1. Prepare smtp.txt

      • Open Px Mailer → SMTP Servers (or edit pxmailer/smtp.txt)
      • Add one SMTP account per line
      • Format: server|username|password|port
      • Example style: smtp.example.com|user@example.com|yourpass|587
      • Use port 465 or 587 depending on your provider

2. Set delivery options

      • Open Settings
      • Set TLS if your provider needs STARTTLS
      • Optional: set HELO_NAME
      • Set PULSE (delay between sends) and THREAD (workers)
      • SMTP rotation style 1 = rotate every send; style 2 = rotate after a limit

3. Load leads and message

      • Recipients tab → put emails in leads.txt (email|name|company or JSON)
      • Message tab → write HTML/plain text in message.txt
      • Add placeholders for personalization if needed
      • Set SUBJECT in Settings

4. Test before full send

      • Use Test SMTP from Settings when available
      • Add a TEST_EMAIL_ADDRESS and interval so test messages inject during the run
      • Start with a tiny lead list first

5. Start the campaign

      • Go to Send Campaign
      • Choose mode 1 — SMTP
      • Choose attachments if needed
      • Click Start and watch the dashboard / activity log
      • Use Pause/Stop if something looks wrong

6. Common SMTP issues

      • Wrong port or TLS setting
      • Provider blocks login from new IPs
      • Bad password or app-password required
      • Empty smtp.txt or bad line format
