I always use to prefer email marketing over other channels because it was very cheap! So far so good with smarp message as well!! It's quite expensive compared even though its easy for me to understand their business purpose behind this product which made more attractive in my opinion especially if you have limited budget or small startup/mampus team then smartmessage would be nice option. You will like once u start using your target audience are easily connectable through messenger than only emails. ! Good thing i am working at global bank (fina) who has great relationship between SMB clients from different countries hence able to send them messages via smartmessge channel without any problem. !! The best thing about SMARTMESSAGE so far has been how easy it was to use this tool in order to send messages from our database straight into recipients phones! I have not found anything yet that isn't great about using SMARTMESSSO for marketing purposes. We are able to reach out to many customers with ease right at their fingertips. This saves us time as well since we no longer need to manually update lists or call people up every month or two to remind them about upcoming events.
