Transactional email service is a 3rd party automated email between a recipient and a sender. The main benefit of sending transactional emails is to instantaneously connect and communicate valuable information to customers at key moments of the customer experience. Communication is essential to a positive customer experience. If a customer submits a support request but does not get a confirmation that it was received, it can be frustrating. Whether you’re sending a contact form request, coupon, promotion, password reset, account update, or any other email communication, transactional email service can help you get those messages/emails delivered with 100% surety and on time.
