Top 3 reasons your emails could bounce

After your email marketing campaign is dispatched, it might come to your attention that your email marketing report indicates that some of the email addresses to which you have just sent your newsletter are now marked as Bounced

While email bounces occur for various reasons, they can dramatically affect your reputation. This means that if you don't take them seriously, an increasing number of bounced email addresses in your recipient list may eventually damage your deliverability. Being proactive about bounces is always a wise course of action if you want to make sure that your campaigns reach all the inboxes they should.

Let's examine the top 3 reasons why an email may be considered as Bounced: 

A. Invalid recipient

An invalid recipient address is the most common reason why it might bounce your campaign back.
If the recipient's address is a professional one, then it is very likely that they have left the organization. Therefore, they can no longer receive emails in the specific email address that they used to sign up for your newsletter. If your recipient has stopped working for the company indicated in the suffix of their email address (re: the moosend part of, it is only natural that their email address is no longer valid.
B. Non-existent address

An email address may also bounce if it is non-existent, meaning that it never existed in the first place, so it cannot be reached. This is usually due to a misspelling when typing the address during the sign-up process for your newsletter campaigns.

It is also probable that if the email address doesn't seem to have any obvious misspellings, the recipient might have provided you with a false email address. This is not uncommon if you ask people to give you their email address in exchange for providing them with an online offer.
C. Full mailbox

Another reason why an email address may bounce your campaign back is that the mailbox behind the address is full. It makes perfect sense that a full mailbox doesn't have any available space to receive more emails or your newsletter campaign. No reason to worry though, your campaign will be resent until it gets delivered (indicating that the mailbox now has some space available to accept more emails). Alternatively, after a few unsuccessful attempts have been made, the address will reach a hard bounce status meaning it is considered unreachable.
