Yotpo: Email Marketing & SMS

The app is good at what it does and seems to be growing. On the other hand some things are frustrating, it falsely reports revenue by changing whatever currency you sell in to dollars without currency conversion. Another issue is you can't pay as you go per sms if you want to do things like birthday messages via reconvert, it forces you into a monthly fee.
EDIT: It went downhill after getting acquired by Yotpo. Syncing is unreliable, support is poor & automations don't always work. Switched to Postcript!
