Happy week after Easter. You likely spent a lot of time preparing for last Sunday and now it's over. Hopefully, you had a lot of guests and collected their information.
I know you're exhausted, but you really need to follow up with these people. You'll be tempted to do something simple like a single "thank you" letter or email to invite them back. But, you worked so hard! Why not take follow up to a new level by setting up a drip campaign to continue to serve them? The difference is bigger than you think and it's easier to do than you think.
