Use a Gmail App Password — not your regular password. Enable 2FA → Security → App passwords.

If an account's last N sends (across every campaign) get zero opens, it's automatically retired from sending for a while — protects your other accounts' reputation from one that's clearly landing in spam.

Sends will tunnel through this proxy in batches (see Rotation Settings) instead of going direct.

One proxy per line, in ANY of these formats — mix and match freely:
host:port · host:port:username:password · username:password@host:port · socks5://host:port · http://username:password@host:port
A protocol prefix on a line (like http://) always overrides the default below.

Pick a date/time in your local timezone.
