Hard Bounces, Soft Bounces - how are they tracked?

Posted on by 125

Dear microsoft dynamics marketing community,

do you know how hard and soft bounces are technically tracked in dynamics marketing? eg how are the mail server responses interpreted?

I know the documentation about "maximize email deliverability" (https://docs.microsoft.com/en-us/dynamics365/customer-engagement/marketing/get-ready-email-marketing) but do not find enough information there.

Thanks for your help!

    Yes, this was from the link listed above.

    Here it is again for your reference:

    "Dynamics 365 Marketing will automatically stop sending to hard-bouncing addresses for six months before trying them again."

    docs.microsoft.com/.../get-ready-email-marketing

    Located in the "Avoid sending to invalid and inactive email addresses" section.

    Hey - do you by chance have a link to where it says the 6 months timeframe? This makes me very worried!

    Above was stated: When an address returns a hard bounce, Dynamics 365 will automatically stop sending new messages to that address for six months, but your email results will still show each attempt as a hard bounce.

    So does that mean that for the 6 months after the email address hard bounced, delivery won't be attempted with that email address (and hence not impact sender reputation) however the stat will still show up as a hard bounce on the insights tab?

    Do we need to manually do anything to permanently remove/delete/deactivate hard bounces from our lists or does the system action this automatically?

    So continuing on from Megan's comment.

    A email that is bounced back from the customer's mail server will appear as a bounce. An email that ends up in the customer's spam folder will not be recorded as either a hard or soft bounce as the mail server accepts it (so its not a bounce). Only after accepting it does the server decide which folder to put it in.

    This is why mailchimp and others focus separately on spam as it's an issue with the content of emails they cannot control rather than a settings / identification issue which they can control.  mailchimp.com/.../avoid-spam-filters is a good place to start reading..

    Hi Carolin,

    You can find further information on the following link: docs.microsoft.com/.../insights

    The below is regarding the tracking:

    Bounced (hard)

    Messages that resulted in a hard bounce, which indicates that the address is invalid. A hard bounce might occur because the domain name doesn't exist or because the recipient is unknown. Multiple hard bounces can lower your server's send reputation, which will reduce your delivery rate, so you should remove hard-bouncing addresses from your contact records. When an address returns a hard bounce, Dynamics 365 will automatically stop sending new messages to that address for six months, but your email results will still show each attempt as a hard bounce.

    Bounced (other)

    Messages that bounced for some reason other than a hard or soft bounce. This result is rare, and might indicated a remote bounce, which occurs when a server initially accepting a message, but then returns a bounce message sometime later. These are otherwise treated as soft bounces.

    Bounced (soft)

    Messages that resulted in a soft bounce. A soft bounce occurs when an email is sent to a valid server, which recognizes the user, but still rejects the message for some reason, such as because the recipient's mailbox is full, the mail server is temporarily unavailable, or the recipient no longer has an email account at that address. If five messages in a row sent to a given address result in a soft bounce, then that address is treated as a hard-bounce address.

    I hope this helps.

    And how does Dynamics react, if the Email is not coming through the Spam Filter?

    If the Marketing Email is not coming through the Spam Filter ? Is it then marked as Hard Bounce although the email would be valid but the spam filter rejected it?

    Can the sales person then still send his mails to the contact?

    Can I download a report about the bounces somehow?

    They are logged as interactions in the marketing customer insights against the contact/journey/email.  If a contact hard bounces, then it will be blocked until the email address is changed, and then it'll try again.
