If you have encountered bounced emails in your Alchemer Email Campaigns, you may be wondering what effects this has on that campaign and future email campaigns. Below, you will find some information that should help!
Soft Bounce v Hard Bounce
A hard bounce is an email that has been returned by the recipient's mail server as permanently undeliverable. This can be caused by invalid addresses (domain name doesn't exist, typos, changed address, etc.).
A soft bounce is an email that gets as far as the recipient's mail server (it recognizes the address) but is bounced back undelivered before it gets to the recipient. A soft bounce might occur because the recipient's mailbox is full, the server is down or swamped with messages, or the message is too large. Soft bounces can also include things like auto-replies to your email. Soft bounces should eventually change to Bounce (which is a hard bounce) or Sent.
Servers can sometimes interpret bounces differently, meaning a soft bounce on one server may be classified as a hard bounce on another.
How do I know if an email is bounced?
Bounces will display on the Delivery Statistics section of your email campaigns and will populate in the message status fields of the status log (downloadable via Export Contacts with Send Status on the Delivery Statistics page). Because our system retries soft bounces this status is temporary so you won't encounter it very often.
To identify which email addresses bounced in a campaign, go to the Delivery Statistics step of your email campaign and click the option to Export Contacts with Send Status. For each email message, you will have a Send Status column. Simply sort by this column to quickly see a list of all bounced emails.
Email addresses that are listed as Bounced for any given message's Send Status will not be eligible for further sends of subsequent Reminders or Thank You messages.
You can actually take advantage of this to clean your contact list for your next email campaign! Simply delete these contacts from your spreadsheet when you're ready to send your next campaign.

Correcting Bounced Email Addresses
If you determine that the reason your email message bounced for a given contact is the result of an incorrect email address you'll need to re-add this contact and re-send your invite messages. Unfortunately, correcting the typo in the existing contact will not correct the issue.
How do bounces affect my email campaigns?
Bounced emails can affect your campaigns in a couple of ways:
- We run a health check on all campaigns by first sending to a random 5% sample of the list. If the bounce rate of this sample is higher than 10%, we will cancel the send and alert the user who created the campaign via email. If the bounce rate is below 10%, up to 5,000 messages will send every 30 minutes until all messages are sent. Learn about best practices for avoiding campaign cancellation.

- If an email address has bounced, you will not be able to add that email address to a Alchemer email campaign for a period of 30 days.
