See the `params` section in the check endpoint and note that HTML can be provided for the `message` section.
You can use our template editor to design the message if you like, and then copy the HTML from the "Raw Data" and place it into the "message" parameter.

Setup can take anywhere from a few hours to a few days, depending on requirements.

Please ensure that your headers for the CSV match that of the sample CSV which can be found in the upload contacts dialog box. Also, the "Country" column expects country code and not the country name.

It means that the Country column in your data is incorrectly formatted. To resolve this issue, ensure that all country entries use the ISO 3166 Alpha-2 two-letter country codes.
The ISO format for country codes can be found online at https://www.iso.org/obp/ui/#search

If you you sending letterParameters via JSON, then you'll want to structure the merge variables as an object:
{
"from": "CONTACT_ID_HERE",
"to": "CONTACT_ID_HERE",
"mergeVariables": { "french": "YOUR VARIABLE DATA HERE" },
"template": "TEMPLATE_ID",
}

To create live orders, you must be in live mode. Orders created in test mode will not be transferred to live mode. Test mode orders exist so that you can become familiar with the process and integration of creating orders.
Once you are ready to send live orders, you can follow the same process as you did when creating test orders, except you will be in live mode. Test mode contacts and templates will not be available in live mode.
If you wish to use a template you created in test mode in live mode, you can copy it over. To do so, select the desired template from the dashboard template section and click the "Copy to Live Mode" button.
Once you have a template to use in live mode, you can start sending live orders just as you did in test mode.

Look for the "Cancellation" field in the Raw Data. This field provides the specific reason why the order was canceled.

It means that your template contains content in the designated address area reserved for stamping the recipient or sender addresses.
To ensure your letters are processed correctly, you can do any of the following options - Remove Content from the Address Region
Edit your template to eliminate any text or images from the designated address area and follow the design guidelines
- Insert a Blank Page for Addresses
This will print a separate blank page for the addresses, allowing your actual letter content to appear on the following page without any overlap.
You can also use Double-Sided Printing with a Blank Front Page, So the front side will be a blank page containing the addresses, and the back side will display your letter content.

The most likely cause is an issue with the sender's address. To resolve this, you should:
- Verify and Correct the Sender's Address: Ensure that the sender's address information is accurate and properly formatted.
- Force the Sender's Contact Verified Status: If the address is correct but issues persist, you may need to mark the sender's contact as verified to bypass address validation errors.

By default, all mail is sent as First Class or the quickest non-express postage available in the destination country. You can opt for a lower postage fee by selecting Standard Class from the 'Mailing Class' dropdown menu.
You can also learn more about the available mailing classes here.

USA
- First Class: 1 to 3 business days. Typically used for transactional mail like invoices or bills.
- Standard Class: 2 to 3 weeks nationally. Best for marketing mail, requiring a minimum of 200 pieces.

Canada
- Lettermail: 2 to 4 business days depending on distance.
- Personalized Mail: 3 to 8 business days, with a minimum of 100 items of the same collateral type.

Express mailing is a special service to expedite delivery. In most cases, your mail will be delivered within 1-3 business days.

Yes, we support Registered, Certified Mail and Certified Mail with Return Receipt. You can learn more here.

Tracking primarily depends on the mailing class you choose and the volume of mailings you send out.
For mailings within the US, you can utilize IMB (Intelligent Mail Barcode) tracking provided by USPS. You can learn more about how to track on the dashboard, or via the API.

Completed
This status indicates that your letter has been processed and handed over to the mail carrier. It is an estimate based on the time elapsed since the order was handled.
Delivered
A more accurate status that confirms the letter has been delivered to the recipient.
For certified letters, this status relies on the carrierTracking information provided by USPS.
For regular letters with IMB status, "Delivered" is set two days after the "out_for_delivery" scan event.

IMB status for orders depends entirely on USPS scanning the mailings. USPS scans only a portion of the mail—theoretically about 40%.
We update all the orders with the IMB information within 5-7 days after the printers have handed off the orders to the USPS and we receive the IMB codes from the printer.

- For mailings with an imbStatus attribute, we change the order status to "delivered" two days after we receive the "out_for_delivery" scan event since it is very likely that the order has been delivered after this time.
- For letters without imbStatus, unfortunately, USPS does not provides us with a "delivered" scan event so "out_for_delivery" is the last status we receive from USPS, meaning this status will not change even after your letter has been delivered.
The only exception for this is when USPS provides us with a "returned_to_sender" scan event. In this case, we indicate that the letter has been returned.

Tracking details will be available within 2 business days SLA.

Tracking numbers are only available in live mode after an order has been assigned one. To access the tracking number:

1. Decode the Webhook Body: Ensure you decode the webhook payload correctly.
2. Retrieve the Tracking Number: Access the tracking number using data.trackingNumber from the decoded JWT.

If you're not seeing the trackingNumber key, verify that the order has been processed in live mode and that the webhook is correctly set up to handle live events.

You can perform an advanced search in the Web Dashboard by using JSON formatting to filter results based on a keyword and creation date
The following example searches for completed orders with the description "test" created on May 28, 2024, and sorts them by the most recent first

{
"description": "test",
"status": "completed",
"createdAt": {
"$gte": "2024-05-01T00:00:00.00Z",
"$lte": "2024-05-31T23:59:59.00Z"
},
"sort": {
"createdAt": "desc"
}
}

Yes, we provide built-in tracking for your mailing campaigns using QR Tracking and Personalized URLs (PURLs). These tools allow you to monitor and analyze how recipients interact with your mailings, helping you measure campaign effectiveness.

The Expiry Duration determines how long the URL generated by the tracker remains valid.
You can modify the expiry duration of your tracker to extend how long the QR Code links remain active.
Each new order creates a unique URL that follows the tracker’s expiry settings. That being said, there is no need to create new trackers for each order; simply adjust the expiry settings as needed.
