Four Ways to Determine the Optimal Send Time of Your Email Marketing Campaign

Assuming you have an opt-in form on your Web site, allow the subscribers to select the time period they'd like to receive emails when they subscribe.

Consider segmenting based on time zone. If your subscribers provided their mailing addresses when opting in, segment your list according to their state/zip code and corresponding time zones. When you've determined optimum mailing times this ensures that your message reaches subscribers across the country all at the same local time period.

Survey your subscribers via email as to what time of the day they would most like to receive emails – and give them a half dozen time periods to choose from. Then send emails to the responding subscribers based on their preferences.

Conduct a mini focus group by contacting a dozen of your subscribers and finding out what time they'd like to receive emails. Use these conversations to also learn what types of information and format would be most valuable and preferred.
