If people are not texting in the keywords do not worry. Keywords are just an added feature for tech-savvy users. Connection cards might be the way to go for your congregation. You certainly do not need to use our keyword feature. How you gather folks' information is not nearly as important as how you follow up with them once you have it!
We recommend doing both paper connection cards and digital connection cards (text a keyword or use a digital connection card link) as you just never know who will be more comfortable with what and you want to reach the most people possible.
Also, have you began communicating with your members yet? Try sending out a few texts message to promote your next church event or sermon series. Sometimes it might just take a while to gain their confidence and trust in the new system!
