If your marketing delivery strategy still starts and ends with email and SMS, you are leaving enormous value on the table. The channel landscape has exploded, and the winners are meeting customers where they actually spend time.

Email is not dead — but it is no longer the center of the universe. 2026 marketing leaders are orchestrating campaigns across a growing list of channels, and the economics are compelling.

Why the Channel Expansion Matters

Attention fragmentation is real. Your customers spend time across dozens of platforms. Email gets seen when it gets seen. But push notifications, in-app messages, and social DMs arrive in real-time with higher engagement rates.

Channel-specific economics. Email has become expensive to send profitably. Deliverability costs, list hygiene requirements, and regulatory compliance have all increased. Meanwhile, WhatsApp messages in certain markets cost a fraction of SMS with higher open rates.

Customer preference diversity. Different customers prefer different channels. Some never check email. Others have SMS notifications disabled. The only way to reach everyone is to reach them everywhere.

The New Channel Mix

Push Notifications (Web and Mobile)

Web push has matured significantly. Permission rates of 3-7% for engaged sites are common. Open rates of 4-8% dwarf email. The key: do not abuse it. Push is a privilege, not a broadcast channel.

WhatsApp and Messaging Apps

WhatsApp for Business is now a serious marketing channel. Broadcast lists, automated conversations, and transactional messages all work. In markets like Latin America, Europe, and growing in the US, WhatsApp is the primary communication channel.

In-App and In-Product Messaging

If you have a product, you have a channel. SaaS companies are seeing massive returns from contextual in-app messages — triggered based on user behavior, feature usage, and journey stage.

Social Media Direct Messaging

Instagram DM, LinkedIn messaging, and even Twitter/X DMs are viable for B2B and B2C. The key is personalization — automated but not robotic.

Voice and Audio

Audio is an emerging channel. Podcast ads are maturing. Some brands are experimenting with voice-based marketing — Alexa skills, voice search optimization, and audio newsletters.

Newsletters and Content Platforms

Substack, Beehiiv, and similar platforms have created a new content distribution channel that is permission-based and highly engaged. Newsletter marketing is effectively its own channel now.

Building a Channel Strategy

The goal is not to be everywhere. It is to be where your customers are with the right message at the right time.

Step 1: Map your customer journey. Identify every touchpoint. Where do they discover you? Where do they evaluate? Where do they buy? Where do they renew?

Step 2: Assign channels to journey stages. Awareness might be Instagram. Consideration might be email. Purchase might be SMS. Retention might be push.

Step 3: Build the orchestration layer. You need a system that coordinates messages across channels. This is where a CDP or marketing orchestration platform earns its keep.

Step 4: Test and optimize per channel. What works in email will not work in push. Each channel has its own psychology, timing, and format preferences.

The Bottom Line

The future of marketing delivery is omnichannel — but not the dumb kind where you blast the same message everywhere. The sophisticated version is channel-specific, context-aware, and orchestrated to deliver the right message through the right channel at the right moment.

Email and SMS are still important. They are just no longer the only game in town.
