Claude Code sends a reviewed 16-recipient campaign

Tri Vo uses Claude Code to build a real sixteen-recipient invitation campaign, with two account managers and recipient-specific merge fields. The project grows from a test email into a recipient CSV, manager registry, HTML and plain-text templates, previews, dry-run mode and send script.

Testing catches problems the code alone did not reveal. Embedded base64 images cause Gmail clipping and broken graphics; attachment references replace them. Vietnamese accented names display incorrectly until the template declares UTF-8. Vo also checks that each rendered recipient version contains only the correct account manager's contact details, and flags uncertain honorifics instead of assuming every name can be classified.

Only after previews, a test to his own inbox and a full dry run does Vo give the explicit instruction to send all sixteen. A later API query corrects the agent's earlier mistaken claim that opened and clicked status is unavailable. The resulting perfect open figure is not proof of human interest, because corporate security scanning can affect it. The useful result is a reviewed merge-send pipeline and completed small campaign, not an independently measured sales gain. The public starter kit uses fictional sandbox data rather than exposing the real recipients.
