email from echosign@echosign.com

Hi, I have received this email from echosign@echosign.com:

"Dear xxx,

Your Adobe ID xxx was recently used to access the Send for Signature or Create Sign Template functionality within the unified Document Cloud. An Adobe Sign account with the same email address already exists. To protect your signed agreements, we request a one-time verification to confirm your identity.

Please enter the verification code below to authorize access to your Adobe Sign account from within the Document Cloud user interface.

Verification Code: xxx

IMPORTANT: If you did not request access to the Adobe Sign functionality in the Document Cloud user interface, or believe you have received this message in error, please contact Adobe Support.

Regards,
The Document Cloud Team"

I haven't requested access to Adobe sign, hence the following questions:

- is this a genuine email / scam?

- if genuine, how can I contact adobe support?

Thanks in advance for your help
