01 · Connect your SMTP
Bring your own Gmail app password or custom SMTP. A successful connection test is required before sending.
02 · One list, up to 10,000
Import CSV or TXT. Each person receives a separate message. The current list locks new imports until it finishes or you explicitly delete it.
03 · Close the tab. Keep sending.
When the background sender is connected, it holds the active job in RAM. No recipient lists, attachments, passwords, or message bodies are written to our database or files. Your browser retains only a random session token.
Completed jobs are cleared automatically. Paused jobs and idle connections expire after 24 hours. A backend restart loses unfinished jobs. Return from the same browser to see status; a popup can only appear while the page is open.
Your provider is still your provider.
Your SMTP provider and recipients may retain emails. SMTP acceptance does not prove inbox delivery. A connection failure pauses sending; an uncertain delivery is never automatically retried.
