Lob + Blockspring Integration

Lob and Blockspring have partnered to offer the simple sending of postcards, letters, and checks without the need to write any code. Instantly link your Blockspring account with Lob and send API requests from spreadsheets. Leverage your existing spreadsheet models, workflows and datasets for powerful targeted outreach. For example, you can send postcards to a waiting list, send letters for invoicing, or send custom promotions to retain customers.

Step 1: Connect your Lob and Blockspring Accounts

Head over to Lob on Blockspring’s website, and paste in your Lob API key found in your dashboard settings.

The Test API Key will not send out any mail, but can be used for testing content. If you use the Live API Key, mail will be sent out. You will need to add a payment method before sending any Live API requests.

Step 2: Select a Template

Step 4: Send Mail

In this example, we'll be sending postcards using the Blockspring postcard template. You can fill out or import addresses into the rows of the template as shown below.

You can add your content (HTML/PDF/PNG/JPEG) into the cells labeled front (front side of postcard) and back (back side of postcard).
