What is SMTP

SMTP aka Simple Mail Transfer Protocol is a standard for email transmission. It is a TCP/IP protocol that is used while sending or receiving an email. Users generally use a service that sends email through SMTP and receives email via POP3/IMAP Protocol. This is because of the limited capability of SMTP to queue messages at the receiving end.

SMTP is a standard that is used by the hosting services and email providers all over the world. Each host has its own rules when it comes to allowing custom SMTP servers. Some do not allow other SMTP servers than their own mail servers. Such practices hinder the flexibility of shifting to the SMTP providers that you want. If you are stuck with such a host, you may consider switching to a more accommodative one.

The field of SMTP server services is as diverse as any internet infrastructure. There are some premium options available. Some offer free access. But the ones that we are reviewing are at par with premium services and can be quite beneficial for startups and businesses with lower volume of emails. Once your email flow boosts, you can surely try the premium option.

All these services are backed up by a huge infrastructure and you can rely on their services. But before we go to the list of today’s best candidates for free SMTP server providers, let’s first understand the need of SMTP.

Need For SMTP

Suppose, you want to send a message to another computer but each time you are using a different format in which you are sending the message. This will cause confusion and it will be tedious to decode each message if random algorithms are used each time to send the message. Thus, we need a defined standard. Same is the case with email. An email is a message that is passed from one computer to another, or as in reality, from one server to another. To standardize this sending of emails between servers, a protocol is fixed and is to be used by all email service providers. This is called the Simple Mail Transfer Protocol or in short, SMTP. Got the idea?

Now, Let’s use a technical language. SMTP is used to send messages from an email client to an email server. POP and IMAP protocols are used to receive the messages. Now, most of the emails are Spam, to give you an idea, roughly 80%. To deal with this menace, email providers employ various strategies. One of the key strategy is to identify if the mail is sent by a reputed SMTP server. If not, your email is more than likely to end up in the Spam Folder, meaning your message will never be read by the receiver, defeating the basic purpose of sending the message in the first place.

Email deliverability is the most important factor to be ensured in any email communication. What good is your email if it only ends in the spam folder or never gets delivered? This requires that you use a reliable email delivery service. Apart from that, you can use these tips to increase email deliverability.

We have reviewed some of the top SMTP servers that offer some of their services for free. Thus, you can be sure about reliability and deliverability while using these free SMTP servers.

Let’s look at the Top free SMTP server providers now.

Best Free SMTP Servers Reviewed

There are many SMTP servers out there but we are going to review the selected few, and these are:

  1. Elastic Email
  2. Amazon SES
  3. Mailjet
  4. Mailgun
  5. Sendgrid
  6. Sendpulse
  7. Sparkpost

7. Sparkpost


Sparkpost is reliable when it comes to email deliverability but it’s free offerings are not that impressive. You get 15,000 emails for first 30 days. Then this reduces to 500 per month. Although free support during the first 30 days might seem attractive, one might conclude that there isn’t much to offer when comes to free offering of SMTP server. Still, if you are convinced with this site and don’t have much demands about email volume, you may find this a good option.

Sparkpost offers flexible pricing depending on how many emails you need to send per month. For 50,000 emails in a month it charges you $9 per month. A requirement of 1,50,000 emails per month will cost you $49 for the standard plan. You can scale up as per your requirement from 15,000 emails to 10 million emails per month.

6. Sendpulse


A better option than Sparkpost, Sendpulse offers 2500 emails per month. But that’s the only thing. There are no extra features. Even the premium plans are bit expensive. As far as value for money is to be considered, I won’t recommend this service strongly.

Premium plan starts at $7.88 in which you get unlimited emails for 2500 subscribers.

5. Sendgrid


One of the most popular SMTP email provider out there, Sendgrid has scalability. Their prices are flexible and plans are scalable. But when it comes to free offering, they provide a modest value proposition. You get 40,000 emails for first 30 days. And then each day, you get 100 emails. That’s about 3000 emails per month. If you are just starting your business, this might be more than enough for you. You get the assurance of reliability by Sendgrid.

The premium plan starts at $9.95 per month and includes 1,00,000 emails per month.

4. Mailgun

If you were to judge the Free SMTP server offerings solely based on attractiveness, then Mailgun will surely beat the competition. Don’t misjudge me. By “attractiveness” I mean a free offering with no binding conditions. With Mailgun you get 10,000 emails per month, doesn’t matter if you send or receive. There is no daily limit. A straight up quota. Got what I was talking about?

Mailgun comes up with a pretty expensive plan of  $79 per month which includes 1,00,000 emails per month and 1000 validations.

3. Mailjet

mailjet


The offering of Mailjet is exactly double of that offered by Sendgrid. More specifically, you get 6000 emails per month, with a limit of 200 per day. In this sense, you get more in terms of volume when compared to Sendgrid. The premium options are also lucrative. If you are looking to scale up your business in near future then Mailjet might be a better option for you than Sendgrid.

Mailjet premium plans start at $8.69 per month which limits the user with 30,000 emails per month. There is no daily sending limit but the monthly limit is somewhat restricting.

2. Amazon SES

So far the best option  for free SMTP servers. That’s simply because of its unmatched affordability. You get first 62,000 emails you send for free each month. This is a huge number by any means. But there is a catch. You need to send the email from an application hosted on Amazon EC2,  also known as Amazon Elastic Compute Cloud. For other email clients, it charges just $0.10 for every 1000 emails you send. With the infrastructure of Amazon, reliability is never an issue. This is a unique value-for-money proposition.

You  can buy Amazon EC2 T3 micro or nano which will cost you $4-$8. You can pay one time cost of $59 for Sendy which sends emails using SES.

1. Elastic Email

This is one of the most cost effective offerings out there. The Unlimited plan starts with $9 per month and includes unlimited emails for 2500 subscribers. This unlimited emails features is what makes it an affordable choice for those who send bulk emails per month. There is another payment option called “Pay as you go”. This option costs just $0.09 per 1000 emails. That is 11,111 emails for just a dollar. Affordable, isn’t it?
