Timing can significantly impact the success of your email campaigns. Generally, the best times to send emails are mid-morning (around 10 AM) and mid-afternoon (around 2 PM). However, these times can vary based on your audience's habits and time zones. Conducting A/B tests can help you identify the optimal sending times for your specific audience. Additionally, analyzing past campaign data can provide insights into when your subscribers are most likely to engage with your emails.
