Our Customers Say It Best

“We have been using PostGrid for a few months. It works with our CRM, the software interface, efficiency, automation, and integration with no issues. Their support team is quick with resolution and their web portal is easy to access and transparent in retrieving transactions and analyzing weekly & monthly sending limits.”
Chief Technology Officer

“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 to us and customer support is very reliable.”
Vice President Of Engineering

“We wanted a low-cost, easy-to-understand, and easy-to-use direct mail platform. Finally, PostGrid took all my worries in terms of snail mail. The pricing is very reasonable! There is almost no delay in the SLA’s commitment, and it is exciting to watch automation in action. Easy to build and maintain the mailing lists of our patients. Not to forget, reports can be generated, and a block editor can be used too!”
Director Of Operations

“We were looking for a solution to outsource and automate our process of mailing welcome letters to our customers. Previously had 2 dedicated people printing the postage label, stamping it manually and stuffing the mail and dropping it off at the postal office. It was very inefficient and could have caused major compliance issues. PostGrid helped us eliminate the entire manual process with their automation and API solution, now sending all mails smoothly.”
Director of IT and Operations

“Very straightforward, fast, and reliable address standardization API. We collect address data from multiple patients, clinical records, and providers and attempt to combine them into one. Addresses are often redundant or formatted differently in this process, which is our biggest challenge. PostGrid makes it easy for us to solve both of these problems simply by appending PostGrid to our datasets.”
