The Best Inbound Marketing Software Tools for SaaS - 2023 Edition

By Will Steward on Tue, Feb 28, 2023

Inbound marketing is impossible without the right software.

It doesn't matter whether you're implementing a full-funnel inbound marketing strategy, or just trying to drive more targeted traffic to your SaaS company website. You need a toolkit to be effective.

For the last decade I've implemented and extensively used inbound marketing software for both Cobloom, and the companies we work with.

Our top recommendations power this website, and its marketing.

In today's post I explore why SaaS companies need inbound marketing software, and review the most popular tools available, so you can make informed choices.

Let's get started!

An Introduction to Inbound Marketing Software for SaaS

What is Inbound Marketing?

Marketing strategies can broadly be split into two distinct categories: inbound marketing, and outbound marketing. Inbound marketing is all about attracting people to your website and brand, whereas outbound marketing is focused on pushing your messages out to potential customers.

Core Inbound Marketing Tactics

  • Blogging - regularly writing search optimised blog content, driving traffic to your website from search engines
  • Landing Page Creation & Optimisation - creating landing pages with forms on them, which convert website visitors into leads
  • Email Marketing - sending emails to leads generated with your inbound marketing strategy, to convert them into free trials / demos / sales
  • Marketing Automation & Lead Nurturing - automating marketing processes with software, such as the sending of sequences of emails designed to "nurture" a lead so that they're ready for a free trial / demo / sales conversation
  • Search Engine Optimisation - optimising your website for search engines & using link building strategies to maximise search rankings
  • Lead Generation Content Creation - creating helpful content like eGuides and whitepapers, usually promoted on landing pages to generate leads
  • Webinar & Video Marketing - creating high quality video content to help educate website visitors & leads
  • Surveys / Quizzes - using surveys/quizzes to turn website visitors into leads and collect useful statistics for creating your own reports, etc
  • Social Media Marketing - building a brand and audience on social media, driving regular traffic back to your website
  • Pay Per Click Marketing (PPC) - Paying per click for traffic from search engines or social media websites. For the purposes of this post, we include pay per click marketing as an inbound marketing strategy, but it's borderline.

    We include it because the most effective inbound strategies typically also leverage PPC either to start a campaign, or boost it, and PPC functionality is included in the software we've reviewed.

There are many others, but most SaaS companies with effective inbound marketing strategies will be using the above tactics as the main building blocks of their campaigns.

What Types of Inbound Marketing Software Are Available?

In this resource I focus on Inbound Marketing Platforms, SEO Tools & Content Management Systems (CMS).

  • Inbound Marketing Platforms - software in this category provides a suite of tools designed to allow you to efficiently implement the core tactics outlined above (and more). Top performing SaaS companies select one of these, then use other tools where necessary to fill gaps or supplement requirements.
  • SEO Tools - search engines are central to inbound marketing, and the best performing SaaS companies use advanced SEO tools to ensure their website is optimised appropriately and continually attracting more search traffic.
  • Content Management Systems (CMS) - a content management system is what you use as a platform for your marketing website. It's where your website design and all your content goes. Every SaaS company should be using a content management system of some form, or managing your marketing website becomes impossible.

There are other categories of inbound marketing software out there, but they're increasingly specialist, and aren't of much use until you have the above essential tooling in place.

Quick fact: did you know that digital marketing software spend reached $66.7 billion in 2022? Total spend is expected to reach at least $161.7 billion by 2028, a growth rate of 15.8% per year. Source: IMARC Group

Inbound Marketing Platforms for SaaS Companies

1) HubSpot

HubSpot provides you with all of your inbound marketing tools and data -- connected in one place. You can start using their CRM, email marketing, forms, landing pages, live chat, blog, pay per click ad management and contact management features for free.


Premium versions go further, including omni-channel marketing automation, retargeting, SEO, blogging, social media management, account-based marketing, testing, predictive lead scoring, and advanced analytics covering the entire customer journey.

HubSpot Enterprise offers single sign-on, custom objects, team management tools, multi-touch revenue attribution, custom events, HubDB, and much more, to meet the needs of Scale-ups that have more complex requirements.

HubSpot's platform is designed to help you reach the right people at the moments when they're ready to take the next step in the purchasing journey:


We've used HubSpot for ourselves and our clients since 2013, and have been delighted with the software & support we've received throughout that journey. The platform achieves a difficult balance exceptionally well: providing power & customisability to those who need it, while remaining very easy-to-use.

The free/starter tools are great for very early stage start-ups, while HubSpot Marketing Pro & Hubspot Marketing Enterprise serve scale-ups better than any other platform.

