Deliver the messages your customers need after a login, payment, order, account change or system event. Alert21 connects verified business sending identities with templates, dashboard sending, API automation, logs and billing in one platform.
Transactional email is generated by a user action or a system event and delivers information needed to complete, confirm or secure a service. Common examples include login codes, payment receipts, order confirmations, password resets, account notices and operational alerts.
