Every business holder is well aware of the power that proper marketing has over a growing customer base, which is pre-programmed to bring in profit. These days, email marketing belongs to the best means that marketing teams operate with. The only downside of the approach is the fact that you can barely predict the email deliverability rates without an informative email deliverability test.

Once you spot the issue, you, as a responsible business owner, would crave the means to improve the situation and eliminate the problem. That is where effective email deliverability platforms come in handy. Yet, while building your platform may not be an affordable and quite convenient idea, services like the Mailgun SMTP system offer a helping hand.

What Is Mailgun? A brief overview

Before you learn how to send email with SMTP through Mailgun, you need to be fully aware of what the service stands for and whether it is the best email delivery platform you are looking for. The system is designed to provide seamless Mailgun SMTP relay along with the API services to help various business owners, companies, developers, and enterprises succeed with email service integration. The integration will ensure that you can easily send, receive, and monitor every email. The utter control is aimed at absolute reputation spike, marketing success, and revenue growth.

SMTP – general SMTP server introduction

SMTP abbreviation stands for Simple Mail Transfer Protocol. In case you are poorly familiar with the field, such a complex notion would mean little to you. Yet, an SMTP server is a type of protocol that is responsible for everything that concerns tracking emails. So if you want to be constantly updated on how your marketing emails are handled, starting with the outgoing operation and ending with what the receiver does with it, you should consider implementing it into the workflow.

Technically speaking, the SMTP server is a part of the TCP/IP protocol, the application layer component. The protocol is designed to transfer every sent email across the existing networks. The notion is closely intertwined with the MTA (Mail Transfer Agent). This ensures that every message you write and send over email gets to the correct inbox.

What is Mailgun SMTP?

Generally, most email service providers, such as Gmail, come set with their encoded servers. Yet, most of those servers are provided with email limits. For instance, some providers decide that sending more than 1000 emails an hour is considered a spamming activity. Once the server detects such activity, your account may be blocked, temporarily or permanently.

To avoid those limits and potential blockage, you can change the default server and use SMTP Mailgun instead. Once you set the SMTP server up, you will be able to route your outgoing email campaigns and ensure that they get right into the inbox, not in the Spam folder, no matter the number of messages sent out.

In order to operate properly, the chosen SMTP service should be authenticated. It takes such data provided as a username, password, server address, Mailgun SMTP port, and protocol to succeed with the task. In the case of the Mailgun service, you will be offered all the mentioned details right after you provide the domain that you want to send messages from.

Why do you need an SMTP service?

As you already know, most email service providers offer default SMTP service options. Thus, you may not be confident whether you should seek an alternative.

The fact is that most SMTP default options are encoded to deal with small to average email delivery volumes. If you run a small business, the default SMTP service may be even sufficient. However, as your clientele grows, the default servers will start to lag. There are cases when Gmail accounts are blocked due to exceeding the outgoing email rates.

In times like this, SMTP Mailgun comes to the rescue. The service is designed to deal with the task effectively. Besides, it takes literary minutes to browse through and succeed with SMTP settings, so the process is simple and intuitive.

Do you need to buy an SMTP service?

The number of free SMTP service options is overwhelming. Thus, many people wonder if they should invest into pricey offers or just go with the flow. Here’s a list of proofs that ‘free’ doesn’t work in the majority of cases.

Time

It takes time and effort to work on the marketing email campaign. Can you imagine what a waste of time it would be if your emails turned out to be blocked? Things like this will never happen to you if you stick with a professional SMTP send mail service. Mailgun, for instance, offers a great variety of plans to pick from, even a free trial, so that everyone can find the most suitable option.

Email deliverability

The primary goal of implementing an SMTP server into the process is to ensure that each and every email campaign not only reaches the recipient, but also catches attention. An email that ends up in the Spam folder is unlikely to trigger any interest. Services like Mailgun ensure that the message ends up in the primary inbox, while some low-cost or free systems cannot guarantee it.

Reputation

While most people assume that an SMTP service is nothing more than a technical solution to add to the workflow, you should realize that it adds to your business reputation. The fact that your emails go straight to the main inbox means that you are a reputable vendor, which will improve the client’s base growth.

Which features should an expert SMTP send mail service have?

Many people look at the price range once they decide to find a reliable SMTP server to work with in the first place. However, there are more vital points to evaluate, and they are as follows:

  • Validation service – there’s little use to invest in a third-party SMTP service if it can’t prove that the email addresses are active.
  • Enhanced analytics – it helps to be aware of the sent emails reaching the inbox and of the following actions that the recipient takes (open rates, for instance).
  • Informative logs – you should be alarmed about the potential issues and delivery failures so that you can fix those ASAP.
  • Deliverability features – it helps to work on bounce rate decrease and spam complaints.

