Send email on your users schedule

The best time to send your customer email is when they are awake… and at their computers. When your customers are distributed throughout the world it gets a little tricky.

We read somewhere that open rates at 9am and 4pm are significantly higher than any other time of the day. So I wrote this to send all of our users an email in the morning according to their timezone.

This schedules a background sidekiq job for 9:25am in the users timezone.

# Set zone to the users time zone = user.time_zone

# convert time to UTC
user_time_to_utc ='2012-10-22 09:25:00').utc
puts "Scheduling for #{user.login} at #{user_time_to_utc}"

# Schedule the sidekiq job
