I think it's working.  I received that email from BandLab however, I had not been getting regular emails from Cake in years.

I believe you can also change the email address in your BandLab account settings. When I signed up with BandLab I used the Login with Facebook option - which is a different email address. I went to my account settings in BandLab and now it points to the same email as Cakewalk. I think I had to reset my password at that point since I was no longer connecting with Facebook.

Yup, in gmail Spam folder... 

Just checked my Cakewalk account and it does have the correct email address but I have not received an email yet from Bandlab.  I did went ahead and created an account on their site. Is there anyway on the Bandlab account info to indicate whether or not you are a ex-Sonar user?
 
I just hope that I get an email when the new version of the new DAW that was named Sonar is ready.

I don't see any note or labels showing we're Cakewalk / SONAR / TDFKAS users. Hopefully there will be something once they've migrated the Cakewalk user data.

Another found in my Gmail spam folder.

Yep, based on this thread, I just checked and my email was in the spam folder in Gmail.  This could be a problem for some users.
 
I had already created a Bandlab account using the same email address as my Cakewalk account but I cannot see anything in the Bandlab account settings that refers to this:
 
For the thousands of Cakewalk users who have already signed up for BandLab with the same email address as your Cakewalk account: you don’t need to do anything, we’ve already tagged your Cakewalk ID to your new BandLab account!  
 
It would be good if there was some form of confirmation on the Bandlab account that this process had been successful, perhaps referencing the Cakewalk ID?
 

I have signed up for BandLab with the same email address as my Cakewalk account on 21st March and have not received notification of 'Cakewalk by BandLab'.

I do not believe the sent e-mail about the early release. I expect they will send e-mail when the early release program is over. You can wait until then or download BandLab Assistant now and get the early release version of Cakewalk by BandLab.
