What is a bounced email and how does Mailmodo handles it?
Last updated December 24, 2023
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| Day 0 | |
| Total contacts | 100 |
| Total soft-bounced contacts | 0 |
| Total hard-bounced contacts | 0 |
| Assuming the total contacts remain constant further | |
| Day 1 | |
| Total contacts to whom the 1st campaign will be sent to | 100 |
| Hard-bounced contacts in the 1st campaign | 2 |
| Soft-bounced contacts in the 1st campaign | 4 |
| Within 48 hours of the 1st campaign | |
| Total contacts to whom the 2nd campaign will be sent to | 94 |
| After 48 hours of the 1st campaign | |
| Total contacts to whom the 2nd campaign will be sent to | 98 |
| Assuming no further bounces except one contact repeatedly soft bouncing 7 times | |
| Day N | |
| Total contacts to whom the next campaign will be sent to | 97 |
