This guide walks through the fastest way to add recipients and launch a mail campaign from an existing card template.
Step 1: Start from your template
Log in to your LettrLabs account.
Select the template you want to use.
Click Create Order, give your order a name, then click Create.
Everything from your template carries over to the new order. Click Next until you reach the recipient step.
Step 2: Add your recipients
You have two options:
Upload a CSV spreadsheet — drag and drop your file, then map your file's columns to the correct fields (for example, First Name → First Name). For any field you want left blank, choose "Select a column" from the dropdown.
Add a single recipient — manually enter First Name, Last Name, and Address, then click Save.
Step 3: Review your addresses
You'll see a list of your uploaded addresses. Double-check that everything is formatted correctly before continuing.
Step 4: Proof your mailer
Review the preview of your mail piece — layout and content — then check the box to approve the proofs.
Step 5: Checkout
Complete your order at the checkout screen as usual.
