For best results across Gmail, Outlook and Apple Mail the HTML should be email-safe: table-based layout around 600px wide, inline styles, PNG/JPG/GIF images in <img> tags (not SVG or CSS backgrounds), web-safe font fallbacks, and alt text on images. Returns the template id; follow up with send_template_test to send a preview.

Send16 can refuse a send. 429 SEND_RAMP_LIMIT: new and free workspaces have hourly and daily sending limits while they build reputation; the error details give the window, the limit and how many remain. Tell the user how many can go now and that the rest can go once the window resets (or after upgrading), and do not split the send or retry in a loop to get around it. 403 SENDING_PAUSED: sending from the workspace is paused while the Send16 team reviews it. Nothing was sent. Tell the user to check the workspace owner's email or contact support, and do not retry. 422 MESSAGE_NEEDS_REVIEW: the content looked like it might be impersonating a government agency, bank, toll operator or delivery company, so it was held and not sent.

• send_email≈ 872 tokens

  Send a transactional email through Send16. Provide `html`, `text`, or both (text-only is fine for OTPs/receipts/alerts). `from_email` must belong to a domain that is verified in the workspace; call `whoami` for the account and `list_domains` to see which senders are allowed; a send from an unverified domain returns a clear error, not a silent failure. For a zero-setup first send, use from_email `onboarding@send16.com`; the sandbox sender delivers with no DNS, but only to your own account email. Before calling, confirm with the user: show them the recipients (or the recipient count), the sender and the subject, and wait for a clear yes. Send16 can refuse a send. 429 SEND_RAMP_LIMIT: new and free workspaces have hourly and daily sending limits while they build reputation; the error details give the window, the limit and how many remain.

Nothing was sent. Tell the user to check the workspace owner's email or contact support, and do not retry. 422 MESSAGE_NEEDS_REVIEW: the content looked like it might be impersonating a government agency, bank, toll operator or delivery company, so it was held and not sent. Tell the user it is held for review and they can contact support if it is legitimate. Do not reword it and try again; repeated flags pause the workspace.
