SendLetter
ChatGPT pluginSend physical letters
SendLetter helps you prepare and send physical letters from your connected account. Check your sending setup, manage return addresses, validate address formats, calculate a price and preview your letter before deciding to send. You review the recipient, document, mailing options and total before approving a physical mailing. Sending uses your existing account balance; an eligible individual letter can instead be paid for through SendLetter’s website checkout. Follow letter status and cancel only while cancellation is still available. Supported destinations and options depend on the current service. A sandbox account simulates the workflow without charging, printing or posting. SendLetter is operated by Twilper.
