Frequently Asked Questions

What is SMTP server and, Email Server?

In the simple word, Simple Mail Transfer Protocol(SMTP server) is an Internet standard for email transmission. First defined by RFC 821 in 1982, it was updated in 2008 with Extended SMTP additions by RFC 5321; which is the protocol in widespread use today.

In short, an SMTP server is an application that handles and delivers email. Whenever you send an email message, your email client interacts with an SMTP server, which, in turn, connects to a remote SMTP server to complete the delivery.

When sending large volumes of mail, it is particularly important to have a powerful, high-deliverability SMTP server handle the operation. This type of server excels at fast delivery and includes critical deliverability features that have become a necessity in today’s fast-changing email environment.

What is Email Server?

A mail server (or email server) is a computer system that sends and receives email. In many cases, web servers and mail servers are combined in a single machine. However, large ISPs and public email services (such as Gmail and Hotmail) may use dedicated hardware for sending and receiving email.

In order for a computer system to function as a mail server, it must include Email server software. This software allows the system administrator to create and manage email accounts for any domains hosted on the server.

For example, if the server hosts the domain name “,” it can provide email accounts ending in “”

What is Transactional Email Service?

If you are looking for a Transactional SMTP Server or Transactional Email Service, then you probably have an application that sends out either marketing or transactional messages and is searching for a host to relay these messages in bulk. Or perhaps you are sending both transactional and marketing messages and would like to find a single provider to handle your deliveries. If you’re not sure what type of messages you are sending but just know your requirement to send bulk mail, read on. Understanding what you’re sending and searching the right plan and provider for your types of messages will improve both your relationship with an SMTP service as well as your email deliveries.

Emails that are “Transactional” in nature include customer alerts, notifications, receipts, invoices, and any other category of message that recipients would not consider to be advertising, marketing or in any way “commercial” in nature. Transactional Emails are not subject to the CAN-SPAM act, provided they are genuinely transactional messages and do not consist of falsified header information.

On the other hand, messages that are “Marketing” in nature include newsletters, promotional messages, advertisements and any message a recipient would classify as commercial. Marketing Mails are governed by the CAN-SPAM act and anyone sending marketing messages should understand and observe the points outlined by this law.

Both transactional and marketing messages are bulk in nature and should not be sent out on a regular email hosting server. In the case of transactional messages, this is not always right. If your email hosting provider does not throttle or rate limit messages, it is possible to send transactional messages in low volumes through a proper email hosting service. However, low volume is the key here, and the moment you exceed what a host considers to be low volume and are categorized as a bulk sender is when you need to look at a third party solution for your transactional sending.

Why SMTP Service is important?

So if you’ve gotten this far, you can probably identify the type(s) of messages you are sending. If you’re sending newsletters, you’re in the marketing camp. If you’re sending order receipts, you’re a transactional sender. Because SMTP hosting (Transactional Email Service) plans generally come in these two flavors, transactional and marketing, knowing what kind of messages you are planning to send makes a variety of the type of SMTP hosting plan you select. Transactional Email Service | Transactional SMTP Service

Though transactional and marketing servers are both considered “bulk” in terms of the overall quantity of messages they send, the manner in which they relay messages and their relative queue sizes differ extremely. Generally, a transactional SMTP server has low queues and relays messages quickly. This is because of transactional senders relay in small batches, hundreds of messages at a time or even singly. Transactional SMTP Server is optimized for senders relaying small quantities steadily over time and, with relatively low queues, can quickly deliver messages. Transactional SMTP Service | Transactional Email Service | SMTP Server

What this means for a sender is never to send Transactionally and marketing messages out through the same server. Sending Transactional messages through a marketing server will result in slow deliveries of messages that might be timely in nature. Imagine waiting 2 hours for a password reset or an order confirmation. The opposite scenario, sending marketing messages to a Transactional SMTP server, will cause a queue bottleneck for legitimate transactional senders and slow down their deliveries.
