What are SMTP services
E -mails are one of the best ways to communicate with their users. You can use them from leads to customers who use a number of e -mails.
However, the problem is that the standard WordPress mailer uses this wp_mail()
Function that is dependent on the PHP mail()
Function. This can lead to an unreliable e -mail delivery.
This is only a unusual way to say that the standard WordPress e -emails depends on your webhosting server in order to process the process.
Unfortunately, this setup is not very reliable because many servers are not properly configured for sending e -mails. As a result, your e -mails may be lost, end up in Spam folders or do not send them at all.
For this reason, we recommend using an SMTP service and a simple mail transfer protocol.
SMTP services ensure that your e -mails reach the intended recipient without losing traffic. It takes care of the complexity of the routing of e -mail via different servers and ensures that you achieve your goal efficiently.
In addition, provide error codes and messages if an e -mail cannot be delivered. A complete inbox or an incorrect e -mail address, for example, triggers a jump message that helps the sender to understand the problem.
