What's a "bounced email"?
A "bounce" is when Envoke tried to send an email and it failed to go through due to some issue on the recipient end (incorrect address, network error, mailbox full, etc.).
Contacts that bounced many times are marked with an "Invalid email" and they will be excluded from future email e-blasts automatically.
It is not uncommon for addresses that previously worked to become invalid (for example, an employee's mailbox may be disabled if they leave the company). Occasionally, this may happen due to a temporary issue with the mailbox.
If an address has been marked as invalid and the issue with the mailbox is subsequently resolved, you can reset that contact's fail score (which keeps track of sending issues) and Envoke will try to deliver emails to that contact again.
Bounce management is automated
Bounced emails are automatically excluded from future e-blasts as it's best practice not to keep sending to known invalid emails. You don't need to manually remove or exclude these contacts.
Bounced emails are not deleted from the database so you have a record of them. Deleting would also mean skewed and inaccurate reports.
Bounced emails don't count towards the number of active contacts so you're not paying for these contacts: The monthly subscription fee is based on active contacts only and since emails aren't sent to these contacts they don't use credits if you are on the pay as you go billing plan.
Bounce vs. spam
Spam filtering happens on two levels. The first round of spam filtering is performed by email servers. Emails rejected by mail servers are considered bounces.
If an email passes the mail server's spam check - and other checks to ensure the email is valid in the first place - then the email is considered delivered. At this point a second round of spam filtering takes place by the recipient's email program. This determines if emails are placed in the inbox or in the spam folder. If the email is placed in the spam folder at this point it is not considered a bounce. Also, since this happens after the email is delivered there is no way to report on it.
Impact on your account
High bounce rates can create deliverability issues as too many bounces are an indication of poor list quality or sending unsolicited emails.
Bounces are not the same as consent
Bounces are a technical issue, not the same as consent status, which is managed by contacts indicating their opt-in status. For example a contact can have express consent and bounce at the same time.
Types of bounces
There are two types of bounces: A hard bounce indicates a serious issue that is unlikely to be resolved, for example an invalid email. A soft bounce is less serious and often temporary. Examples of soft bounces are: mailbox full or server down.
Bounces are tracked for each individual contact record for email campaign you send.
A fail score is maintained for each contact record in your account. Fail scores start at zero for each new contact that's added to your list and they are increased when bounces occur: fail scores are increased by one for soft bounces or more than one for hard bounces. When a contact's fail score reaches a threshold it will automatically be marked as an invalid email.
Reporting on bounced contacts
The database overview page shows how many contacts are marked "invalid" due to too many bounces.
For each contact the following metrics are available related to bounces:
Fail score: A numerical value, starting at 0. It's increased with each bounce.
Failures: Shows how many times an email bounced.
Send email: A yes/no marker that determines if an email is in good standing. If a contact's "send email" field is set to "no" you cannot send emails to that contact.
Resetting the fail score
You can reset the fail score of a single contact from the contact details page using the "Reset" link. Fail scores cannot be reset in bulk.
