The State of Marketing Automation in 2021

Marketing automation entered 2021 carrying momentum from a strange year: 2020 had pushed enormous volumes of commerce online, and businesses that had automated even the basics going into that shift came out ahead of those still sending everything manually. The result was a market moving faster than usual, with a few clear patterns defining where it stood.

E-commerce-native platforms pulled ahead of general-purpose tools

Platforms built specifically around online retail, with deep integrations into store data like purchase history, browsing behavior and product catalogs, grew faster in 2021 than more generalist email tools. For a direct-to-consumer brand, automation that could trigger off “viewed this product three times but didn’t buy” or “bought this, and typically reorders in six weeks” was simply more useful than automation built around generic list segments. This is part of why platforms built around Shopify’s ecosystem saw such steep adoption curves that year.

No-code, visual workflow builders became table stakes

Automation that required a developer to configure was a real barrier for small and mid-sized businesses. Through 2021, the platforms winning market share converged on the same interface pattern: a visual, drag-and-drop canvas where a marketer could build a multi-step journey (wait, condition, send, wait, condition) without writing code. This mattered because it moved automation ownership from IT teams to the marketers running campaigns.

SMS got folded into the same automation platforms as email

Rather than businesses adopting a separate SMS tool, the bigger automation platforms spent 2021 building native SMS support directly into their existing workflow builders. That meant a single abandoned-cart flow could branch into email for some subscribers and SMS for others based on opt-in status and urgency, managed from one interface instead of two disconnected ones.

The mid-market started asking for what enterprise had

Customer data platforms, tools that unify behavioral, transactional and demographic data into a single customer profile, had mostly been an enterprise category. In 2021, simplified versions aimed at mid-market and smaller businesses started appearing, driven by demand from marketers who wanted the CRM, the email tool and the ad platforms all working from the same picture of a customer instead of three disconnected ones.

Budget scrutiny caught up with adoption

Not every trend was expansion. As automation spend grew, finance teams increasingly asked marketing to show which flows were producing revenue, not just which ones were technically running. Businesses that had automated a dozen workflows without tracking their individual performance found themselves having to retroactively build that reporting, or cut flows they couldn’t justify keeping.

Where this left the market by year end

By the end of 2021, marketing automation had stopped being a differentiator on its own; enough businesses had adopted some form of it that simply having automated flows wasn’t a competitive edge. The edge had shifted to how well those flows used real customer data, how tightly email and SMS worked together and whether a team could prove which automations were worth the platform fees. That shift, from “are you automated” to “is your automation any good,” set the terms for how the category kept evolving after 2021.
