Whoa, you're on fire!
We love your enthusiasm, but that's a lot of enquiries sent today which means a lot of responses coming your way...
Don't worry, you've done nothing wrong but just so that you don't get overwhelmed with suppliers contacting you over the next few days, we limit the number of enquiries you can make per day.

The quickest way would do it electronically via email, social media messenges or bulk text messaging services. That way its more immediate and guaranteed response acknowledgement. I had a wedding in the past that we had to move the venue due to size restrictions and the couple mailed out the change notifications. Unfortunately a few guests didnt get them in the mail so went to the original venue instead.
