Per-campaign daily limits
Cap how many emails each campaign sends per day so volume ramps the way deliverability wants, not all at once.
Per-account sending windows
Each mailbox sends only inside its window, 8am to 5pm ET by default, so messages land during business hours.
Weekend toggle
Pause sending on weekends with one switch, or keep it on for audiences that read inboxes seven days a week.
One-click unsubscribe
Every email carries a one-click unsubscribe (RFC 8058) or a text-STOP option. Opting out always works, instantly.
CAN-SPAM address
A compliant physical mailing address ships on every send, automatically, so no campaign ever goes out without one.
Global blocklist
Every message is checked against a global blocklist before it leaves, so suppressed and opted-out contacts are never emailed again.
