Let the data pick the subject line
Send two or more variants to a slice of your list, and SmartMailing auto-sends the winning version to everyone else based on real opens or clicks. You stop guessing which subject line works and let a small test decide.
Right message, right moment
Predictive send time learns when each individual subscriber tends to engage and schedules their copy for that window — so the same campaign reaches early-morning readers and late-night browsers each at their own best hour.
- A/B test subject lines or whole templates.
- Automatic winner selection and send.
- Per-recipient predictive send time.
- Welcome series and drip flows that run on autopilot.
Testing should be the default, not a chore you set up by hand.
Automations that keep working
Welcome series and drip flows run on their own once built — new subscribers move through the sequence automatically, so the right emails go out without you touching them.
