A hard bounce indicates that the email was actually sent to the recipient, but was unable to be delivered for some specific reason .
Why does a hard bounce occur?
The reasons why hard bounce occurs are:
Wrong email address
The server blocked delivery
Spelling mistakes in the email
Outdated domain name
Abandoned mail
1. Wrong email address
One of the reasons why hard bounces are seen is because active telegram number data the campaigns were sent to incorrect emails , that is, false ones on purpose.
It is a practice based on registering, but giving non-existent emails.
2. The server blocked the delivery
The recipient's server blocks delivery when it has identified that the sent email contains a spam section (in the subject or content) .
3. Spelling mistakes in the email
Other reasons are because the user has accidentally made one or more spelling mistakes somewhere in their email that prevent your emails from reaching them and therefore they do not receive them.
This error on the part of the user may be accidental.
4. Incorrect domain name
Continuing with the errors, in the structure of the email, the user placed an incorrect domain or one that no longer exists currently in the domain section .
By domain I mean the text after the “@”, for example, gmail.com or outlook.com.
5. Abandoned mail
In this case, a hard bounce occurs not because the user typed an error or left a false email address, but because they used it but no longer do so.
An abandoned email is a clear example of a permanent reason to stop sending emails.
Consequences of hard rebounds
One of the consequences of a hard bounce is that your email marketing strategy will be affected by not offering the results planned from the beginning .
Another consequence is that the recipients will not receive any of your informative emails or offers , so it will not contribute to the ROI (return on investment) or to the specific objective (such as, for example, getting them to enter your website).

How to reduce hard bounce?
To reduce hard bounces, there are several processes you can implement, such as double opt-in and performing frequent cleanups manually or automatically .
1. Double opt-in
This technique does not eliminate the current hard bounce, but it prevents it, that is, double opt-in is a double validation process to confirm a subscription .
By adding the extra step of “Confirmation” you will have at your disposal a subscriber base that is truly interested in receiving your content and above all, that has not entered a false or misspelled email.
2. Frequent cleaning
A process that will most effectively reduce hard bounce is frequent cleaning.
This technique is based on manually or automatically deleting those subscribers who are causing the hard bounce and therefore the deficiency of your email marketing strategies.
To delete them, you must start with the subscribers who have not opened your emails and then continue with the inactive ones. With this process, you cause your list to be cleaned and in good condition.
If you correctly apply double opt-in and frequent cleaning, you will get a quality list.
Difference between hard bounce and soft bounce
To better understand the difference between hard rebound and soft rebound , first understand the concept of the latter.
A soft bounce occurs when the email is recognized by the server , but is still returned to the sender because a temporary failure occurred.
Temporary failure may occur because:
There are errors with the DNS
The recipient's inbox is full
The email message is very large
So, now that you know the concept and why it occurs, you know the main difference... The difference between hard bounce and soft bounce is that the first is a permanent failure and the second is a temporary one .
In other words, hard bounce has no solution with emails and soft bounce does tend to have a solution to recover subscribers (reactivate them with the brand)
Although it is worth mentioning that if soft bounces of the same email accumulate, it will be deleted, as in the case of hard bounces.
