Send Time Optimization test - Email Marketing

What is Send Time Optimization?

Send Time Optimization (STO) is a strategy in email marketing that focuses on determining the best time to send emails to subscribers. This involves analyzing data and user behavior to increase the chances of your email being opened and engaged with. The goal is to enhance open rates, click-through rates (CTR), and overall engagement.

Why is Send Time Optimization Important?

Timing plays a crucial role in the success of an email campaign. Sending emails at the optimal time can significantly increase the likelihood of your message being seen, read, and acted upon. This can lead to higher conversion rates and overall better performance of your email marketing efforts. Additionally, understanding the best send times can help you build better relationships with your audience by reaching them at times when they are most receptive.
