Whether you want to send personal emails to your friends and family or want to send bulk emails to promote your product, you may require an SMTP server. While everyone cannot afford to maintain their SMTP server, it’s better to look for free smtp servers to carry out the marketing campaigns and email promotional activities. There are various free smtp servers available, and the list provided below would mainly help small and medium enterprises to enhance their marketing campaigns for no additional costs whatsoever.

In this article, we look at some of the best free open mail relay servers available online and how they can benefit personally as well as your enterprise.

Google SMTP Server

When it comes to free smtp servers, nothing can beat the services offered by Google. The SMTP server provided by Google is one of the most widely used smtp services online.

Many small and medium organizations rely heavily on Google SMTP servers to enhance their email marketing campaigns. It is better to go with a free SMTP server and that when it’s from a top brand like Google, there is no question of the quality of services offered.

The SMTP server is compatible with all other programs, applications, and scripts to send emails. Since Google is a widely used SMTP server, it is evident that emails sent from Gmail will not result as spam in the inbox.

Unless there are any specific reasons or any malicious links found or in the worst-case scenario, if the sender is blacklisted, the emails will reach safely to the user’s inbox.

But one of the main disadvantages of the Google SMTP server is that there is a limit on the number of emails that a user can send daily. Organizations that opt for the Google SMTP server would get the service completely free for the first 14 days and can send out a maximum of 500 emails per day. But when the trial period gets over, individuals or enterprises need to switch to the paid service.