Benefits of SMTP Mailgun service

Mailgun SMTP server is unique and peculiar in a variety of ways. The better you understand the perks of the branded SMTP relay, the easier it will be to realize why to choose the SMTP Mailgun service to boost the deliverability experience of your email campaign.

SMTP relay increases deliverability

Mailgun SMTP relay is your perfect opportunity to improve the deliverability rates. You can use any of the SPF, DKIM, and DMARC records to your advantage and authenticate your domain name. Once you introduce the Mailgun email validation API to the web forms in use, you’ll be amazed at the speed that the bounce rate is decreasing at, along with the reduced spam complaints. There’s also one-on-one support provided to monitor all the deliverability rates and boost them further.

SMTP service can process incoming emails

The system allows you to get inbound emails converted to JSON from MIME. The email service is designed to enable email content posting right to the native application. Besides, you can have your reply handling automated, spam routed to its filter, and the list of useful functions doesn’t end here.

SMTP server tracks email events

There is a user-friendly control panel that the Mailgun system will grant you access to. So should you decide to have a closer look at the marketing emails’ metrics and logs sent via Mailgun SMTP; you can access those in a matter of seconds. Besides, the SMTP server enables a user to monitor such events as delivery failures, clicks, and unsubscribed rates. On top of that, branded analytics will ensure that you are fully aware of how effective each launched campaign is so that you can update and improve it when needed.

When should you send email with SMTP?

There are two ways that Mailgun deals with marketing and transactional emails – SMTP server and API. If you can’t decide which options suit your case better, you should remember a few things in order to send email with SMTP at the right time. You should use the SMTP service if you can’t implement the API into your app. This may happen since the developed applications don’t support API. At times, the system in use is compliant only with SMTP relay, so the choice is obvious.

Generally, both API and SMTP service are designed to deal with the same task. Yet, they deal with it differently. One of the main downsides of SMTP is that it is a bit slower than API.

What is a Mailgun SMTP port?

Now, when you know that all the primary services that Mailgun SMTP relay offers are intertwined with emails, their transition, delivery, and potential improvement, you may have some questions as to how they end up in the recipients’ inboxes. That is where a Mailgun SMTP port comes into play.

Mailgun SMTP covers the process when the emails travel across the Internet. A computer port is a way of how a computer is connected to the network. So, it’s safe to say that a Mailgun SMTP port is a combination of both. This means that the port will send an email via a network and will send it to the recipient at the same time.

40 years ago, there was a single port in use, and that was both a blessing and a curse. These days, there are different ports. The better you understand which Mailgun port suits you best, the easier the workflow and adjustment will be.

Main types of SMTP service ports

There are four primary ports that you should be ready to choose from when it comes to SMTP relay:

  • Port 25
  • Port 465
  • Port 2525
  • Port 587

Folderly experts will help you understand what each of those ports aims at and when you need to pick a certain option.

Port 25

This is what everything has started from. Port 25 was introduced over 40 years ago, and it still functions. SMTP relay is the main area where the port is used. If you need reminding: SMTP relaying is the process of email transmission from server to server.

Should you decide to send an email with SMTP through port 25, you should think twice. The thing is that most residential ISPs, along with cloud-hosting providers, block the port. The primary reason behind the blockage is to tame the spam that may be relayed from compromised sources. It is advised to use the option only if you are managing a server specifically.

Port 465

You can no longer use the port to deal with SMTP server related operations. So, you should add it to your blacklist and avoid mistakenly using it.

Port 2525

Mailgun has an alternative port to offer if others are blocked. 2525 is a mirror of the 587 option, yet it is a non-traditional type. Due to that difference, the port is allowed on the client’s ISPs and Cloud Hosting providers, such as Google Computer Engine. Port 2525 is known to support TLS encryption. Thus, you can use it any time when you experience some issues with other ports.

Port 587

Mailgun usually presents Port 587 as a default option that all clients should exploit. This is because it supports TLS encryption and is known to provide the best results in the field. However, if you know that you are blocked by the hosting provider or upstream network, it may be wise to explore other port variations.

Conclusion

If you think that the SMTP server is the sole component of successful email delivery, it may be worth mentioning that while it is among the most critical elements, it is not the only one. For example, you can run a DKIM record check to increase the chances of success, or you can simply implement Folderly for Mailgun and let the people experienced with the field do all the work for you.
