There are various circumstances under which you might want to resend a message to one or more individual recipients or to one or more groups. For example, several recipients of the original group of recipients appear to have not opened the original message; now, you want to resend the message to this "subset of non-openers."

You can do this in a few different ways in Higher Logic Thrive Marketing Enterprise (Thrive Marketing Enterprise), depending on your situation.

Send to Group: duplicate send rule

Thrive Marketing Enterprise has a built-in mechanism that prevents messages being sent multiple times to your contacts. It does this by matching the message recipients' contact IDs against the message ID. If a contact ID is already associated to the message ID, the message is considered a "duplicate" for that contact and is not re-sent.

NOTE: The duplicate send rule is in effect for one year. After that, the contact IDs are not checked and a message could be re-sent to a previous recipient.

• The next section details two exceptions to this rule, and
• Duplicate send rule workaround describes how to side-step the rule.

Duplicate send rule exceptions

Below are two exceptions to the duplicate send rule.

Sending to an individual

The duplicate send rule (matching contact ID against message ID) is applicable only when sending a message to a group. Messages that are sent to individuals are excluded from this rule.

However, if you are sending a message to a group and you add contacts via either of the Add Recipients options (AdHoc Groups or specifying email addresses), this uses the same mechanism as Send to an individual and bypasses the duplicate send rule.

Consider this when using the Add Recipients options; add only those individuals that you know to not be part of the group or groups to whom you are sending your message.

Sending via Marketing Automation

Marketing Automation does not use the same functionality as sending a message to a group. Rather, messages are sent via a set of rules. Therefore, the matching of contact ID to message ID does not apply.

It is important to note that if a message was sent via Marketing Automation and then sent to the same group (Messages > Send > To a Group), the message will deliver to the contact a second time. Similarly, if an individual meets the criteria for a Marketing Automation campaign a second time (such as for a renewal campaign), messages might be sent to them a second time.

Duplicate send rule workaround

In order to resend a message to the same group, you must make a copy of the message, and then send the copy.

NOTE: This works because creating the copy generates a new message ID that is unique to the copy.

To copy a message and send it:

1. Access the Admin interface.
2. Navigate to Messages > List.

3. Select the message (e.g., Annual Conference) in the list and click More > Save As.

4. On the "copy" dialog, you can either:

• • accept the suggested name (i.e., with (copy) appended) or
  • specify a new name (e.g., 2025_Annual Conference) for the copy.

5. Click Create Copy.

Review the list to confirm the new message is listed.

6. Select the message and click Send > To a Group to send the new message to the group.

Marketing Automation auto-resend options

In addition to the workaround that is described above, there are a few ways to use Marketing Automation functionality to automatically resend a message to select recipients.

• Send the message in a campaign. Then send the message again but with a filter that excludes any recipients who have previously opened it.
• Create a campaign that enrolls recipients from a group, with the filter that they were sent a message but did not open it.
• Create a Saved Search for recipients who were sent a message but did not open it, then use that to create a new campaign.
• Create a Saved Search for recipients who were sent a message but did not open it; add the results to a group, create a copy of the message (as described in the "workaround" section above), and send the copy to a group.
• Create a Workflow Builder campaign that does some combination of the above.
