SMTP servers



Getting an SMTP server for sending mass email

One of the most frequent questions our customers ask is where to get an SMTP server for sending emails via Atomic Mail Sender. There are quite a few options.

  • Your ISP (Internet Service Provider)
  • Free email services (Gmail and others)
  • Your hosting
  • Commercial SMTP services
  • Self-hosted or rented server (dedicated or VPS)

SMTP from Your ISP

ISPs do not want you to send commercial emails through their SMTP servers so the number of emails you can send is very low. However this can be ok for smaller lists. However first go to your ISPs website and look for pages like Acceptable Use Policies, Terms of Service, etc. to find out how many emails you can send.

Free email services with SMTP support

Many web-based email services support SMTP protocol, so you can use Atomic Mail Sender to send newsletters. Just like ISPs, they have outgoing mail restrictions (usually a few hundred emails a day). You can use several SMTP accounts because Atomic Mail Sender supports rotation of SMTP accounts.

SMTP that comes with hosting

Most of marketers and business owners have a website and email addresses like info@mycompany.com. You can send emails to people who sign up to your newsletters using this your business email.

Commercial SMTP services

Some companies specialize in providing SMTP servers and they offer monthly plans that depend on the number of emails you need to send.

One such company is SendPulse; it provides quality SMTP server for transactional email messages.

Use the SendPulse SMTP and send email messages to subscribers right from your own web-project. Take the advantage of the fast and easy integration, dedicated IP-addresses, personal tracking domain and much more SMTP service features.


Virtual private server (VPS)

A virtual private server or a dedicated server is a great option when you have know how to configure a server properly. This includes PTR records, SPF records, DKIM/DomainKeys so this is not something most people can do without hiring an expert. However in the long term this is a cheap and effective solution because your inboxing rates depend only on your mailing practices and not affected by people who try to send spam through shared smtp providers.

Whatever SMTP solution you choose Atomic Mail Sender and Atomic Email Studio will work with any of them efficiently.
