Frequently Asked Questions

Everything you need to know about LeadNest. Can't find the answer you're looking for? Reach out to our support team.

How does the 'Pay-as-you-go' Wallet work?

You top up your LeadNest Wallet with credits (e.g., $50). Every time you send an email ($0.001) or a WhatsApp message (Meta's rate + minimal markup), it deducts from this balance. You see the exact projected cost before initiating any campaign.

Do I really not need to pay for Zoom or Calendly anymore?

Correct. LeadNest Meet provides unlimited high-quality video conferencing, and Schedule Nest gives you a complete booking link system. Both are included natively.

Can I use my existing WhatsApp Business number?

Yes! As an official Meta API provider, we can migrate your existing WhatsApp Business number to LeadNest seamlessly without downtime.

Is there a unified API?

Absolutely. We provide a single REST API that allows you to trigger emails, SMS, WhatsApp messages, or update CRM records without managing multiple different provider SDKs.

What about email deliverability and domain reputation?

LeadNest includes built-in email infrastructure with SPF, DKIM, and DMARC configuration. We help you maintain strong sender reputation with real-time monitoring and best practice recommendations.

Can I import my existing contacts and data?

Yes. You can import contacts via CSV upload or connect directly to your existing CRM. We support bulk imports and provide data mapping tools to ensure everything transfers correctly.

Is my data secure and compliant?

Security is our priority. LeadNest is SOC 2 compliant, uses end-to-end encryption, and follows GDPR, CCPA, and other data protection regulations. Your data is stored securely and never shared with third parties.

What kind of support do you offer?

We offer 24/7 email support for all users, live chat during business hours, and dedicated account managers for enterprise customers. Our comprehensive documentation and video tutorials help you get started quickly.
