Frequently Asked Questions
How Different Industries Can Use Our Solution?
Our Print & Mail API is suitable for multiple industries, saving time, effort, and money in their offline communication efforts.
Healthcare
Healthcare and related companies must handle high volumes of medical documents, such as bills, medical statements, test reports, prescriptions, appointment reminders, discharge summaries, and other documents, with complete adherence to HIPAA regulations. Our Print & Mail solution helps them automate the entire process of producing and sending these critical communications without compromising Protected Health Information (PHI). They can also run direct mail campaigns to advertise their services and build higher credibility.
Finance
Banks and financial institutions work in a highly regulated industry. They handle physical monthly statements, tax documents, reminders, check reorders, audit notices, and regulatory disclosures. Banks, insurers, credit firms, and other financial companies can use our solution as a part of their ongoing marketing and communications strategy. It adheres to critical regulations, such as GDPR and PCI DSS, with end-to-end data encryption to protect sensitive financial data.
Retail & Ecommerce
This industry requires multiple channels to promote its products and stores. Direct mail is hugely beneficial in reducing cart abandonment, running promotional campaigns, and building a loyal customer base. Our solution provides native integrations for e-commerce platforms and marketing automation tools to bridge the gap between online and offline marketing strategies. They can send event-triggered mailpieces using the automation capabilities of our API.
Nonprofits
Nonprofits and charitable organizations need donors and volunteers to achieve their mission and goals. Direct mail is still a reliable method to reach people in a local neighborhood to gather support and build credibility. Automated direct mail and USPS help these organizations receive additional discounts by qualifying for non-profit mail. Everything, from printing to sorting to mailing, is automated, so they don't need to hire a dedicated staff to manage manual work.
Education
Schools and universities also need an offline communication channel to send prospectuses, parent communications, event invitations, degrees, certifications, and other important information. They don't have enough resources to design, print, package, and mail these mailers manually. Our Print & Mail API can free up their schedules and save overhead costs, helping them to focus on other critical operations.
Public Relations
PR firms and marketing agencies need multiple channels to maintain their clients' brand reputations. Direct mail automation is the only way to give them an advantage over competitors in the offline communication space. These firms can use our built-in tools to focus on content, design, campaign timings, and other factors to receive a higher number of responses. We help them unify their offline communication tasks via a single dashboard.
What collateral formats are supported by PostGrid’s Print & Mail API?
Clients use our solution to send marketing, transactional, and compliance communication mailings with automation.
Letters
We provide letter envelopes in various sizes depending on your specific requirements. This format is highly personal and ideal for communication and marketing purposes. However, the postal rates will be slightly higher for bigger sizes. Use our drag-and-drop editor to personalize every aspect of your letters.
Postcards
It is the most cost-effective direct mail format, ideal for marketing and engagement campaigns. We help our clients to send postcards of different sizes, starting from 6 x 4 to 9 x 6 to 11 x 6. It makes your mailpiece design visually appealing and communicates the message in the fewest words.
Bills and Statements
You can use our letter templates and native integrations to generate bills, invoices, and statements with real-time data synchronization. Variable Data Printing (VDP) helps you dynamically input financial data into your collaterals with precision.
Checks
Our Print & Mail API's network allows businesses to send different types of checks safely, accurately, and on time. It uses MICR toner on checks for added security and provides tracking mechanisms to ensure deliverability. You can also add your branding elements to spread awareness and make your checks more attractive.
Bi-fold Self Mailers
You can use this option to send flyers with dimensions of 8.5 x 11 inches. It's the perfect option for businesses to inform their audiences about discounts, products, offers, or other important announcements. Being bi-folded helps you attract people with a unique flyer design with branded graphics and colors.
