When an official (legal) form states block capitals, does that apply to the email address too?

Writing in block capitals makes it easier to read and reduces mistakes.

That would also apply to writing out an e-maol address.

Email addresses are not case-sensitive...so it doesn't matter if you use them (or not!)

It might be machine read, so capitals makes it more likely to be accurate.

[Peter Pedant]

ginge is right

Technically the bit before the @ in an email address is case sensitive but pretty well nobody enforces this; from Wikipedia regarding the RFC5322 standard “ An email address, such as [email protected], is made up from a local-part, the symbol @, and a domain, which may be a domain name or an IP address enclosed in brackets. Although the standard requires the local part to be case-sensitive,[1] it also urges that receiving hosts deliver messages in a case-independent manner,[2] e.g., that the mail system in the domain example.com treat John.Smith as equivalent to john.smith;”

All that 'write in block capitals' means on any form is 'write clearly'. You won't invalidate the form if fail to use capitals.

My own preference, on the rare occasions that I've encountered similar instructions, is to use block capitals throughout except for my email address, where I simply print each letter separately (and very clearly) using lower case.
