In this list, you’ll find 30+ growth marketing tools, extensions and plug-ins that I use in 2021 or which I would advise to my clients. These tools will give you new opportunities in your sales and marketing and will make your work a lot easier!
There are hundreds of growth marketing tools in the world, but these are the most important growth tools that you should know. Let me know if you miss something!
Growth Hacking Tools
Expandi is the #1 growth hacking tool for B2B marketers who work a lot with LinkedIn. Expandi gives you the opportunity to automate your LinkedIn marketing. You can automatically view profiles, send people invites or send messages based on the characteristics of your ideal customer.
Zapier is a must-have for every growth marketer. Zapier is a tool that connects 1,000+ marketing tools to each other to create powerful automations. For example, you can automatically record all your Typeform respondents in your Mailchimp account, or you can, like me, place all your favorite Pocket articles directly on your WordPress website via Airtable. Marketing Automation is one the most important growth hacker skills and can make you so much more productive, and that’s why I had to mention Zapier in our list of tools for growth hackers.
CrystalKnows helps you to understand others better. Based on a person’s social profile, Crystal gives you a personality profile and tips on how to best interact with this person. Is this person more interested in numbers or in emotions? Does this person prefer to communicate in a businesslike way or rather a more personal tone in your e-mails? Very useful and largely free tool!
GrowthBar is an SEO Chrome Extension, that makes your SEO-life a lot easier! GrowthBar automatically shows you (with every search in Google):
- The keyword difficulty of your search term
- Similar keywords, including volumes and CPC
- Most important SEO statistics for each result (e.g. how much traffic a page gets, how valuable that traffic is, and that result’s Domain Authority)
- And even the Facebook Ads from that competitor
I like GrowthBar as a growth marketing tool since it’s made by two real growth hacking experts (Mark & Hailey from GrowthMarketingPro), which really ensures that it is suited for my needs as a growth hacker.
Other alternatives are Ahrefs SEO Toolbar and Moz’s MozBar. I prefer GrowthBar for its ease of use. The MozBar was always your best option, but nowadays it isn’t that easy to use. Ahrefs’ SEO Toolbar is your best option if you prefer Firefox as a browser instead of Google Chrome.
Chatbots were the hottest trend in 2018 and the tool Landbot gives you the possibility to quickly and easily create your own chatbot. Fantastic to show to your boss and colleagues, and it is very effective as a FAQ bot or instead of a boring contactform.
Hotjar is a heatmapping tool. Hotjar gives you great insights into the behavior of your users through heatmaps and recordings of your website visitors in action. I always use Hotjar myself, because the free package is very complete and the most used tool in the industry (that’s a benefit since it can be integrated with many other growth hacking tools).
I must admit that there are a lot of other tools like Hotjar and possibly with different / better functionalities, so take a look at for yourself at these competitors: CrazyEgg, ClickTale or Lucky Orange.
Airtable is a combination of Google Spreadsheet / Excel and a database. It is difficult to understand, but for anyone who works a lot with spreadsheets or data (like most growth hackers do), this tool will come as a great enrichment. For example, you can create smart CRMs or Kanban boards if you integrate it with Zapier. Definitely take a look!
“Push notifications” is one of the latest channels in marketing since it became possible to send notifications without people having to download your app. If you install PushCrew on your website, you can send notifications to site-visitors about new offers, new blog posts or keep people informed about their order. Even if they’re not in their browser.
Sometimes you know exactly who you want to contact, but you don’t have this persons e-mail address. Rest assured, because there are countless tools on the internet that you can use to retrieve someone’s e-mail. Hunter.io, formerly “EmailHunter”, is the oldest option, but you can also try Prospect.io, Voila Norbert, FindThatLead or Skrapp.io.
Every Growth Hacker must be able to build landing pages! You can do that within your own website, or -if your development-team prefers not to give everyone access- you can use Instapage (or one of the many alternatives, such as Unbounce or Leadpages). I do not really have a personal favorite in this category, but I think a landing page tool should not be missing here in this list of growth tools.
(Small update: Due to an update in the Instapage pricing, where prices went up a lot and its cheapest plan now costs $99/month, I would advise picking one of its alternatives.)
Everyone knows the Booking.com-warnings, like “Only 2 rooms left in this hotel”, “76 others are looking at this hotel right now” and “Someone from Amsterdam has just booked this room”. Very annoying, but it does works to be honest. We call that the scarcity-principle or “Fear Of Missing Out” and that is exactly what this eponymous company does for you: notifications and fomo-statements.
