To move failed subscriptions from one autoresponder to another:

1. Create the destination autoresponder and set its status to Sending Paused or Disabled

2. Create a segment that will filter those failed subscriptions 

3. Filter your contacts list using the segment you created

4. Once the filter is in place, choose Edit matching contacts from the I want to... drop-down menu

5. On the Edit Matching Contacts screen, select the following under the Subscription section:

For autoresponder: choose the originating autoresponder – where you are removing them from

Move to this autoresponder: choose the destination autoresponder – where you are transferring them to

You can leave the rest of the fields as is.

6. Click the Save Changes button
