Just sent a letter of application via email (the careers page on the website gives you a HR email address rather than postal address to send applications to)
Just realised that I haven't included my postal or telephone contact details
, have I screwed up, I'm not sure whether they would want to use a different contact method than email for replying to it?
What should I do?
