HubSpot vs Mailchimp vs Klaviyo; Which Platform Is Right for Your Business?

Choosing the right marketing platform can have a significant impact on how your business attracts, nurtures and retains customers.

With so many options available, it's easy to feel overwhelmed. Three of the most popular platforms are HubSpot, Mailchimp and Klaviyo, but they aren't designed for exactly the same purpose.

While each platform offers email marketing, they excel in different areas and are suited to different types of businesses.

So, which one is right for you?

Why choosing the right platform matters

Many businesses choose a platform based purely on price or popularity.

Unfortunately, this often leads to outgrowing the software within a year or paying for features they never use.

The right platform should support your business as it grows, automate repetitive tasks and help you build stronger customer relationships.

Before comparing features, ask yourself:

• What are your business goals?

• Do you sell products or services?

• How large is your customer database?

• Do you need a CRM?

• Do you want advanced automation?

• Will multiple team members use the platform?

Answering these questions first makes choosing the right platform much easier.

What is HubSpot?

HubSpot is an all in one CRM and marketing platform designed to help businesses manage their entire customer journey.

Rather than focusing only on email marketing, HubSpot brings together:

• CRM

• Marketing automation

• Email marketing

• Landing pages

• Forms

• Sales pipelines

• Customer service tools

• Reporting dashboards

• Content management

• Lead scoring

Everything sits within one connected system, making it particularly valuable for businesses that want sales and marketing working together.

HubSpot is ideal for:

• B2B businesses

• Professional service companies

• Growing SMEs

• Businesses with sales teams

• Companies generating leads rather than online purchases

Advantages

• Powerful CRM included

• Excellent automation

• Detailed reporting

• Sales and marketing integration

• Scales as your business grows

Things to consider

HubSpot offers extensive functionality, but because of this it takes more time to set up properly.

Businesses usually benefit from an implementation strategy rather than simply activating the software and hoping for the best.

What is Mailchimp?

Mailchimp began as an email marketing platform and remains one of the easiest systems for beginners.

It's popular with small businesses because it offers a straightforward way to create newsletters and basic automated emails.

Over recent years it has added CRM features, landing pages and automation, although these remain less comprehensive than HubSpot.

Mailchimp is ideal for:

• Small businesses

• Start ups

• Local organisations

• Charities

• Businesses sending regular newsletters

Advantages

• Easy to use

• Quick to set up

• Good email templates

• Affordable for smaller databases

• Suitable for straightforward campaigns

Things to consider

As businesses grow, many find Mailchimp's automation and CRM capabilities become restrictive.

For businesses with more complex customer journeys, another platform may offer greater flexibility.

What is Klaviyo?

Klaviyo was built specifically for ecommerce businesses.

Rather than acting as a general CRM, it focuses on helping online retailers increase revenue through personalised email and SMS marketing.

It integrates seamlessly with platforms including Shopify and WooCommerce, allowing businesses to create highly targeted campaigns based on customer behaviour.

Klaviyo is ideal for:

• Ecommerce brands

• Shopify stores

• WooCommerce stores

• Online retailers

• Product based businesses

Advantages

• Excellent ecommerce integrations

• Advanced customer segmentation

• Powerful automation

• Revenue focused reporting

• Behaviour based marketing

Things to consider

If your business doesn't sell products online, Klaviyo's specialist ecommerce features may be unnecessary.

Which platform is best for ecommerce?

If you run an online store, Klaviyo is often the strongest choice.

Its automation can trigger emails based on:

• Products viewed

• Abandoned baskets

• Previous purchases

• Customer value

• Buying frequency

• Product categories

These behavioural triggers help increase repeat purchases without increasing advertising spend.

Which platform is best for service businesses?

Professional service businesses often benefit most from HubSpot.

Instead of focusing purely on purchases, HubSpot helps businesses manage:

• Leads

• Sales conversations

• Quotes

• Meetings

• Follow up emails

• Customer relationships

It provides much greater visibility across the entire sales process.

Which platform is best for small businesses?

If you're just starting out and want a simple newsletter platform, Mailchimp remains a solid option.

However, it's worth thinking ahead.

Switching platforms later can be time consuming, so choosing software that supports future growth may save considerable effort.

Common mistakes businesses make

One of the biggest mistakes is choosing software because someone else recommends it.

Every business is different.

Another common mistake is paying for advanced software without having a strategy.

Technology alone doesn't improve marketing.

Success comes from understanding your customers, creating valuable content and building effective customer journeys.

The software simply makes those processes easier.

Can you move between platforms?

Yes.

Many businesses begin with Mailchimp before moving to HubSpot or Klaviyo as they grow.

Migration usually includes:

• Exporting contacts

• Moving email templates

• Rebuilding automations

• Importing customer data

• Testing integrations

Planning the migration carefully helps avoid disruption.
