The right platform helps you:
Below, we’ll walk through nine well-known marketing automation platforms, what they’re best at, and a few practical considerations for choosing between them.
Before you look at individual tools, get clear on:
With that in mind, here’s a breakdown of nine platforms that consistently show up in marketing teams’ shortlists.
Customer.io is built for companies that want to trigger communication directly from user behaviour—especially SaaS and product-led growth businesses.
Where it shines
Consider if
You want fine-grained control over behavioural triggers and are comfortable working with events, webhooks, or basic dev resources to get the most from it.
HubSpot is often the default choice for teams that want marketing automation and an easy-to-use CRM in one platform.
Where it shines
Consider if
You want to centralize your marketing and sales data in one place, are invested in inbound marketing, and don’t mind paying more as you scale into advanced features and larger contact volumes.
Marketo (now Adobe Marketo Engage) is a heavyweight platform used widely in enterprise B2B for sophisticated lead management and account-based marketing.
Where it shines
Consider if
You have a mature marketing operations function, a long B2B sales cycle, and the team capacity to properly implement and maintain a powerful but complex platform.
Previously known simply as Pardot, Salesforce’s Account Engagement product is designed for B2B teams already deep in the Salesforce ecosystem.
Where it shines
Consider if
Your business already runs heavily on Salesforce, you want native alignment between marketing and sales data, and you can invest in implementation and admin support.
Mailchimp is often the first serious email and automation tool many small businesses adopt—and it has grown beyond “just newsletters.”
Where it shines
Consider if
You’re primarily doing email-led campaigns, don’t need very complex logic, and value speed and simplicity over deep customization.
Constant Contact has long been a go-to for small organisations that want consistent outbound communication without a lot of complexity.
Where it shines
Consider if
You want something more powerful than a basic newsletter tool, but you don’t need all the bells and whistles of a full marketing automation platform.
Keap is designed for small businesses that want CRM and marketing/sales automation in one tool, without going full enterprise.
Where it shines
Consider if
You’re a growing small business or solopreneur who wants marketing and sales processes in a single, moderately opinionated platform.
DialogTech, now part of Invoca, focuses on the phone call side of marketing automation—where many high-value conversions still happen.
Where it shines
Consider if
Phone calls are a key part of your funnel, and you want to close the attribution gap between digital campaigns and conversations happening over the phone.
iContact offers email marketing and light automation for teams that want to keep things simple but still professional.
Where it shines
Consider if
You want something easy to manage that still gives you more structure and automation than a bare-bones newsletter tool.
You don’t need the “biggest” platform, you need the right-sized one for your:
As you shortlist tools:
Map your must-have workflows first.
Sketch out how leads should move from first touch to sales-ready. Then evaluate which platforms can support those journeys with the least friction.
Start with one or two high-impact automations.
For example, a simple “demo request → nurture series → sales handoff” flow, or an onboarding series tied to product usage milestones.
Connect it to your CRM and analytics early.
Clean data is the difference between “pretty emails” and “provable revenue impact.”
Pilot, learn, then scale.
Run a limited pilot with real campaigns before committing long-term. Look at both performance and day-to-day usability for your team.
With a thoughtful approach, any of the platforms above can help you reclaim time, improve lead quality, and build a more predictable pipeline, without burning out your team in the process.
A marketing automation platform helps you run repeatable marketing tasks automatically, such as email sequences, lead nurturing, segmentation, follow-ups, scoring, and reporting. It connects your data with your messaging so campaigns run consistently without manual effort.
Automation solves the “too much to do, not enough time” problem. It reduces repetitive work, improves follow-up speed, keeps leads warm over longer buying cycles, and creates more consistent customer communication across email, forms, ads, and CRM activity.
Email tools focus on sending newsletters and campaigns. Automation platforms add behavioural triggers, multi-step workflows, segmentation, lead scoring, and CRM integration, so messages change based on what someone does, not just who they are.
Choose based on your customer journey and the workflows you actually need. Prioritise tools that integrate with your CRM and website, support the channels you use (email, SMS, ads, landing pages), and make reporting easy enough that your team will use it weekly.
Not always, but you’ll get far more value if your automation tool can connect to a CRM or includes CRM functionality. Without a CRM, automation can still run campaigns, but tracking pipeline impact and handover to sales becomes harder.
Start with the highest-impact, lowest-complexity flows: a welcome series, lead capture follow-ups, nurture sequences for key services, re-engagement for inactive contacts, and simple internal notifications so enquiries never get missed.
The biggest differentiators are: workflow flexibility, segmentation and triggers, CRM and website integrations, deliverability tools, reporting and attribution, ease of building forms and landing pages, and how well the platform supports your team’s day-to-day process.
Most teams can implement a lean automation foundation in a few weeks if the data is clean and the journey is clear. The biggest time sinks are usually contact data, tagging, integrations, and agreeing on what “qualified” actually means.
They fail when platforms are chosen for features instead of workflows, when data is messy, when no one owns the system, or when reporting isn’t used to improve campaigns. A smaller set of automations, built well and reviewed regularly, beats a complex setup that no one trusts.
Yes. Small teams often benefit the most because automation replaces manual follow-up and keeps marketing consistent. A simple setup with lead capture, nurture, and reactivation can drive meaningful pipeline without adding headcount.
Track outcomes, not just opens and clicks. Useful metrics include lead-to-meeting conversion, pipeline created, time-to-first-response, conversion by segment, reactivation rate, and revenue influenced by lifecycle campaigns.
Yes, but plan it carefully. The key is mapping your lists, tags, fields, automations, and forms before moving anything. Many teams also use migration as a chance to simplify workflows and clean up data so the new system performs better from day one.
