Our app can run into timeout errors when too many users are trying to send letters at the same time. We're working hard on expanding our service so this doesn't happen! In the meantime, please try the following:
1. Check your internet connection, or use cell data if your wifi connection is weak.
2. Remove any images from your Letter/Postcard, or try to add smaller images.
3. Try again in a few hours.
If you're still running into a timeout error after trying these, please email us at email@example.com.
