Simple Bulk Messaging Software

We need a PC Windows software for bulk (mass) advertising messages to bulk mobile phone contact list via follow messenger mobile application or chat services. The software (script) can run under Windows and should have a difficult locking protection for copy right. Whole system must be deliver to me in full open source with very good comments and documentation for trace or changing in future. Freelancer must expert in API for chat, message service (no call or video call required). Also need to study and research API for PC programming: Telegram, [url removed, login to view] . The process of sending bulk messages is as follow:

1- LOGIN: • Each clients, login to his account from the software, the software should connect to our mysql database (server side codes are ready to use now) and should register by their names and after that waiting for activation from the admin (sample projects already done and can be showed to freelancer to speedup the job)

2- CONTACT LIST: Contact list are bulk mobile number files (TXT or EXCEL).

3- SENDING SERVICES: Select the method of sending bulk messages to contact list: Telegram or imo

4- FILTERING PROCESS: Software automatically check, filter and save which phone number in CONTACT LIST having these SENDING SERVICES separately vs. sending services.

Also user must be able to filter a given phone list manually and export them in TXT or Excel Format.

In this process, if phone number include (have) the service, then must send an API request and get user profile information of contact list. In each services, the user profile information is different (First Name, Last Name, Name, User ID, profile picture, status, gender, geo location, email, address, last seen, …). These profile information must save and client can use them as variable in text.

For filtered (checked files) & saved contact list, checking again is optional. The total filtering rate is around 3 million phone numbers/day or more (totally)

5- SENDER PHONE NUMBERS: There are two group sender phone numbers:

• Private phone numbers for each client. Each client can able to add his sender phone numbers to sender list.

• Common phone numbers for all client. The timing of sending depends to submit time and approved with admin. Free virtual phone numbers generator are optional. Sending phone number is around 1 million (Totally). For each sender phone numbers, client can use picture profile, name and … according to SENDING SERVICE.

6- Bulk Sending Methods: Some SENDING SERVICES accept sending to one contact or group or channel. Client can select like to send one to one, or one to group or one to channel. In these case script at first generate a group or channel then send to it. The methods of sending must not detect as spam by SENDING SERVICES. Sending per phone number in each day must adjustable. Anti-spam detection is necessary and essential for each SENDING SERVICES (i.e in Telegram, Changing the IP and Mac Address etc).

7- ADVERTISING CONTENT: client can write his advertising messages include text and pictures or stickers, links and contact user profile variables. For example: Dear [user_ID]

8- REPORTS: Reports include fail sender phone numbers, messages sending, messages delivered, and messages seen (if possible). Payment and credit report

9- Payment: Client can pay fund to buy private sending phone number, or cost of sending messages… (this step is paused for now)

10- All strings and texts an messages should be easily translatable in other languages and fully RTL supported (i.e for Arabic)

11- Support on this system as a working system must be applied by at least 3 months from freelancer
