Manage Email Signatures from the CLI — Create, List, and Attach to Sends

#cli #email #productivity #devtools

The nylas email signatures commands manage reusable email signatures stored per-grant. Create HTML signatures once, attach them to any send with a flag — no more pasting footers manually.

What email signatures do

Signatures are HTML blocks stored server-side and attached to outgoing emails via --signature-id. Create different signatures for different contexts (formal, casual, department) and switch between them per-send.

Quick Start

nylas email signatures create --name "Work" --body "<p>— Qasim<br>Staff SRE, Nylas</p>"
nylas email send --to alice@example.com --subject "Hello" --body "..." --signature-id SIG_ID

Using a signature when sending

nylas email send \

  --signature-id <sig-id>

The signature HTML is appended to the email body automatically.
