Frequently Asked Questions

Yes, FlashSender is completely safe. All your data is encrypted and protected under strict privacy policies. We do not share your information with third parties.

We follow WhatsApp's terms of service and implement smart delays between messages to prevent account restrictions. Our tool mimics human behavior to ensure your account stays secure.

However, using it for spam or unsolicited messages may lead to your WhatsApp account being suspended or permanently banned.

Our WA Links Hunter searches for public WhatsApp group links from various search engines based on keywords you provide. It helps you discover communities relevant to your business where you can engage with potential customers.

WA Fetch Contacts allows you to easily extract and copy contact information from public WhatsApp groups that you can already see. This feature only makes it convenient to collect contacts that are already visible to you as a group member - it doesn't access private or hidden information.

Our SMS messaging feature uses Hubtel API integration to send bulk SMS messages to your contacts. This works similarly to our WhatsApp bulk messaging but reaches customers via SMS, giving you broader communication coverage and ensuring your messages reach customers even when they're not active on WhatsApp.

Absolutely! FlashSender allows you to create personalized message templates with dynamic variables like names, companies, and custom fields. You can also send different messages to different contact segments across both WhatsApp and SMS channels.

The Free plan gives you 100 WhatsApp messages and 50 SMS messages per day forever, perfect for small businesses. The Premium plan offers unlimited messages across both channels and priority support for growing businesses.

Most users see immediate results after their first campaign. With our high delivery rates and targeting capabilities across WhatsApp and SMS, you can expect responses within hours of sending your messages.

No! We do not offer refunds for Premium plan purchases. Since all features are unlocked except unlimited messaging, we encourage users to explore the app thoroughly with the free version and upgrade only after they are confident it meets their needs.
