Smart Send is an AI-powered scheduling mode that delivers your email to each contact at the time they're most likely to open it. Instead of blasting everyone at 9am, Smart Send analyzes each contact's historical engagement patterns and delivers at their individual optimal time.
How Smart Send works
SendX analyzes each contact's past open and click behavior
It identifies the time window when each contact is most engaged
Your email is queued and delivered to each contact at their predicted best time
Contacts without enough engagement history receive the email at your specified fallback time

FAQ
How much data does Smart Send need?
Smart Send works best when contacts have at least a few weeks of engagement history. For newer contacts, it uses the fallback time you specify.
Does Smart Send spread delivery over multiple days?
Smart Send delivers within a 24-hour window around your selected date. It won't delay emails by days.