As a small team using the platform in combination with the inbound marketing methodology we've attracted in excess of 25,000 monthly visits to our website, generated many thousands of inbound contacts and booked hundreds of sales meetings.

If you're a Start-up SaaS company (you have an early stage product, but perhaps aren't sure if you have product/market fit and aren't in "scaling mode"), click here to learn more about HubSpot, and get started for free.

If you're a Scale-up SaaS company (you already have an established product, and are focused on scaling up growth), learn more about HubSpot by starting a free 14-day trial of their Professional package.

Quick fact: did you know that HubSpot's co-founder Brian Halligan coined the term "inbound marketing", back in 2005?

2) ActiveCampaign

ActiveCampaign is a Customer Experience Automation platform that helps SaaS companies to engage with potential (and existing) customers. Its Plus package includes email marketing, forms, landing pages, marketing automation, custom events and more. 

segmentationThe Professional package goes further, offering AI-powered predictive sending functionality, split automations, site messages and attribution reporting. There's also an Enterprise package which includes things like single sign-on, custom objects, SLAs and important features established SaaS companies might need.

Unlike HubSpot, its platform doesn't include a free CRM by default, but you can purchase a bundle of ActiveCampaign's Marketing Automation + CRM which starts at just $93 per month. In contrast to some of the platforms featured later in this article, ActiveCampaign's CRM is natively integrated with its Marketing Automation Software to offer a seamless user experience.


As of the writing of this post, ActiveCampaign doesn't have a blog, Content Management System, or SEO tools. This means that if you choose to use ActiveCampaign you'll need to have your marketing website hosted on an external CMS, which adds some technical complexity.

While narrower in scope, ActiveCampaign is an appealing solution to SaaS companies where cost is the central concern (so especially early-stage, bootstrapped Startups and SaaS teams with only 1 or 2 marketing employees), and HubSpot's free tools just don't provide the depth of functionality you need.

Where ActiveCampaign really shines is for SaaS companies which have a low touch or no touch sales process. It started out as a B2C workflow platform, and has a lot of functionality built into even its lower tier packages which is very useful for SaaS companies that wish to completely automate their sales process, rather than use a sales team.

Both ActiveCampaign and HubSpot have high rates of Highly Satisfied customers: in 2022 a survey was commissioned (by HubSpot) of both company's paying customers. 958 HubSpot customers were surveyed, and 498 ActiveCampaign customers. According to the survey, 37% of HubSpot customers were "Highly Satisfied" (scoring 9-10 out of 10 on the customer satisfaction survey), in comparison to 33% of ActiveCampaign customers.

To summarise, and help you answer whether you should choose HubSpot or ActiveCampaign as your central Platform:

  • Choose HubSpot if you want a comprehensive all-in-one solution which will scale with your SaaS. HubSpot is usually the best solution for funded start-ups, scale-ups and established SaaS companies which have a high touch sales process.
  • Choose ActiveCampaign if you're happy to integrate more tools together to deliver and report on your Inbound Marketing Campaigns, and your main software requirement is Email Marketing and Marketing Automation. ActiveCampaign serves as a great "second-best" when budgets are stretched, and works well for bootstrapped start-ups.

    It's also a compelling option for SaaS companies which have a very low touch or no touch sales process, and therefore need custom event-triggered emails, something available in most ActiveCampaign packages, but only HubSpot Enterprise.

3) Adobe Marketo Engage

Marketo is a tool which primarily offers email marketing, marketing automation, landing pages, forms, A/B testing, account-based marketing, reporting and SEO. They also provide a chatbot which can be used to engage visitors while they're using your website. They do not have a free version of their product currently.

A major reason we don't rank Marketo as highly as HubSpot is that their product offering is narrower, which means that you need to combine it with other tools to do everything they do. It doesn't really enable you to implement effective inbound marketing strategies from the start, "out of the box", like HubSpot, requiring more setup work. For a narrower solution, it's also much more expensive than ActiveCampaign.

Marketo doesn't include a CRM, which means you'll need to use and integrate another CRM if you don't already have one in order to use it properly.

Note: HubSpot and ActiveCampaign also support integrations with external CRM systems, if you don't want to migrate from what you're currently using. 

For SaaS companies serious about growth, we don't think Marketo compares to HubSpot as an overall Inbound Marketing Platform. Marketo simply hasn't been designed for the purpose from the ground up like HubSpot was.

Still, Marketo remains a popular alternative Marketing Automation platform, and scale-ups in particular will get value from some of its more advanced capabilities. It's one of HubSpot's closer competitors when it comes to an Inbound Marketing Platform's required features.

