Mailform (Preview)

The easiest way to print and mail letters and postcards: USPS First Class, Certified, Priority and Priority Express Mail.

This connector is available in the following products and regions:

The Mailform connector allows flows in the Power Automate environment to send physical mail: provide a PDF proof and some print specs such as color/black and white printing or simplex/duplex printing, and Mailform will print the document to spec, stuff it in an appropriate envelope, add postage and hand it off to the USPS (and soon, FedEx) on your behalf. The connector provides a single, straightforward method to do this: you could for example have a flow that reacts to a new user signup by sending them marketing documents, or sending a customer a postcard with a coupon 30 days after their order is shipped.

Prerequisites

You will need the following to proceed:

• A Mailform account with a valid, non-zero credit account (to pay for your print and mail jobs). Sign up for free at Mailform

How to get credentials

To obtain credentials:

• Log into your Mailform account at Mailform
• Go to your Billing settings by visiting Mailform Billing
• Click the Purchase Account Credit button, and then click the $25.00 option to add the minimum amount of credit to your account.
• Complete the payment process: this will create a credit account and add credit to your account.
• Go to the API Access settings by clicking on the API ACCESS tab or visiting Mailform API Access
• Click the NEW API TOKEN button, then give the token a label (such as Power Automate Testing). While testing, you can enable test mode for this key: all API requests will be accepted and verified, but no actual mail will be sent. Test mode orders will be accepted and then immediately cancelled, and will not affect your credit balance.
• The new API token will be shown: please copy it down, as it will NOT be displayed ever again. Note that test mode API tokens can never be switched out of test mode: when you are ready to go live you will need to create a new API token.

To demonstrate the use of Mailform, we will create a flow that will send a flyer with a coupon code on my birthday. In the Power Automate editor:

1. Create a new flow by clicking the Create button.
2. Select the Scheduled Cloud Flow option.
3. Name the flow, and set the date and frequency (in this case, every 12 months on Dec 27th, 2023).
4. Click the Create button.
5. Click the plus icon and click on Add an action.
6. In the dialog, search for Mailform, then select the Prints and mails a letter or postcard using Mailform action.
7. Fill in the recipient and sender addresses.
8. Fill in the document and print specifications: first click the Advanced Parameters option and then select url, and then enter the value https://www.mailform.io/samples/sampleflyer.pdf. Then click the Advanced Parameters option and then select color, and then select Yes.
9. Click the Save button at the top of the editor, and we’re done. When the flow runs, the order will be placed within the Mailform account associated with the API key.

Known issues and limitations

• Print proofs must be less than 40 MB: if the PDF document you are mailing is more than 40 MB you will need to pre-process it to reduce the file size.
