Are you looking for the best SMTP services for email marketing?
An SMTP service helps you to send emails to your users and customers from your website safely, without fail.
Emails are an important means of communication between your website and users. So, it’s essential to ensure that your emails are properly sent and delivered to your users’ inboxes. And, SMTP services help you achieve that goal.
In this article, we’ll compare the best SMTP services for email marketing.
What is SMTP? Why You Need an SMTP Service?
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.
If you’ve got a website, then 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, order a product, purchase a product, etc.
But a lot of times, your transactional emails like these may be failing to reach the users’ inbox. And, you may be losing lots of money because of the failure to communicate.
The main reason behind this problem is that 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. For WordPress sites, you can use the most popular WordPress SMTP plugin WP Mail SMTP and fix email deliverability.
