Why Do You Need SMTP Services?

SMTP stands for Simple Mail Transfer Protocol. It is the industry standard for sending electronic messages or emails. It uses proper authentication, which increases the chances of your emails being delivered properly.

SMTP Services for Email Deliverability

If you’ve got a website, you may have set up automated user-triggered emails to notify users about their activity on your site. For example, when they register a new account, change a password, purchase a product, etc.

But a lot of times, transactional emails like these fail to reach the users’ inboxes. And, you may be losing revenue because of the breakdown in communication.

These failures happen when your mailing system is not configured correctly. For example, if you’re using WordPress, then the problem occurs because its default PHP mail() function is not configured correctly by most hosting services.

So, the solution to this problem is to use an SMTP service that configures email authentication properly for you.

With that said, let’s take a look at the best SMTP services for reliable email marketing.
