Challenges

7 problems agencies must solve in 2026

The agency market is changing faster than ever. These pain points affect digital agencies across all segments: from dialogue to performance to e-commerce.

01
According to Gartner, by 2028 around 90% of B2B purchases will be mediated by AI. McKinsey confirms: companies are increasingly automating marketing tasks. Clients are questioning the value of traditional agency services: from content creation to social media management to paid search. Agencies urgently need services that can't be replaced by AI: an active WhatsApp channel with strategy, setup, ongoing optimization and AI-powered automation.
02
Customer acquisition costs have risen by over 222%. CPMs on Meta and Google are increasing by double digits. Instagram alone was at €8.70 CPM in Q2 2025. For performance and social agencies, paid reach is getting more expensive, and every click must convert. WhatsApp and Browser Push are owned channels: subscribers acquired once can be reached without additional ad costs. Those who buy directly: perfect. Those who have questions get consulted in chat and guided to a decision.
03
Clients are actively asking for WhatsApp marketing and multi-channel solutions. Agencies without a matching offering lose pitches, and existing clients along with them. Competitors who have WhatsApp broadcasts, interactive quizzes and sweepstakes in their portfolio win the deals. The portfolio pressure grows with every quarter in which your agency can't offer these services.
04
Email open rates sit at 17–22% across industries and continue to decline, accelerated by Apple's Mail Privacy Protection, which has been distorting open rates since 2024. New subscribers are harder to acquire. Campaign reports show declining metrics that are hard to justify in quarterly reviews. Clients are looking for complementary channels: WhatsApp delivers 98% open rates, Browser Push reaches 15–20% without an email address and without ad costs.
05
Similar agencies everywhere: same channels, same tools, same pitches. Those who offer WhatsApp marketing, interactive quiz campaigns and sweepstakes as a standalone service create a genuine differentiator. New channels like Click-to-WhatsApp Ads or Browser Push campaigns are often beyond competitors' capabilities, and this is exactly where differentiation happens.
06
One-off projects dominate, recurring revenue is missing. Clients see no added value in traditional single-channel campaigns (email, social posts, display ads). An ongoing messaging service (WhatsApp campaigns, sweepstakes, quiz funnels, AI chatbot management) creates predictable revenue of €1,100–€1,700/client/month and long-term client retention instead of project-based churn.
07
Traffic is being generated, but the right channels for the last mile to purchase decision are missing. Forms on landing pages convert at 3–5%. Click-to-WhatsApp Ads route prospects directly into a chat. The AI chatbot qualifies, advises and collects contact data. Browser Push reaches website visitors without an email address at 15–20% open rates. No form, just conversation.
01 / 07
For every agency type

5 agency segments, one shared lever

Whether your agency specializes in dialogue, CRM, performance, social media or e-commerce, multi-channel messaging fits every portfolio.

01

Dialogue & Newsletter Agencies

Already strong in 1:1 channels. WhatsApp is the natural next step: 98% open rate vs. 17–22% for email. Plus AI-powered bots and Knowledge Base as an additional service.

„Same logic, new reach: WhatsApp delivers up to 5x higher engagement rates.“
02

CRM & Automation Agencies

Automation flows are often email-focused. SendSeven extends CRM workflows with WhatsApp as a touchpoint via n8n, Make.com, Zapier or REST API. Quizzes achieve ~30% opt-in rates for lead qualification.

„Turn a CRM event into a WhatsApp message: integration in under one hour.“
03

Performance & Lead-Gen Agencies

Click-to-WhatsApp Ads (CTWA) turn Meta campaigns into conversational funnels. Browser Push offers free retargeting at 15–20% open rates. Owned reach instead of rising CPMs.

„Those who convert directly, perfect. Those with questions ask them via WhatsApp.“
04

Social Media Agencies

Instagram DMs, Facebook Messenger and WhatsApp in one Unified Inbox. Interactive formats like quizzes, sweepstakes and product consultations directly in chat, beyond content posts.

„Instagram, Messenger and WhatsApp in one inbox, plus interactive campaigns as a new service.“
05

E-Commerce Agencies

WhatsApp newsletters with opt-in directly in the shop: shipping notifications, re-engagement and personalized recommendations. ~€0.11 per template, but 5–8x more revenue per euro invested than email.

„WhatsApp and Browser Push as a combination of high engagement and low cost.“

FAQ

Frequently asked questions

How do agencies make recurring revenue with SendSeven?

By packaging messaging as a managed retainer. Agencies run WhatsApp campaigns, interactive quizzes and sweepstakes, Click-to-WhatsApp ads, AI chatbots, and Browser Push for each client as an ongoing service, typically €1,100-1,700 per client per month. Instead of one-off projects, you build predictable monthly revenue and stickier client relationships across every channel in one platform.

Can I manage multiple clients separately in one account?

Yes. Custom Inboxes give each client its own inbox, and team members only see the clients assigned to them, a sub-tenant experience without multi-tenant overhead. Contacts, campaigns, and analytics stay cleanly separated per client, and data isolation between tenants supports Art. 28 GDPR processing. One agency login manages every client from a single platform.

What does SendSeven cost for agencies and how do we price it?

SendSeven starts at €49 per month (Basic plan), with usage-based messaging (around €0.11 per WhatsApp template) and no per-user fees, so you add channels and clients without seat costs. A 14-day free trial includes 100 test messages and needs no credit card. Agencies mark this up into monthly retainers and keep the margin between platform cost and client price.

Which channels can agencies offer clients through SendSeven?

Every channel from one platform: WhatsApp, SMS, email, Instagram, Messenger, Browser Push, Live Chat, and Telegram. WhatsApp carries a 98% open rate for campaigns, Browser Push retargets at 15-20% with no email address and €0 CPM, and email runs on a drag-and-drop builder with click tracking. Each channel becomes a separate billable service.

Is SendSeven GDPR-compliant enough to recommend to clients?

Yes. SendSeven hosts all data in the EU with AI processing in Frankfurt (Vertex AI) and no third-country transfers, and it covers Art. 28 GDPR data processing agreements, a decisive argument for clients with sensitive customer data. Double opt-in works across every channel, with role-based access, encryption at rest, and audit logging. You recommend a tool that protects your reputation.
