An easy way to let others know about your new mobile event app is to include the download link or QR code to the mobile app in your email signature. You can set up a personalized email signature in your settings so it’s automatically inserted at the bottom of each email you send. For the best results, include these two things in your customized signature.

1. The link or QR code to download your mobile event app

2. A link to your event's website

Including these two things in your signature is a simple way to promote your event and mobile event app without sounding too forced or aggressive. Adding a short sentence or tagline before the links might also motivate people to click on them. Something simple like, "Check out our new event app" or "Enhance your event experience" might be enough to spark curiosity. Think about what would make people want to click on your link.

Does your organization send out a monthly newsletter? Plan this out in advance so you can devote a section in the newsletter to your event app. Even better—make the entire newsletter about your new mobile app. This is the time for you to hype your event and show how your app will make the experience even better.

You could even start a weekly email campaign to help people understand how to use the app effectively. Create a subject line with a call to action, like “Simple Tips on How to Use Your Event App.”  Or maybe you want to come up with 3 benefits for each email and call it, “3 Ways to Use Your Event App Effectively.” Think about it like this—what would make you open that email?

A weekly email campaign also requires more planning. Brainstorm topic ideas and run it by other people in your organization to see what generates the most interest. Think about your event and audience. Are people more concerned with how to find specific speakers? Or would they be more interested in customizing their schedules, taking notes, and sharing their thoughts with their social networks? Include whatever you think would inspire people to use your mobile app before, during, and after the event. If your attendees see this as valuable, they'll be more likely to download and utilize the  app.
