A calmer way through the backlog

The forwarding workflow
Gmail should have shipped.

01

Select naturally.

Use the Gmail checkboxes already in your inbox. ThreadRelay picks up the threads you selected—no importing, uploading, or rebuilding a list.

02

Review once.

See the source account, destination, and exact thread count before anything leaves your inbox.

03

Let the queue run.

ThreadRelay spaces Gmail API calls, retries safe operations, and lets you pause or resume without starting over.

Private by design

Your messages don’t detour through our server.

ThreadRelay processes your selected messages locally and sends them through Google’s official Gmail API. Our billing service sees your subscription status—not your email bodies.
