If your business is conducting any form of email marketing campaigns, you no doubt have had emails that have bounced back. If you have wondered why this is happening, read on. In this post, we will take a look at 5 of the most common reasons why emails you send might be bouncing back.
1) You’re sending emails to non-existent email addresses
A very common reason for bounces is that the email address you are sending emails to simply doesn’t exist. In these cases, your email marketing platform will mark it as a “non-existent email address.”
This can happen for a number of reasons, the most common one being that a typo was made when the email address was entered. However, in a worst case scenario, you might find that the email address doesn’t exist at all, i.e. it was made up. People often leave fake email addresses when they are signing up for something temporarily or just for the sake of whatever freebie you’re offering.
To avoid such cases, it is highly advised that you verify email lists as often as you can and keep them clean as you can.
2) The email is currently undeliverable
Sometimes, emails will not be delivered because the receiving server is currently unavailable or temporarily overloaded. If the recipient’s email server is under maintenance or if it has currently crashed, you would experience a bounce back that would be categorized as “undeliverable email”. This is an issue that most often resolves itself after a certain period of time, so it’s not something you need to worry too much about.
3) Your recipients’ mailboxes are full
If the person who you are trying to send emails to has reached their inbox quota, it’s possible that your email will not reach them. Whether the quota is a certain number of emails or a certain size, if it has been exceeded, you will find that your emails will not be delivered.
In such cases, you can simply try again after a little while because it is likely that your recipient has cleared their inbox. If the bounces keep continuing, however, it’s wise to give up on those particular email addresses.
4) Your recipient is on vacation/has auto-reply turned on
If your email successfully reaches the intended recipient, but they are on vacation or can’t otherwise check their emails, you will receive this particular bounce back message. It’s nothing to worry about, because people on vacation do return from their vacations and then they’ll resume checking their emails and whatnot.
However, keeping an eye on these email addresses is advised, just in case they are abandoned permanently with the auto-reply turned on.
5) Emails have been blocked on the receiver’s end
There can also be cases where emails have been blocked by the receiving server. In these cases, you will be alerted that the email couldn’t be delivered because it was blocked. This issue most often happens when the email address you are sending to belongs to government entities, private corporations, schools, universities or other similar institutions.
You can only overcome this by trying to directly get in touch with the institution blocking your email and asking them to unblock you. If it doesn’t happen, you’re better off not sending further emails to those addresses.
This kind of bounce backs can also happen if an email address has you blacklisted. In those cases, it’s not even worth contacting them in other ways. Just take them off your list and move on.
