Send an email from a markdown file with YAML frontmatter

One-file workflow: reads metadata (to, subject, optional cc, bcc, thread_id, attachments, labels, from) from the YAML frontmatter at the top of a markdown draft and dispatches to mc_send(). Lets callers keep each logical email in a single .md file instead of splitting subject, body, and recipients across a paired .R script.

Usage

mc_md_send(path, to_self = FALSE, override = list())

Arguments

path: Path to the markdown draft (with YAML frontmatter).
to_self: Logical. If TRUE, address the message to the sender and drop cc, bcc and thread_id, so it reaches nobody else. Default FALSE. Caps the recipients; does not stop the send.
override: Named list of arguments to override frontmatter values at call time (e.g. list(subject = "New subject")). Overrides merge after frontmatter, so override wins.

Value

Invisibly returns whatever mc_send() returns.

Details

Sends. To produce a Gmail draft for review instead, use mc_md_draft().

Required frontmatter fields: to, subject. Missing either triggers an error that names the file.

Examples

if (FALSE) { # \dontrun{
mc_md_send("communications/20260413_cindy_newsletter_draft.md")

# Check the rendering in a real inbox without involving anyone else
mc_md_send("communications/20260413_cindy_newsletter_draft.md",
           to_self = TRUE)
} # }
