Suggestions for text autoresponder for Open Houses

Hi everyone. My office does a lot of open houses and we generate a lot of listing opportunities with future sellers stopping by to talk. There are 2 things I would like to do to get more sellers to visit…

  1. We mail out a monthly real estate newspaper. I would like to include an advertisement that says something like “Text Home to 99999 for an updated list of open house times and locations.”

  2. I would like to do a similar CTA to include on our open house signs. We often do several open houses in the same neighborhood so the signage can be confusing.

Can anyone give me any suggestions about how to create a page that would be easy to update so the text autoresponder will send them to that page?
