Best AI email marketing tools: quick verdict

The best platform depends on the type of business you operate and the complexity of your email strategy.

Here are my recommendations based on the published features and current plans:

  • Brevo: Best overall for small businesses
  • MailerLite: Best for beginners and WordPress websites
  • Mailchimp: Best for familiar, guided email marketing

MailerLite is the easier alternative for bloggers and WordPress website owners who prioritise simplicity, forms, landing pages and newsletter automation.

Kit is particularly attractive to creators who want to grow and monetise a newsletter.

What is AI email marketing?

AI email marketing uses artificial intelligence to assist with creating, personalising, sending and improving email campaigns.

Traditional email-marketing software allows businesses to design emails, store contacts and schedule campaigns. An AI-powered platform can also help determine what to write, who should receive a message and when it should be sent.

AI email tools can help with:

  • Subject-line generation
  • Email copywriting
  • Content rewriting
  • Tone adjustment
  • Personalisation
  • Subscriber segmentation
  • Send-time optimisation
  • Automated sequences
  • Campaign analysis
  • Product recommendations
  • Lead scoring
  • Predictive behaviour
  • Translation
  • A/B testing ideas

AI does not guarantee that subscribers will open an email or purchase a product. Results still depend on list quality, trust, relevance, deliverability and the value of the offer.

What can AI email marketing tools automate?

What can AI email marketing tools automate?

A small business can automate several repetitive email tasks.

Welcome emails

A welcome email can be sent automatically when someone joins your list.

E-commerce businesses can remind customers about products left in their carts.

Re-engagement campaigns

Transactional messages

Some platforms can deliver receipts, confirmations, password-reset messages and account notifications.

Campaign optimisation

AI can assist with subject lines, tone, content variations and recommended sending times.

Best AI email marketing tool for WordPress

Best email marketing tools for wordpress

MailerLite is my leading recommendation for a new WordPress website.

It provides an official WordPress signup-form integration, landing pages, basic automation and a simple interface.

A basic WordPress email system could work like this:

  1. A visitor reads an article.
  2. The visitor joins the email list through a signup form.
  3. MailerLite sends a welcome email.
  4. The subscriber receives a helpful sequence.
  5. New articles are promoted through newsletters.
  6. Relevant products are introduced later.

Brevo is a strong alternative when the website needs:

  • Larger contact storage
  • Transactional email
  • SMS
  • Customer relationship management
  • More extensive business communication

Kit is the better choice when the WordPress website is built primarily around a creator, newsletter or digital products.

Best free AI email marketing tool

There is no single Free plan that wins every category.

Choose Brevo Free if:

  • You want generous contact storage
  • You send fewer than 300 emails daily
  • You need transactional messages
  • You may add SMS later
  • You operate a small business

Choose MailerLite Free if:

  • You are a beginner
  • You use WordPress
  • You have fewer than 250 subscribers
  • You need forms and landing pages
  • Basic automation is sufficient

Choose Kit’s Newsletter plan if:

  • You are a creator
  • You want to grow a large newsletter

  • You expect to build a sales pipeline

Best overall Free option for small businesses: Brevo
Best Free option for WordPress beginners: MailerLite

Best AI email marketing tool for creators

Kit is the best platform for creators.

It is specifically designed for people building an audience around their knowledge, personality or content.

Kit is suitable for:

  • Bloggers
  • YouTubers
  • Podcasters
  • Musicians
  • Coaches
  • Authors
  • Course creators
  • Newsletter publishers

The Creator Network, recommendations and monetisation features make it different from traditional business-focused email platforms.

MailerLite is a good alternative for creators who prioritise affordability and simple WordPress integration.

Best AI email marketing tool for automation

ActiveCampaign is the strongest option for sophisticated automation.

It is suitable when campaigns depend on several conditions and customer behaviours.

For example:

  1. A person downloads a guide.
  2. ActiveCampaign sends a welcome sequence.
  3. The person clicks a product link.
  4. The contact receives product-focused information.
  5. The person visits a pricing page.
  6. The lead is marked as more engaged.
  7. A sales follow-up is triggered.
  8. Unresponsive contacts enter a different sequence.

