I need to send an email.
To sign this, start with 'I', then 'need', followed by 'send', and finally 'email'. When signing 'send', ensure your dominant hand moves outward from your body to show the email going out to someone else.

Did you send the package?
Sign 'you', 'send', and then 'package'. Since this is a yes/no question, remember to raise your eyebrows and lean slightly forward while signing to indicate that you are asking for a response.

Please send it to me.
Because 'send' is a directional verb, you can change its movement. Instead of moving your dominant hand outward, start the sign slightly away from your body and bring it inward toward yourself to mean 'send to me'.