As a platform we don't believe it offers suitable options for early stage start-ups, but scale-ups can request their free Interactive Tour.

4) Pardot (Salesforce Marketing Cloud Account Engagement)

Pardot is a tool which primarily offers email marketing, marketing automation, lead nurturing, landing pages, forms, A/B testing & reporting. It was acquired in 2007 to help Salesforce build out their portfolio of products, and enter the marketing automation space.


It's one of the most popular marketing automation platforms in no small part because it's owned by Salesforce, who promote it to their existing base of CRM customers.

Generally speaking, Pardot tends to be more difficult to use than the other software we've explored. Salesforce have grown their product offering primarily by acquiring other companies, and that means all their software requires integrations which can get quite complex.

Another flaw is that due to how Pardot's landing page integration works, you often have to host landing pages on a subdomain or third party website separate from your main marketing website, which adds complexity to the user experience/reporting, and negatively impacts SEO.

Like Marketo, you'll need to integrate with a separate CRM, as a CRM isn't included with Pardot. Salesforce (naturally) recommend Salesforce, but last time we checked the integration is still manual rather than native.

Regardless of those downsides, Pardot is still used by a number of SaaS companies. At the price point we're unsure why an informed buyer would choose Pardot over HubSpot if they wanted to do inbound marketing, however.

You can request a free demo of Pardot via the button below. It's only really suitable for scale-ups, and starts from $1,250 per month.

SEO Tools for SaaS Companies

1) SEMRush

Semrush is what we'd describe as the ultimate SEO tool. It's an all-in-one tool suite you can use to increase your online visibility and discover actionable marketing insights.

In our experience, it's not enough to "just" have an Inbound Marketing Platform for your SEO: you also need a tool to help with research, so you know what keywords you should be targeting, how your search engine rankings are evolving and how to improve upon your linkbuilding strategy. Semrush is the software you want for this.


Within Semrush there are tools which help you with: keyword research, on-site SEO, competitor SEO analysis, local SEO, content strategy, search rank tracking, link building, content performance analytics, and more. 

You can dive into individual keywords, like "inbound marketing" for example, and quickly see how traffic is spread globally, how difficult it would be to rank for the keyword, what the Google Adwords CPC would be and common questions people ask about "inbound marketing" as well as longer tail "inbound marketing" related keywords you might want to pursue instead (or in addition):


Do a keyword gap analysis between your website, and your competitors, helping you to surface search phrases your competitors are generating traffic for, but you aren't:


Build and implement linkbuilding campaigns. Semrush can analyse all your competitors websites and your target keywords in order to surface outreach opportunities you could use to build links back to your own content. For Cobloom, the software identified thousands of such opportunities:


And so much more.

The best way to learn about Semrush is with their free trial. In minutes you can be identifying new keywords to optimise your content strategy around, finding link opportunities and comparing your search performance with competitors.

A downside to Semrush is that their free trial requires you to enter a credit card to start, to prevent misuse. They don't bill you anything when you start the trial, but if you don't find the software as valuable as we do, you'll want to set a reminder to cancel your subscription when the 7 days are up to avoid being billed for your first month.

We recommend it as a must-have tool for SaaS companies which are serious about SEO. There are three tiers of packages, but we find that most SaaS companies have what they need within the cheapest Pro Package ($119.95/mo for 1 user).

There are loads more useful add-ons, but the need for these is much more case-by-case, and you can learn about this premium functionality on the Semrush website.

2) Ahrefs

Ahrefs is a close second to Semrush. It started out as a tool primarily for analysing links (hence the name!) but has evolved over the years to compete more directly with Semrush's research tools.

While Ahrefs in some cases has a slightly better designed user interface, Semrush provides you with a lot more data across both SEO & PPC, making it a better choice for keyword research purposes.


When it comes to linkbuilding & backlink analysis, some quick testing by us suggested that both Semrush and Ahrefs detect a similar number of backlinks, meaning that overall there isn't that much in it.


For established websites, other third party research has found that Semrush tends to find a few more links than Ahrefs, typically in the order of ~1% more referring domains. 

Finally, when it comes to comparing Ahrefs technical SEO site audit functionality with Semrush, Ahrefs has a tendency to repeatedly flag up issues which aren't really issues (e.g. setting some pages as noindex, something there are many good reasons for doing!).

Semrush by comparison provides you with loads of great, actionable site audit advice you can use, while making it easy to dismiss or hide recommendations which aren't relevant to you.

In terms of cost, Ahrefs starts at $99/mo, but many SaaS companies may find they need the Standard ($199/mo) or Advanced ($399/mo) packages to get the functionality they need.

