SMTP For Atomic Email Marketing Software

What is SMTP?

SMTP is short for Simple Mail Transfer Protocol and it is used to transfer e-mail messages between computers.

An SMTP server performs two functions:

• Verifies proper configuration and grants permission to a computer attempting to send a message.
• Sends an outgoing message to a predefined destination and tracks the successful delivery of the message. If it is not deliverable, a message is sent back to the sender.

Where do I get an SMTP server to send mass email?

You have several options depending on the number of emails you are going to send daily.

• SMTP.com service
• Your Internet service provider (ISP)
• Free email services with SMTP support (Gmail and others)
• SMTP server that comes with hosting
• Third-party SMTP services
• Virtual private server (VPS)

SMTP from Your Internet Service Provider

Internet Service Providers usually prevent customers from sending out too many emails in a too short period of time. They achieve this by:

• using email send limits: per day, per hour or per number of recipients
• blocking the default SMTP mail server port (25)
• using whitelists, so only customers who bought an upgrade package can send out mass emails

Visit your ISP’s website and look for pages like Acceptable Use Policies, Terms of Service, etc. to find out more.

Web-based email services with SMTP support

Many web-based email services support SMTP protocol, so you can use products like Atomic Mail Sender to send mass email. Just like ISPs, they have outgoing mail restrictions (for example, Gmail lets you send not more than 500 emails a day). Luckily, Atomic Mail Sender and Atomic Email Studio support the use of multiple SMTP accounts, and they can be used sequentially: first email goes through server1, second goes through server2, etc.

SMTP and Your Hosting

If you have a website you probably can send email through the SMTP server that comes with your website. Of course you might want to use a different hosting company, not the one that hosts your website.

Third-party SMTP services

Third-party SMTP providers is the way to go if you want your emails delivered without much effort and technical knowledge from your side. You determine the number of emails you want to send monthly and buy a package that includes that number of emails.

Virtual private server (VPS)

A virtual private server (VPS) or virtual dedicated server (VDS) is a great solution for emailing without limitations. A word of warning first, this method is not for newbies - you should be able to manage a Windows server (or hire somebody who can). Your server will have a unique IP address and the hosting company does not really care what you do with your server, especially if you go offshore. We have positive feedback from our clients about this Malaysian VPS hosting.
