Free SMTP Servers for Sending Emails – 2022

Problems with Sending Email

Basically, You can differentiate the emails that you need to send into two main types, i.e bulk email, and transactional email.

• The first type i.e bulk emails are the ones where you can send mass emails to multiple users (list of subscribers) all at once.
• The second type of email is the transactional emails that are sent to individual recipients and it is one to one communication- based on the recipient’s activity. Moreover, it is the recipient who triggers the email to be sent in their direction.

Transactional emails are an important type of email-based communication between a business and its audience or customer base. In a nutshell, if you have the tool, plugin, web service, etc and you want a particular thing to communicate with the user automatically based on specific triggers then it is when transactional email happens.

In that scenario, you do not have to do any work, your tools algorithm will detect the things and triggers the email to the particular user (one to one communication) when any transaction happens. Transactional emails can be like:

• New account creation emails
• Order confirmation mail
• Comment responded to mail, etc

So, transactional emails are important and must be delivered to your recipients without fail and fast.

You can achieve this by using PHP’s mail() function or similar in other technologies but these are not recommended as you can run into some deliverability issue here. Especially when you have a shared web server and the server’s IP might already be on spam blacklists, which will send your emails in the recipient’s spam folder and hence conflict with the deliverability. And therefore, this is not a recommended way to sent transactional emails.
