If you are limited to 10 Contacts when using Push to Tout, that is likely due to your ToutApp subscription being on a trial period. During the trial period, users are limited to:
20 emails per day
10 groups, 10 members in each group
2 group emails per day
If you like what you see with Tout and would like to Push more than 10 Contacts at a time via Push to Tout, simply add your credit card information to activate your Premium subscription and we will be able to increase your account limits, which allow for up to 200 contacts using Push to Tout.
