Discover email platforms that respond to customer actions with automated, personalised messages, from abandoned cart recovery to birthday wishes and onboarding.
Remember when email marketing meant blasting the same newsletter to everyone and hoping for the best?
Those days are over.
Today’s smart email platforms know when someone abandons their shopping cart, celebrates a birthday, or hasn’t opened an email in months – and they automatically respond with the perfect message. The best email marketing doesn’t feel like marketing at all – it feels like the right message at exactly the right moment. These platforms watch what your customers do (like browsing your website, opening emails, or making purchases) and automatically send relevant, timely messages.
Whether you’re a small business owner or managing campaigns for a large company, here are 11 platforms that can turn customer actions into personalised email experiences for you.
Mailchimp
Mailchimp is a popular email marketing tool that helps businesses send the right emails to the right people at the right time. It watches what customers do – like what they buy, which emails they open, or what pages they visit on your website – and uses this information to send personalized messages.
What it can do: Mailchimp can automatically sort your customers into groups based on their behavior, like frequent buyers or people who haven’t opened emails in a while. It can then send automatic emails triggered by specific actions – like when someone signs up for your newsletter, leaves items in their shopping cart, or has a birthday coming up. You can see all of a customer’s activity in one place to better understand what they want.
Who should use it: This works great for small and medium-sized businesses, online stores, and marketers who want a powerful but easy-to-use email tool. It’s perfect if you want to send targeted emails based on customer behavior without needing to be a tech expert, but it’s still flexible enough for more advanced users.
ActiveCampaign
ActiveCampaign is a powerful email marketing and customer management tool that’s great at creating smart, automated email campaigns based on what your customers actually do.
What it can do: ActiveCampaign can automatically start email sequences when customers take specific actions – like opening an email, clicking a link, abandoning their shopping cart, visiting certain pages on your website, or when a sales deal changes status. You can set up over 20 different triggers like these.
The platform has an easy-to-use visual builder where you can create email flows with “if this, then that” logic, delays between emails, customer tags, and updates to customer records. It also uses AI to figure out the best times to send emails, track what people do on your website, test different email versions, and personalize content for each person.
Who should use it: This works best for small to medium businesses and marketing teams who want sophisticated automated email campaigns combined with customer management tools. It’s perfect if you want to create complex email journeys based on customer behavior – like nurturing new leads, winning back customers who abandoned their carts, or re-engaging inactive subscribers – while keeping your marketing and sales teams on the same page.
HubSpot Marketing Hub
HubSpot Marketing Hub is an all-in-one marketing tool that works closely with customer management features to send smart, automated emails based on what customers do.

The basic version lets you set up simple automated follow-ups right in the email editor – like sending a thank-you email when someone clicks a link or adding people to different email lists. The more expensive versions (Professional and Enterprise) let you create complex, multi-step email journeys that can branch in different directions based on what customers do on your website, how their status changes in your system, or signals from other tools you use. It also personalizes emails for each person, tests different versions, and shows you how well everything is working.
Who should use it: This works best for medium to large businesses where marketing, sales, and customer service teams all work together using the same system.