I leave it to you whether you want to use it or not, but FOMO is “GDPR Approved” if you were wondering.
LeadFeeder shows you which companies have visited your website which gives you the possibility to address these non-converting companies or better optimize your site for them. I can really recommend this as a growth hacking tool for B2B companies who are very sales-dependent.
Clearbit enriches or ‘
An alternative to Clearbit is the Dutch startup Klue, which I as a dutchman can really recommend.
Of course you have to send a lot of e-mails as an online marketer or growth hacker, so you will need an e-mail marketing tool. Mailjet is my personal favorite for that, because they collaborate so well with Zapier and offer the possibility for simple, personal e-mails as well as well-designed newsletters.
Looking at alternatives, I’ve tried them all, such as Sendgrid, AWeber, Customer.io, Mailshake and of course Mailchimp. If my clients budget was large enough, I often preferred to choose Drip or ActiveCampaign due to their multichannel capabilities.
In everything you do within marketing, you’ll have to write copy: copy for advertisements, copy for landing pages, copy for blogs, copy for social media posts or copy for emails. In my opinion, copywriting one of the most undervalued skills of a growth hacker.
That’s why I use Hemingway and Grammarly for social media copy. These are two chrome extensions that check all your texts in real-time for grammatical errors, language errors or spelling errors. Unfortunately, they only work in English, but nevertheless useful for all non-native writers in English.
Sometimes you’ve got some chores that you can’t automate with a growth hacking tool, but luckily you have Fiverr! It is not really a tool, but certainly a nice resource for any (growth) marketer.
On this website you’ll find freelancers from all over the world for any task you need to get done. Think of filling in long spreadsheets, transferring an illustration to Sketch or animating your company logo. Everything is possible and it is often very cheap, because freelancers in other countries never need as much as freelancers in the western world. You can also check out UpWork as an alternative.
Ghostery is actually meant to block tools that try to track your behavior on the web, but I (and many growth hackers with me) use Ghostery to see which tools a website uses. It is very interesting to look through this chrome extension and to see, for example, which tools your competitor or upcoming client already uses!
As a Growth Hacker (or as an Online Marketer), you will often have to design something, such as an image for a social media post or a visual for your website. I use Canva for that! This is the tool that I use most of all, because it makes it easy to create or create visuals.
From now on you never have to bother your designer for small tasks or when you are in a hurry. This tool should not be missing in your arsenal of growth hacking tools.
25. Viral Loops
The most famous growth hacking examples consist of ‘referral programs’, whereby your current customers will act as ambassadors and bring in their friends as new users. Think for example of the growth hacks of PayPal and Dropbox. Viral Loops gives you everything you need to set up your referral program. You could also take a look at Referral Candy or Maître.
‘Scraping’ is one of the growth hacking skills that most people get most excited about. Import.io is one of the first webscraping tools and makes it possible to convert any data from the web into spreadsheets. Very interesting so if you have to do large-scale work.
As an easier alternative to Import.io, you could have a look at the chrome extension ‘Data Miner‘.
As I often say in this list, it is important to save yourself time. That is why Calendly is a commonly used tool among growth hackers and startup-entrepreneurs. Calendly gives your potential customers the opportunity to immediately schedule an appointment in your agenda. This way you don’t have to email back and forth to plan an appointment and your sales calls automatically appear in your diary.
Google Tag Manager gives growth hackers and online marketers the capabilities of a developer without bothering the developer. Once you have installed GTM, you can use it to, for example, install other tools in the code of your website or you can track user interactions and automatically forward this data to Google Analytics or Mixpanel.
MixMax is a great friend for many sales people and growth hackers. MixMax is an extension of your Gmail and gives you insight into your sent e-mails: Has the recipient already opened it? Has he / she already viewed the attachment or the link? Has the mail already been forwarded to the supervisor? Very useful!
In addition, MixMax also gives you the opportunity to make your e-mails a lot fancier, to schedule them to send later and to use templates.
I would advise using a user onboarding tool like
An alternative to Userlane might be Appcues, but I don’t have any experience with them.
FollowLiker gives you the ability to automatically follow, unfollow, post messages or like targeted posts on Twitter, Instagram or Pinterest. Especially suitable if you want to grow one of those channels. Sadly, there is no such alternative for Facebook. For LinkedIn, I would recommend Expandi.io or DuxSoup, which I’ve also mentioned in this list.
