Transactional Email Service

SocketLabs transactional email service helps senders deliver important alerts and notifications to customers on time, every time.

What is Transactional Email?

Transactional email (sometimes referred to as ‘triggered’ or ‘automated email’) is a form of email communication in which real time messages are sent to users after a specific action has been performed within an application or website.

How is Transactional Email Different Than Marketing Email?

Marketing email is more promotional in nature. Examples of marketing emails are newsletters, offers, discounts, and other content that is sent to one or more recipients with the goal to drive a sale.

Transactional emails are more informational. With transactional emails, you’ll find that the content relates directly to an action taken by the user or customer. Examples of transactional emails are password resets, receipts, and shipping notifications.

How Transactional Email Works

With SocketLabs, you can send transactional email either through SMTP or our Email API.

SMTP Transactional Email Service

Many senders choose to use an SMTP relay service to send transactional email. Sending over SMTP is as easy as plugging your SMTP credentials into an existing application.

It makes the most sense to use an SMTP relay when connecting with an existing application like a CRM or a mail client such as Outlook.

Transactional Email API
