Email Send Time Optimization
If you have ever wondered, “When is the best time to send my email campaigns?” – well, here may be an answer for you.
Send time optimization is a feature offered by some Email Service Providers (ESPs). It allows you to set a duration window (e.g. send emails for Campaign A between 7am and 7pm) within which to send your campaign emails. This send window could be a few hours long or a few days long.
The technology will automatically calculate the best time to send the email for each individual subscriber (based on their previous open history) and send the email at that time.
Tests suggest that optimizing send times for individual subscribers tends to significantly improve open and click rates.
