Customer Support Teams
Support teams juggle physical phones or browser sessions that log each other out, leading to slow replies and lost conversations.
Resend consolidates official WhatsApp numbers into a shared multi-agent workspace with live chat assignment, resolution statuses, and canned templates.
Eliminate duplicate responses, establish clear agent accountability, and cut first-response times from hours to minutes.
B2B Sales & Inbound Leads
High-intent inbound leads drop off when directed to slow email forms or delayed callback requests.
Capture leads directly on WhatsApp, qualify their requirements via interactive chatbot buttons, and instantly route qualified leads to the assigned sales rep.
Engage prospective customers in real time where they already communicate, accelerating qualification and discovery calls.
Marketing & Product Broadcasts
Email marketing open rates continue to decline, while informal WhatsApp broadcasting risks sudden number bans.
Deploy official Meta-approved template broadcasts with rate limiting, variable personalization, and segmented recipient tags.
Achieve verifiable delivery rates across verified customer databases without compromising phone number standing.
24/7 Conversational Automation
Common repetitive questions (store hours, order status, return policies) overwhelm human agents during off-hours.
Deploy visual chatbot flows and keyword triggers that handle immediate answers, list pickers, and automated resolution paths.
Resolve standard inquiries automatically while reserving human agents for complex escalations.
Agencies & Multi-Client Operations
Agencies managing WhatsApp for multiple clients suffer from account credential leakage and cross-client data confusion.
Multi-workspace isolation allows agencies to run independent client numbers, dedicated team seats, and separate billing accounts.
Keep client assets strictly isolated with individual audit logs, webhook endpoints, and tailored subscription tiers.
E-Commerce & Developer Integrations
Order dispatch updates, OTPs, and payment receipts are disconnected from the primary CRM and communication tools.
Our developer REST API and secure webhook events enable two-way sync with Shopify, WooCommerce, or custom backend services.
Automate transactional notifications directly through WhatsApp and allow support agents to view order context in real time.
Predictable Pricing. Zero Hidden Fees.
Powered directly by our production billing engine. Upgrade, downgrade, or adjust licenses anytime with full prorated balance management.

Frequently Asked Questions
Clear, honest answers about our WhatsApp integration, multi-agent collaboration, and billing.
What is Resend?
Resend is an official B2B customer relationship management and team inbox platform for WhatsApp. It allows teams to consolidate WhatsApp conversations, automate routine interactions, run broadcast campaigns, and collaborate seamlessly from a single workspace.
How does WhatsApp integration work?
Resend supports direct integration with Meta’s official WhatsApp Business Cloud API for enterprise deliverability and high message limits. For businesses with existing numbers, we also offer high-speed QR instance connectivity for rapid setup.
Can multiple agents respond from the same number?
Yes. Your entire team can log in simultaneously, view shared customer conversations, assign chats to specific agents, add internal collaboration notes, and reply without disconnecting other agents.
Can I connect multiple WhatsApp numbers?
Depending on your subscription tier, you can connect multiple official WhatsApp numbers to one central workspace and route incoming conversations by department (e.g. Sales, Support, Operations).
What is the difference between Cloud API and QR instances?
The Meta Cloud API connects directly through Meta’s servers, ensuring official verification, zero dependency on a physical phone, and unlimited scalability. QR instances allow quick connection of standard WhatsApp accounts without undergoing business verification.
Can I send marketing broadcasts and campaigns?
Yes. You can broadcast Meta-approved template messages to segmented contact lists. Resend includes built-in rate limiting and delivery pacing to protect your account health and reputation.
Can I automate conversations without code?
Yes. Our visual Flow Builder and keyword chatbot rules enable you to create automated multi-step decision trees, menu options, button replies, and conditional branches with an intuitive visual editor.
Does Resend have a Developer REST API?
Yes. Our public REST API (v1) and HMAC-SHA256 verified webhooks allow you to send messages, manage contacts, query analytics, and trigger external workflows from your internal systems, CRM, or e-commerce store.
How does billing work and can I cancel?
Billing is transparent and calculated using real-time SaaS rates. You can choose monthly or annual billing directly from your workspace dashboard, and upgrade, downgrade, or cancel your subscription at any time with prorated adjustments.
How does the free trial work?
New workspaces receive a 10-day trial with full access to test the multi-agent inbox, connect a WhatsApp number, build automated chatbot rules, and explore all core capabilities before committing.
