CW‑WhatsApp Chat, Abandon Cart

Simple and useful app. I was using another app earlier who were not responsive. Someone from this app team called next day to confirm if everything was fine and if we faced any issues.
You can customise templates.
They provide some free SMS credits when install the app to test it out.
You can have your own sender id
I liked that you can customise any sms template
Interface is also clean and neat
There is an option to send Marketing sms though I have not used it yet

Also for those who are not clear on charges (I was not clear) - You have to recharge some amount (minimum is $30) and then your balance will be deducted as the SMS is sent according to the SMS charge for the country.

Overall good App.
