Scheduling Emails
Generally we want to schedule emails during normal working hours. We can however schedule emails at "odd" times to get a lead's attention.
Odd Times
If we're cold emailing a specific lead, other's will be doing the same.
By emailing at a little outside of normal work hours, we have a chance of standing out and catching a lead's attention.
Instead of scheduling emails to be sent between 9am - 5pm (normal working hours in North America), we can schedule emails from 7am - 8pm.
Lead's usually have their work email on their phone. By sending emails at these "odd times", we can catch them when other's aren't emailing them.
If sent early, they'll see our email before other ones.
If sent later, they'll see our email as one of the last of the day.
Experiment
Every lead will have a different schedule.
Experiementing with different schedules will help you figure out the best time to reach your leads.
