What does CrownSoft do?
CrownSoft makes desktop software for cross-border marketing teams. There are two main product lines.
The first is account filtering. You give it a list of phone numbers, or have it build one from country and area codes, and it checks which numbers are registered on WhatsApp, Facebook, Instagram or Telegram. Its WhatsApp filter can also pull the profile picture and estimate age and gender from it, and it can show when accounts were last active. Results export to TXT, VCF or Excel.
The second is Facebook marketing software. It runs batches of Facebook accounts and automates tasks with scripts, for group, fan page and live marketing.
Who it is for
- Cross-border sales and marketing teams working WhatsApp or Facebook as a channel
- Teams who need to clean a number list before spending on outreach
- Operators running several Facebook accounts on repeatable tasks
What we have and have not checked
We haven’t run CrownSoft’s software ourselves. This page is based on their website as of September 2026.
Messaging apps and Facebook have rules about bulk contact and automation, and those rules apply whatever tool you use. Check the platform terms and the local law on unsolicited messages before running a campaign.
This is a link swap. CrownSoft links to us and we list them here. No money moved either way.
Why pair it with Singapore Mobile Proxy
Checking numbers and running account tasks means a lot of requests to the same platforms. Coming from one datacenter IP, that gets rate-limited or flagged quickly.
Each of our ports exits through a physical SIM in a modem in Singapore, on Singtel, M1, StarHub or Vivifi. It’s a real carrier IP with thousands of ordinary phone users behind the same ranges, and it’s one customer per line. You can rotate it on demand from the dashboard or by API.
How to set it up
- Buy a port on singaporemobileproxy.com. You get a host, port, username and password, for HTTP or SOCKS5.
- Enter those in the software’s proxy settings.
- Keep volume sensible and rotate between batches rather than mid-task.
- For Facebook accounts, keep each account on a consistent IP. Don’t rotate while an account is logged in.