Ahrefs unfortunately doesn't offer a free trial of its service anymore, but you can create a free account which grants you access to a very limited set of its features.

Content Management Software for SaaS Companies

1) HubSpot

HubSpot's CMS makes building scalable SaaS marketing websites easy. You can use it to create and personalise website pages for every visitor - optimised to convert across all devices. Flexibility within the CMS and intuitive drag & drop page builders mean you can rely on developers as much or as little as you'd like.


This website (cobloom.com) & blog is built entirely on the HubSpot CMS. Sometimes when I'm editing content I use the drag & drop tools, others I edit source code directly. I've had colleagues who know nothing about website development edit page templates, designs and content without issue using only drag & drop.


Like HubSpot's other products, you can start using the website pages, blog, drag-and-drop editor, basic SEO tools, managed cloud hosting & website traffic analytics for free.

Premium versions of the CMS enable you to deploy as many websites/pages/blogs as you want, receive automated advanced SEO recommendations, create dynamic content, build contact attribution reports, perform A/B testing and do adaptive testing.


Digging a bit further into the dynamic content functionality, you can effectively personalise website content the same way you can personalise emails with HubSpot's email marketing software. Check out the screenshot below, where I'm adding a contact's "Company Industry" to a webpage:


Like with email, you can set a "default" that people who aren't contacts in your database see when they visit the page too. So for a "Company Industry" example a default might be "your industry", where a known contact would instead see "manufacturing industry", or "software industry". This personalisation helps to boost engagement and conversions.

I could go on and on, but you really need to see the software to fully appreciate it.

It's the only CMS for SaaS companies that's both powerful and easy-to-use.

2) Wordpress

It's impossible to talk about CMS' without also reviewing the world's most popular free CMS: Wordpress.

Before re-branding as Cobloom in 2016, our company was known as Iconsive, and we initially hosted the company's marketing website on Wordpress. I've heavily used Wordpress myself, and spent many years building and optimising Wordpress websites.

The biggest thing to highlight is that Wordpress isn't a CMS optimised for inbound marketing: it's a generic CMS designed to be customised with themes & plugins. In order to effectively implement inbound marketing strategies with Wordpress your marketing team will need to regularly have someone available who knows how to code, and use plugins for SEO functionality, analytics, forms, etc.


It's worth noting here that if you were to install 24 of the most popular Wordpress plugins, you'd be paying between $287 and $1,338 per month for them. Many of the best plugins aren't free.

Also, unlike HubSpot, Wordpress is a software package that has to be installed & configured on either your servers, or the servers of a third-party hosting provider. This means that Wordpress isn't totally free even without plugins. Hosting costs can add up, especially if your website drives significant amounts of traffic or you plan to do lots of webinars/video marketing. HubSpot by comparison takes care of all of that for you, so you don't have to worry.


Wordpress none-the-less remains a popular CMS, and many SaaS marketing websites continue to use it in spite of the associated complexity. You can learn more about Wordpress on their website, here.

If you don't want to host your own Wordpress instance, you can get managed Wordpress hosting here.

It's worth noting that if you have a strong reason for wanting to use Wordpress over the HubSpot CMS, that HubSpot has its own Wordpress plugin and integrates exceptionally well. Many SaaS companies achieve results hosting their website on Wordpress, while using HubSpot as their Inbound Marketing Platform.

To conclude, if you were to ask me the question, "what inbound marketing software combination will maximise the performance of our SaaS marketing strategy?" I'd answer as follows:

  • Use HubSpot as your Inbound Marketing Platform. Its functionality is second-to-none, and you won't regret using it at the centre of your marketing. We've recommended HubSpot to many SaaS companies who have successfully used HubSpot Pro & HubSpot Enterprise for years without looking back.

    The main exception to this is if you have a low touch or no touch sales process, also take a look at ActiveCampaign. The software was initially designed for companies with automated sales processes, and contains functionality in its lower tiers which will be valuable to you.

    Start your free 14-day trial of ActiveCampaign
  • Use Semrush's tools to really take your SEO to the next level. If you're serious about achieving inbound marketing success, SEO is critical. While HubSpot contains a number of great SEO tools (in particular for on-site optimisation); you also need something more for market research, keyword research, competitor analysis and linkbuilding analysis. That's where Semrush comes in.

    Semrush is essential if you're using ActiveCampaign, as the platform does not offer built-in on-site SEO optimisation features.

    Start your free 7-day trial of Semrush
  • Use HubSpot's CMS as your content management system. It's packed full of functionality which in our experience makes it a much better option than generic CMS software like Wordpress. If you use Hubspot's Inbound Marketing Platform as well, the CMS has a seamless integration with it.
