FAQ

Is unsubscribe required for B2B cold email?+

CAN-SPAM applies to bulk commercial email and requires a clear opt-out. One-to-one B2B sales email is in a fuzzier zone but the safe posture is to include opt-out availability and honour opt-outs within 10 business days.

Nate built Outsolvi after watching every email-tracking tool he had ever used lie to him about opens. Outsolvi grades every open as a person or a machine, in Outlook and Gmail, so the number on the dashboard is one a rep can actually act on.
