What keeps going wrong
Ecommerce-first platforms treat B2B, agencies, and service businesses as an afterthought.
AI Copy Studio
Great campaigns die silently in spam folders, and marketers find out weeks later in a chart.
Per-Person Send-Time
Writing, segmenting, and scheduling a single campaign still burns a full day.
Living Segments
What Signal does
Signal writes on-brand copy, picks each person's best send time, and guards your sender reputation, so every campaign lands, gets opened, and earns revenue.
AI Copy Studio
Generates subject lines, body copy, and variants in your brand voice, trained on your best-performing sends, with one-click humanizing edits.
Per-Person Send-Time
Delivers each email at the moment that individual subscriber historically opens, not one blast time for everyone.
Living Segments
Segments that rebuild themselves continuously from behavior: "about to churn," "ready to buy again," "opens but never clicks."
Deliverability Intelligence
Monitors inbox placement, spam-trap risk, and domain reputation, warning you before a campaign hurts your sender score.
