Whenever you send an email to any of your work employees or friends, you interact with the recipient at the same time. But when it comes to transactional mails or bulk SMTP emails sent through an email marketing software such as SendinBlue, the emails are sent one after the other. The mails sent through the app can’t be sent at the same time. The emails by the app are put on a SMTP queue which means that you get temporary storage in a cloud before the processing of the mails. And when the recipient becomes ready to receive the mails, the mails get sent. Here in this article we will find out the need of having an email queueing in your phone application and how it is done.
What is Email Queue?
Email Queue is nothing but an integral component of the SMTP server of the digital world. Email queue is a system which builds an arrangement of the sent emails that are waiting to be prepared for sending to the receiver. This system is a form of Message Queuing is nothing but an asynchronous service to service communication feature. The basic work of this feature is to decouple the sender from the recipient with which the sender and recipient can communicate without being connected to each other. The queued mails just hold back for processing till the time the receiver gets available to receive them.
How Email Queues Work for Bulk Mail Server
Let’s take an example of your company to learn how an Email Queue works for bulk email smtp server hosting. Let’s assume that you are about to launch an email campaign with more than 100 recipients in your list in which your email client will interact with SMTP server to send those messages. So it means that your server will now interact with the SMTP server hosting the receiver host to provide the message.
Since we know that you are about to send more than 100 messages it is obvious that your emails will be holded in a queue by SMTP server on your host. Most of the email servers apply MTA (Mail Transfer Agent) generally known as send email for the real sending. In case the recipient’s SMTP server didn’t respond then sendmail is the one that works for sending the mails. In this case, the Email Queue will automatically turn into a sendmail queue. Generally for this type of issue, your company’s email client will get notified about issues related to SMTP.
Email Queue in your App
Generally the SMTP server consists of a management system of built-in queue. But this option is given to you only if your email campaign includes recipients of more than 100 in number. But there is no harm in saying that it’s better to have an email queue in your app for better efficiency. Here we will share with you some cases in which you will find email queue beneficial:
- If a user tries to make async actions, for eg. sending messages or notifications to more than 1000 contacts then it can be a time taking task or we can say it will be very slow if you don’t use a queue or background task.
- If your app is tracked, for eg they are looking for the amount of megabytes you use per month and you want to send the notification about the usage of 70%/80%/90% limit reach then it is only possible by email queue for sending one email to one user rather than sending more than one mail per event.
- It is also beneficial for companies or businessmen who send more than 10K transactional mails to others on a daily basis.
The bulk email smtp server hosting queue might not be able to send this much amount of tasks and because of this reason it is advised to opt for a refined email sending architecture. Refined email sending architecture is based on an asynchronous system for sending mails which will make a queue of messages very soon before they reach the mail server of the recipient. And that is how email queues work in your app and help in sending the bulk mail faster and effectively.
Test your Mail Queuing System with a Fake SMTP Server Hosting
After you set up the really advanced and helpful email sending architecture it is advised to check it before using the bulk mail server hosting. There are many fake bulk email server hosting like Mailtrap which is known to be a perfect tool for this. Mailtrap is not a tool for testing the SMTP email queuing. But, if you implement your email queue before the mail server then you can use Mailtrap later.
Maltrap provides all the necessary information and credentials like authentication method, port and other things which can help you in identifying the genuinity of the bulk email smtp server hosting. You can also get beneficial things from ready-to-use integrations for commonly used tech stacks.
The other benefit of using a fake Bulk mail SMTP server hosting is Failsafe. Failsafe is a feature that will transfer all your marketing and transactional emails to a fake POP3 server. And prevents any spam to reach the real users. And you also save yourself from improper configuration as well as authentication. And eventually, when the app starts functioning well, you will get to see the emails in your dropbox.
The most important thing to learn from this article is that the email queue has both sides of the coin. One side is positive: the bulk mail SMTP server and Email Queueing uncouples the task of receiving and sending of the emails. This factor is beneficial for bulk and mass mailing tasks. The other side of the coin is negative which is that the queued messages or emails face some failures which results in delaying the process of sending. So now it’s on you to decide how you will deal with the negative side and take advantage of the positive ones of email queuing or bulk email smtp server hosting.
