You are trying to add a new stream to an Engagement Program but get an error stating that your program has reached maximum number of streams per program.
Due to engineering constraints and as well as to have better user experience, we have limited the number of Engagement Program Streams per program to 25. When you try to add 26th stream, you will now get the error message “You have reached the maximum number of streams. Create another program”. So the solution is to create a separate Engagement Program and a Smart Campaign that moves leads from the original Engagement Program to the new one.
