Send Letter

To send a letter through PostGrid, you need to provide both sender and recipient information, along with details about the mailing itself.

Sender and Recipient requirements

For letters, both Sender and Recipient Information are required.

You have options to fill in First Name, Last Name, and Company Name. At least one combination is required, either First Name & Last Name or Company Name.

Next, you need to complete the address information, which includes Address Line 1, Address Line 2, City, State, Postal Code, and Country Code .

Please note that the Country Code must be provided in the two-character ISO31661 Alpha-2 format

Mailing requirements

In addition to sender and recipient details, you must also define the specifics of your mailing.

Description field is used internally to help you identify the letter later.

Template Source determines how your letter is generated. You can choose any of the following options:

• HTML: You can enter the letter template HTML code in the Template Value.
• PDF URL: You can put the publicly accessible PDF URL in the Template Value
• PostGrid Template ID: You can put the Template ID of a template you've created in your PostGrid account. You can learn more about PostGrid Template Editor here.

Also, please note that your template should follow PostGrid Design Guidelines for print readiness, which you can find here.

You will also need to choose the Address Placement, which controls whether the recipient’s address is printed on the first page of your letter or on a separate cover page automatically added to the document.

PostGrid also allows you to configure printing preferences. You can select whether the letter is printed single-sided or double-sided, in color or black and white, or Perforate First Page

For delivery, you must choose one of the available Mailing Classes. You can learn more about different mailing classes here.

If you have already set up a Return Envelope with PostGrid, you can include it in your letter by adding the Return Envelope ID. You can learn more about Return Envelope here.

Personalized letters

Finally, PostGrid supports personalization by letting you add Merge Variables to your template. You can map the variables you have defined in your template to actual data fields in your scenario. Up to ten key-value pairs can be configured for this purpose, enabling highly tailored content for each recipient.
