To ensure your subscriber information remains as up to date as possible, Campaign Monitor now allows you to customize how hard and soft bounces are handled for each subscriber list.

This includes setting the maximum number of soft bounces each subscriber is allowed before they are set to an inactive subscriber. You can also customize how this bounce count is affected if a campaign finally gets delivered.

Tweaking these settings allows you to align each subscriber list with your client’s list hygiene preferences.

    I wasn’t sure where to post my question, but I would really like to know the difference between a hard and soft bounce. I’m new to the e-campaigns and I would really like to find an answer to my question through CampaignMonitor whom I trust. Thanks

    Hi Briscoe, no problem at all.

    A soft bounce is an email message that gets as far as the recipient’s mail server (it recognizes the address) but is bounced back undelivered before it gets to the intended recipient. A soft bounce might occur because the recipient’s mailbox is full, the server is down or swamped with messages, the message is too large or the user has abandoned the mailbox. Campaign Monitor will attempt to deliver the email regularly for a few days. If it is still undelivered, it becomes a soft bounce.

    A hard bounce is an email message that has been returned to the sender and is permanently undeliverable. Causes include invalid addresses (domain name doesn’t exist, typos, changed address, etc.) or the email recipient’s mail server has blocked your server. Servers will also interpret bounces differently, meaning a soft bounce on one server may be classified as a hard bounce on another.

    In future, don’t hesitate to send any other questions to support (at) campaignmonitor.com.

    Are these advanced bounce features available in MailBuild too?

  • Dave Greiner

    Hi Erin, to keep things simple for your clients, we stick to best practice defaults in MailBuild and automatically classify an address as bounced after 3 soft bounces in a row. This is the same for all accounts and can’t be customized on a list-by-list basis.
