AI-Generated Review

What is mass-sender?

Mass-sender is a JavaScript tool for sending bulk personalized emails via Gmail or Outlook using OAuth—no passwords stored, just refresh tokens. Load contacts from CSV or XLSX with columns for email, subject, and body, then fire off campaigns with configurable delays to dodge rate limits, dry-run previews, CC options, and auto-attachments from a files folder. It solves the pain of manual outreach or clunky bulk email services for devs needing a quick, local bulk email sender.

Why is it gaining traction?

Stands out with dead-simple OAuth setup via browser flows that save tokens to .env, skipping endless API console fiddling. CLI flags like --dry-run, --delay, and --limit make testing bulk email marketing software safe and paced, while XLSX support handles real spreadsheets. As a free bulk email sender, it beats paid services for low-volume github mass email sender tasks without vendor lock-in.

Who should use this?

Sales engineers blasting cold emails to leads from exported CRMs, indie hackers notifying beta users, or GitHub maintainers doing bulk email for team invites and issue updates. Perfect for solo devs or small teams hitting bulk email thresholds on personal accounts, especially with dry-runs for bulk email verification before live sends.

Verdict

Grab it for personal bulk email sender free needs—solid docs and CLI make it dead easy, but 13 stars and 0.9% credibility score signal low maturity and zero tests, so stick to small batches under Gmail/Outlook limits. Fine prototype, not production fleet. (187 words)
