What is a bounced email?

Bounced email is an email returned to the sender as it cannot be delivered for some reason. There are two kinds of bounced email: 


1. Hard-bounced email 

Hard bounce e-mail is permanently bounced back to the sender because the address is invalid.


2. Soft-bounced email 

Soft bounce e-mail is recognized by the recipient's mail server but is returned to the sender because the recipient's mailbox is full, the mail server is temporarily unavailable, or the recipient no longer has an e-mail account at that address.


How does Mailmodo handle bounced email?

1. Hard-bounced email

Previously hard-bounced email recipients are automatically removed from your recipient list while sending a campaign


2. Soft-bounced email

Soft-bounced email recipients are temporarily removed from your recipient list for 48 hours and if an email repeatedly soft bounces 7 times, then the recipients are removed from your recipient list permanently. 


Recipient list = Total contacts - (Previously hard bounced contacts + Soft bounced contacts in the last 48 hours + Contacts repeatedly soft bounced 7 times) 


Please note that the unsubscribed contacts will also be removed from the final recipient list
