Not able to see semi colon and comma while sending email

The semicolon and comma are on the numeric keyboard.

Click the "123" key in the lower left and then you will see them.

UPDATE: The above is true while in the text area. Sorry I misread your question and thought that was what you were asking about. The semicolon and comma have no function in the addressee area.

The plus + sign works in all cases - whether you have contacts saved or not. Type in any an email address (doesn't need to be valid) - tap the + button. This will bring up your contacts - simply close the contacts search - type your second address - repeat this process for more email addresses. I agree - it is a bit awkward - but that is how it works - a comma or semi-colon list would be easier. It is not immediately apparent that the contact search is not requiring you to select a saved contact - rather it is simply offering to allow you to search for those contacts that you have already saved.

This is an absurdity to the flow of the keyboard. clicking the plus sign opens the address book. what if you just want to add a comma and scribe another address in?

Sometimes I wish I had a clue as to the thinking of the "engineers" behind this stuff.

In the Mail app on iOS devices - the keyboard does not show semi-colons or commas. If you need to enter multiple email addresses in the To: field - there is a + (plus) sign at the far right of the To: box. Click the + to add additional email addresses.
