Sending email from a task

Send email by running the bundled Node script — do not assemble JSON in the shell.

Why this exists

Hand-rolling the send (curl -sS … -d "{… \"html\": $(echo "$HTML" | jq -R -s '.') …}") is fragile: depending on quoting/escaping it produces a malformed body, and the API used to silently deliver an empty footer-only email titled "Message from Recoup" with success:true. The model gets this wrong stochastically. This script removes shell serialization entirely.

How to send

Write the email body to a file (recommended for HTML — avoids all escaping issues):

cat > /tmp/report.html <<'HTML'
<h1>Daily Report</h1>
<p>…your real content…</p>
HTML

Send it:

node "$SKILL_DIR/scripts/send-email.mjs" \
  --subject "Daily Report — $(date '+%B %d, %Y')" \
  --html-file /tmp/report.html \
  --to owner@example.com

$SKILL_DIR is this skill's install directory (~/.agents/skills/recoup-platform-email-helper); use the absolute path to scripts/send-email.mjs.

Flags

Flag	Meaning
`--subject <s>`	Subject line (optional — the API derives one from the body if omitted).
`--html-file <path>` / `--html <s>`	HTML body. Prefer `--html-file`.
`--text-file <path>` / `--text <s>`	Plain-text body.
`--to <email>`	Recipient (repeatable). Omit to default to the account's own email ("email me this").
`--cc <email>`	CC (repeatable).
`--chat-id <id>`	Room id for the footer "continue the conversation" link.
`--dry-run`	Serialize + validate and print the payload; do not send. Use to preview.

Rules

Exactly one body is required. The script refuses to send (exit code 2) if there is no non-empty --html/--text. Never try to send an empty email.
Check the exit code. Non-zero means it did not send — read stderr and fix it; do not report success. The script prints the Resend message id on a real send.
The script reads RECOUP_API_KEY / RECOUP_ACCESS_TOKEN and RECOUP_API_BASE from the environment — these are already set in the sandbox. Never print or hard-code them.
Node only (the sandbox runtime is node22; python3 is not guaranteed). Zero dependencies.
