Email engagement
Signal sends your email, records what happens to it, and keeps anyone who bounced, complained or unsubscribed off every future send.
Import by CSV with column mapping, validation and duplicate detection. Consent source is recorded on every contact.
One-off messages and campaigns from reusable templates, with a confirmation summary before anything leaves.
Deliveries, bounces, complaints, opens and clicks are stored as they arrive — not borrowed from a provider dashboard.
Hard bounces, spam complaints and unsubscribes are blocked immediately and permanently.
