While the optimal send time can vary widely depending on your specific audience, some generally recognized guidelines include:
Tuesdays and Thursdays: These days are often cited as having the highest engagement rates. Mid-Morning (10 AM - 11 AM): Many people check their emails during this time, making it a popular choice. Early Afternoon (1 PM - 2 PM): Post-lunch hours can also be effective as people return to their desks and check emails.
