Whatsapp bulk mass sender software

We need a software that can filter mobile numbers (around 3 million) from a list, then

send messages (text + image).

We believe that out of these 3 million mobile numbers that we have, 800 thousand have an active Whatsapp account, we need a software that can filter the Whatsapp users and them send the messages.

All the mobile numbers are from the Czech Republic, they are all local numbers.

We would like to send around 30/40 thousand messages per day until everyone receives the offer (coupon).

I must mention that all these numbers are legit and legal, they are (or were) our customers. All these people that we will filter that will have an active Whatsapp account, we will send first an email mentioning that they will receive a coupon via Whatsapp, this people will be expecting the coupon, hence, the software must work!

+++++++++++++++ VERY IMPORTANT +++++++++++++++++++

Dear Freelancer,

You need to deliver the software and let me test it ++BEFORE++ payment is released because I need to verify that messages get to phones in my area.

a) If you do not have experience in this kind of project please don't bid, PLEASE don't waste yours and my time.

b) We do not care if your solution is web based or downloadable SW, we just need something that works!

c). The list of contacts should be read from a plain text file.

d). Must be able to use several senders (channels) also loaded from a text file.

e). Reports need to show how many messages are successfully sent.

f). Your app or software should not require serial numbers or any form of license.

g). Payment will be made only after the software is delivered and fully tested.

If you are reliable and make this work, we will have ongoing work for you.
