The Lob connector for Muse

Real mail, sent like an API call.

The Lob connector sends physical mail programmatically: postcards, letters, and direct-mail batches, with address verification and delivery tracking. It turns "we should mail our best customers" into a done task.

Every send costs real postage, so nothing goes out without your explicit approval — Muse drafts the batch, you approve the spend.

What Muse can do with Lob

Send postcards and letters to verified addresses
Verify mailing addresses before sending
Track mailpiece delivery status
Run direct-mail batches to customer lists

Try asking

“Send a thank-you postcard to our top 20 customers.”
“Verify this mailing address before we send anything.”
“What’s the delivery status of last week’s batch?”

Safety notes

Every send costs real postage — explicit approval required per batch.
Addresses are verified before mail goes out to avoid wasted spend.
This is a community-built connector. Review its permissions before connecting.
