Top 5 Reasons That Can Cause Email Delivery Failure
When an error happens in the delivery of an email, it can be very depressing to realize that some recipients of your email never saw it, despite your best efforts to send emails that engage your audience or clients.
You need to educate yourself on the various things that can go wrong during the delivery process if you want to be sure that your emails always reach the people to whom they are addressed. There are essentially three reasons that can cause email delivery failure to their recipients:
1. Bounces
The simplest scenario is when you receive a bounce message, which can occur for a number of reasons. For example, if the recipient's address has too many characters (known as a soft bounce because you only need to wait before sending again), or even worse, if it does not exist at all (a hard bounce: you need to remove the account from your list). In this scenario, all that happens is that the inbound server sends you an email telling you that the message has been deleted. These emails typically take the form of the standard "Mailer-Daemon" or "Postmaster" warnings.
2. Malware attack
What should you do if you receive a notification that reads "Mail Delivery Failure" for mails that you have not sent at all? It is possible that you have been the victim of a malicious software attack, in which a virus is utilizing your email account to send spam emails. This would explain where all of the bounces you received came from.

The actual cause could be a worm infection (you should run your antivirus software right away), or it could be a practice known as "spoofing," in which a spammer impersonates you by using your email address as part of their ruse. Obtaining email authentication is something you should think about doing because avoiding problems of this nature is not an easy task.
3. SMTP issues
SMTP can be another reason for email delivery issues. Even if the recipient's inbox does exist, even if it has plenty of space, and even if you have followed all of the best practices for a newsletter campaign, a message still has a chance of being banned by an anti-spam filter and hence being unable to reach the inbox of the recipient. That can depend on the SMTP server you're using; if the reputation of the sender IP is very poor, or if it's even been put on a blacklist, the recipient might refuse to accept the message, causing it to be rejected. And the worst part about it is that you won't be aware of any of that at all.
Using a regular free SMTP server, on the other hand, can drastically lower your delivery rate because it relies on generic IPs that are not monitored. On the other hand, if you rely on a professional server such as turbo SMTP, your emails will be sent using only guaranteed IPs and with the appropriate authentication, maximizing the capacity of each message to reach the appropriate inbox.
Conclusion:
Nowadays, email communication is extremely important, and it's Infinitivehost's responsibility to guarantee that it runs smoothly. Utilizing your own server is a great answer to many of the email delivery issues mentioned above. This will provide you with a fresh, dedicated IP address, which, in comparison to the shared IP numbers that you typically acquire, is a great deal safer.
