What is a Direct Mail API?

Direct mail API enables you to integrate your CRM or other marketing platforms with the direct mail software to automate direct mail processes.

What are the benefits of Direct Mail API?

PostGrid’s API has the following benefits:

Complete Automation

With our API, you can automatically input data in real-time, which will get triggered and send direct mail automatically to the intended recipient as per the information you’ve fed. It helps you line up the event-based direct mail and minimize the possibility of forgetting to mail your important clients and customers, meanwhile affecting your relationship.  Plus, automated direct mail adds value to the customer’s purchase cycle and enhances your business’s credibility.

Ensures Safety

Safety is our primary concern, so we ensure that every transaction keeps the confidentiality of the information and data thus shared, and it’s secured with its integrity intact. By incorporating API, we make sure that every communication happens with a secure API key, which is required to authenticate the process. Every direct mail request made through API will need a key to guarantee data safety and security.

Build a relationship with customers

With automation taking care of the repetitive tasks and giving you the freedom to personalize your direct mail, we’ll help you forge and foster long-term relationships with clients and customers. API automation leads to the consistent delivery of direct mail, which increases customer lifetime value. Regular mail will keep your customers updated with the offerings and discounts, which they might enquire about, and will result in building a good relationship with them.

Boosts Customer Engagement

With trigger-based automated direct mail, PostGrid will ensure that your target customer receives the notification of your products and services as and when it is required. It’ll make the customer feel valued, and they’ll engage with your brand more consistently. Furthermore, it’ll help you build a strong and loyal customer base that will eventually become your brand ambassador.

Proactive Approach

With PostGrid’s API automation, you can launch a direct mail advertising campaign after thorough testing, which will help you identify and resolve any problem before you plan on executing. It’ll save significant time, money, and resources that you might end up putting into before getting campaign reports.

Enrich Customer Experience

Direct mail can increase your brand awareness, engagement, and customer retention, but the desired impact gets hampered by manual processing. With no manual job increasing the probability of errors and delay, our PostGrid API automation will provide a seamless experience to your customer with the set trigger delivery of relevant direct mail at the right time.

Facilitates Easy Tracking

Using direct mail marketing campaigns with CRM integration empowers your business to track real-time progress from your dashboard. Further, it provides you with the needed analytics and data insights on your campaign performance and helps you understand customer shopping behaviour to strategize better.

Complete Control

With direct mail automation, you no longer have to rely on the staff or wait for them to be done coordinating with different teams and completing their respective tasks. You have full control of the direct mail campaign, which, depending upon the requirement, you can carry out at a scale that you want to with API facilitating automating.  


API automation might sound like an expensive investment. But, if you calculate the resources, time, money, and employee potential you’ll invest when choosing in-house services, you’ll find that an API-based direct mail marketing solution provider is a better and cheaper option available. That’s why it’s always a cost-effective decision to choose an API-based platform for long-term benefits.
