Use Drafted templates but send email through your own personal account, to get the best delivery, tracking, and response rates. Drafted doesn't read the contents of the emails in your inbox and uses best-in-class security and authentication, so your IT department will be happy too.
Sending direct email is the best way to get in touch with your candidates. Spend your time where it counts.
Create personal templates based on how connected the candidate is to your company. Do they know several people on the development team? Create a template for that type of connection.
