Didn't received the digital ocean droplet root password over email

I didn’t receive any email from digital ocean regarding ip address, username. password.
What shall i do?

Hi ,

Please check your spam folder. In case you din’t find the email. Open digitalocean dashboard and reset the root password of your droplet (server) https://www.digitalocean.com/docs/droplets/resources/reset-root-password/ and you will get the new login credentials of your server over the email.

Do let me know in case you need any other information.

I have received my droplet’s password through mail, but what shall be my username be?
I tried to put my server name, the putty is popping some error. I have attached the pic of it, please check for it.
