This will allow you to follow up more accurately and quickly than if you sent a thank you email manually. By implementing this automation, customers can confirm their payment, which may give them peace of mind when using the service.

Benefit 2: Reduce the time and effort required for manual work

Manually sending thank you emails places a burden on the person in charge and takes up a lot of time. For example, by automatically sending thank you emails, you can significantly reduce the time it takes to create emails, which you previously had to do manually. This may allow even a small number of staff to focus on customer service. Reducing the burden of manual work in this way creates an environment where staff can focus on their core tasks.

Benefit 3: Strengthens trust

To deepen trust with your customers, it is essential to communicate at the right time. For example, when a payment is completed with Square, you can deepen trust with your customers by sending a message from Gmail saying "Thank you for your purchase." Furthermore, including customer service contact information in the Gmail message may provide customers with a sense of security.
