Load your CSV contact list, write a personalised template with merge fields, and send to hundreds of recipients in one click. No third-party service, no monthly fee.
Built for small businesses, community managers, and anyone who needs to send personalised emails at scale — without a monthly SaaS bill.
Drop in any CSV file with your contact list. Headers are auto-detected — map your columns to merge fields like {{first_name}}, {{email}}, {{company}} in seconds.
Write your email once using merge tags. Every recipient gets a personalised message with their own name, company, or any other field from your CSV.
Before sending, preview exactly how each email will look for any contact in your list. Catch mistakes before they reach hundreds of inboxes.
Connects to your existing email account via SMTP or Gmail OAuth. No new email address needed — send from the account your recipients already recognise.
Real-time progress bar shows sent, pending, and error counts. A full send log is saved locally so you always have a record of who was contacted and when.
Configurable send delay between emails keeps you within your email provider's limits and reduces the chance of landing in spam folders.
Click "Load CSV" or drag and drop your contact file onto the app. Any CSV with an email column works — the app auto-detects your headers and lets you map them to merge fields.
Works with any CSV — no format restrictionsEnter your SMTP credentials or connect via Gmail OAuth. Your credentials are stored encrypted locally — they're never sent anywhere outside your own email server.
Compose your email in the built-in editor. Use {{first_name}}, {{company}}, or any column from your CSV as merge tags. The editor shows a live character count and highlights your merge fields.
Scroll through your recipient list and see exactly how each personalised email will look. Make any last-minute edits before committing to the full send.
Hit Send and watch the real-time progress bar. Sent, pending, and any error counts update live. You can pause and resume the send at any time.
Configurable delay keeps you inbox-safeAfter sending, a full log is saved locally with timestamp, recipient, and status for every email. Export it to CSV for your records or to track follow-ups.
