In case you want to use the same message in multiple campaigns, you don't need to copy that manually. You can easily copy whole sequence, here's how:
Access the Sequence Tab:
Navigate to the sequence tab within the project you want to copy message into
Copy Existing Messages:
Select the “copy existing” option.
Choose the project from which you want to copy the message.
Click on "copy sequence" to finalize the action.
The messages will upload immediately into your new project. Once the messages are copied, you can edit them as needed.
You can also add more steps into your sequence to customize your outreach further.
