Need to make an app to send SMS on The desktop

[omar]

I was hoping someone can point to holes in my plan and give a better solution...

I'm going to write some AHK code to parse through a sales csv and send SMS to customers giving the tracking.

Firstly, I'll read in a CSV file and store the data in an array and have ready for use in memory.

I'll then use windows desktop SMS to send customised messages.
(I'll stagger the SMS sending - I don't want to be flagged up as spam even though I'm sending to my own customers)

I'll use the windows desktop SMS like this:

- alt+f - this highlights the URL and guarantees the actions below lead to the correct buttons.
- tab 4 times. Now I'm in the text entry.
- make bespoke message.
- ctrl + enter. This sends the SMS.
- wait xx seconds.

Is there a better way?
Could I use Javascript just to send the message instead of messing around with tabbing to fields?

Thanks.