Brevo can provide more affordable automation for smaller businesses, while GetResponse is attractive for sales funnels and product launches.

How to choose an AI email marketing platform

Consider the following factors before registering.

Number of subscribers

Many platforms increase prices as your contact list grows.

A tool that costs little with 250 contacts may become expensive at 10,000 contacts.

Monthly sending requirements

Some tools limit:

  • Daily sends
  • Monthly sends
  • Emails per subscriber
  • Total campaigns
  • Automation activity

Calculate your expected sending volume before choosing a plan.

Business type

Different tools suit different users:

  • Creators: Kit
  • WordPress bloggers: MailerLite
  • Small businesses: Brevo
  • CRM-focused companies: HubSpot
  • Advanced marketers: ActiveCampaign
  • Funnel marketers: GetResponse
  • Familiar guided marketing: Mailchimp

Automation requirements

Do you need a single welcome email, or a complex journey containing several conditions?

Do not pay for advanced automation before your business needs it.

WordPress integration

Confirm that the platform supports your:

  • Signup forms
  • WordPress theme
  • Form plugin
  • WooCommerce store
  • Landing pages
  • Membership system

AI capabilities

Check whether AI is:

  • Included on Free
  • Restricted to paid plans
  • Controlled through credits
  • Limited to trials
  • Available only through an add-on

The presence of “AI” on a pricing page does not mean every user receives unlimited access.

Analytics

Useful metrics include:

  • Delivery rate
  • Open rate
  • Click rate
  • Unsubscribe rate
  • Bounce rate
  • Conversions
  • Revenue
  • Subscriber growth

Open-rate data can be affected by privacy features, so it should not be treated as the only measure of success.

Ease of use

A simpler platform is often better for a new business. Complicated automation provides no value if you never finish setting it up.

A new WordPress website should begin with a simple system.

Step 1: Create a valuable signup offer

Offer something useful, such as:

  • A checklist
  • A short guide
  • A template
  • A newsletter
  • Tool recommendations
  • Weekly updates

Do not ask people to subscribe without explaining what they will receive.

Step 2: Add a signup form

Place the form:

  • Within relevant articles
  • Near the end of articles
  • On the homepage
  • In the sidebar
  • On a dedicated landing page

Avoid placing so many popups that visitors cannot comfortably use the website.

Step 3: Send a welcome email

The welcome email should:

  • Confirm the subscription
  • Deliver the promised resource
  • Explain what emails will follow
  • Introduce the brand
  • Include one clear next step

Step 4: Create a short automated sequence

A basic sequence could contain:

  1. Welcome email
  2. Best article or resource
  3. Helpful lesson
  4. Tool recommendation
  5. Product introduction

Step 5: Send regular newsletters

Email subscribers when you publish genuinely useful content.

Step 6: Measure engagement

Monitor clicks, unsubscribes, replies and conversions.

Step 7: Improve the system

Remove ineffective emails, improve subject lines and refine your signup offer.

Do not build a twenty-email automation before confirming that people want the first five emails.

AI email marketing mistakes to avoid

Buying email lists

Never buy a list of email addresses. Recipients did not request your messages, and the practice can damage deliverability and violate privacy or anti-spam laws.

Adding people without permission

Use clear opt-in forms and maintain records of consent.

Sending AI output without reviewing it

AI can invent information or use an unsuitable tone. Review every campaign.

Misleading subject lines

A subject line should accurately represent the email.

Sending too many promotions

Provide useful information rather than turning every email into a sales message.

Ignoring mobile formatting

Test emails on mobile devices before sending.

Recipients must have a clear way to stop receiving messages.

Collecting unnecessary information

Only ask subscribers for information you genuinely need.

Ignoring deliverability

Maintain a healthy list by removing invalid addresses and monitoring bounced emails.

Overcomplicating automation

Start with a welcome sequence and one regular newsletter. Add complexity only when it serves a clear business purpose.
