off with 4000 mailings for 3 months and never had any downtime. I requested an increase in the sending limits, and it was given to me in 10 minutes! I also have used PostGrid to verify our mailing lists. It’s been great for us, and customer support is very reliable.
