5 Tools, 5 Inboxes – and Messages Still Get Lost

MedTechnik Hartmann, a 16-person medical device distributor based in Stuttgart, Germany. The support team juggles five different tools daily: Outlook for email, two company phones for WhatsApp, Instagram for product inquiries, and a web form on their website.

Every Monday starts the same way: 45 minutes of triaging which message came in where. Which team member saw the WhatsApp message? Did anyone reply to the Instagram inquiry? Was the web form forwarded?

The result: 12 messages per week fall through the cracks completely. Average response time sits at 14 hours. And when a customer writes on WhatsApp and then follows up via email, they have to explain their issue all over again – because no one has the full picture.

Solution

One Inbox – All Channels, Full Visibility

With SendSeven, WhatsApp, Email, Instagram, Telegram, SMS, and Live Chat all flow into one central inbox. Every message is assigned to a team member, every contact has a complete conversation history across all channels.

A customer writes on WhatsApp, follows up later via email – your team sees the entire history. Routine questions are answered automatically by AI from your knowledge base. More complex issues are assigned based on topic and availability.

The dashboard shows in real time: open tickets, response times, and team workload. No more switching between five apps. No more manual triaging on Monday morning. One screen – everything in view.

Frequently Asked Questions

What is a unified inbox and why do I need one?

A unified inbox brings messages from all your channels – WhatsApp, Email, Instagram, Telegram, SMS, Messenger, and Live Chat – into one workspace. Without one, your team wastes hours switching between apps, customers repeat themselves, and messages get lost. With a unified inbox, every conversation has full history across all channels.

How does automatic assignment work?

SendSeven automatically routes incoming messages to the right team member – by skills (e.g., tech questions to tech), by workload, or via round-robin. Your team sees in real time who's online and available. When handing off, internal notes are included so the next person has full context.

How does AI help my support team?

When a customer sends a message, AI searches your knowledge base and suggests the best answer. Your team can send it with one click or edit first. For routine questions like "What are your hours?" or "What's the delivery status?", AI can respond automatically. Your team focuses on conversations that truly need a human touch.

Is SendSeven right for small teams of 2 to 10 people?

Absolutely. SendSeven is built for teams of all sizes. With automatic assignment and AI handling routine questions, a team of 3 can handle the same message volume that used to require 5–6 people. There are no seat limits on any plan.

How long does setup take?

Most teams are up and running in under 15 minutes. Connecting a channel takes about 2 minutes with the guided wizard. Uploading your FAQ for AI suggestions takes a few more minutes. No developers needed.

What does the unified inbox cost?

The unified inbox is included from Basic (plans from €49/month), with unlimited users and no per-user fees, across all 8 channels. 14-day free trial, no credit card required. See pricing.
