Sender

Sender name

Sender email address

Reply-To (optional)

Unsubscribe URL or email (optional)

For inbox placement: use a real domain address, and set SPF / DKIM / DMARC on that domain to authorize your SMTP. HTML mail is sent as multipart/alternative (plain + HTML).

Encode headers (From / Subject as RFC 2047 UTF-8 Base64)

Timing & reconnect

Delay (seconds)

Wait between each email.

Reconnect SMTP after

Off 10 20 30

Fresh SMTP session every N messages. On localhost, this is the batch size (default 10).

Message

Subject

Supports {name} {email} {phone} {emailbase64} {random9} (same as body).

Body type

Plain text HTML

Message body

Placeholders (subject & body): {name} {email} {phone} {emailbase64} {random9} — also &name& &email& &phone& &emailbase64& &random9&

Email list

One per line: Name, email@domain.com, phone

Phone is optional. Old format Name, email still works. Use {phone} in subject/body.

SMTP accounts (up to 50)

One per line: host,user,pass

Port, encryption, and auth are detected automatically (tries 587/TLS, then 465/SSL, then 25). Optional overrides: host:587,user,pass or host,user,pass,465,ssl. Leave empty for localhost — reuses one SMTP session per batch, auto-finds port (25/1025/2525), no auth.
