imessage not working with one contact only

How do you use the iCloud address with the contact, there is only one contact that I am unable to iMessage anymore, I've tried resetting the phone, turning iMessage off and on and re entering my iCloud address

I tried deleting the conversation thread with the contact I was having trouble imessaging, then I tried deleting and adding the contact and resetting my network settings and was still having the same problem however I shared my calendar with said contact and once I removed them from my shared calendar the problem disappeared

I didn't want to delete my message thread and adding their email into contacts didn't work, so I figured out another way to get out of green text ****: I signed into iMessage on my laptop and texted the person through there and voila! When I went back into my iPhone, the coveted blue texts returned and I went on to lead my normal life.

Ok, i had to add the email address in contacts to the person it would not send. Then i had to start a new text by typing the email in instead of the persons name. This worked but im really not sure because a week prior i had not problem sending imessage to this person. Hope this helps.

None of this has worked for me :/ anything else I can try?

I tried everything and finally i change the tick next to my phone number to my icloud email under "start new conversations from" under the "send & receive" section in the "messages" area

Have either one of you changed your Apple ID password recently? I was having the same problem and all I had to do was turn iMessage off and then back on in settings and it prompted me to enter my Apple ID password.

Having the same problem and every solution I have found does not work for me. So frustrating!! Even more so, they person can't send a message back to me at all. It says it won't send. I do not have them blocked, yet messages still won't come through. Just upgraded to iOS7.0.6, wish I could go back!!

I am having the same problem. iMessage is working with selective people, but these selective people have working iMessage.

Things I have done to try fix this:

1. I reset my settings on my phone

2. Under settings, messages, I've tried turning off SMS/MMS, changing send & receive around - did not work

3. turned off iMessage and turned it back on again

4. re-booting my phone

5. I completely wiped my phone and restored it

Some of this helpd me fix some of the issue - yesterday my iMessage wouldn't even load - I was getting a network error when I tried too, and I could send a text message (not an iMessage), but I did not receive anything.

Now iMessage only works with selective contacts - doesn't matter if it's the 4S or 5. I know these contacts have working iMessage - because my iPad mini is fine! Same software - and same settings from what I can tell.

Any words of wisdom would help!

I tried everything and what finally worked for me was deleting the message thread and just starting a new conversation with the person

This works

Simply add the e-mail address used to setup icloud of the person in the contacts and voila !!
