AI email marketing: the tools, the prices and what the AI does

By Alexandre S. Published Last checked

AI email marketing means letting the tool suggest subject lines, draft the email, pick who gets it and choose the hour it lands. Of the 15 AI email marketing software tools on this page, 14 list AI features. The plan you pay for decides how much of it you get.

We read the pricing pages and terms of 15 email tools on 1 November 2026. Five say in their terms or policies that they may use your content or contacts to train AI. Two say they do not. One lets you opt out, and seven give no clear answer.

The plan matters as much as the tool. Mailchimp keeps generative AI off Essentials, so its cheapest plan that writes for you is Standard, from $20 a month.

Which email tool fits your job?

Pick what you send email for. Each job points to the pages that compare the tools built for it.

You write a newsletter

Platforms built for creators: paid subscriptions, a referral programme and a web archive.

You email prospects who never signed up

Cold email tools: sending mailboxes, warm-up, lead lists and AI replies.

You want the lowest bill for your list

What each tool costs at 500, 2,500, 10,000 and 50,000 contacts, side by side.

If none of the four fits, the list of AI email marketing tools sets all 15 side by side.

What AI in email marketing does, and on which plan

Email tools use AI for five main jobs. Each tool puts them on its own plans, so check the plan before the feature list.

Subject lines are the AI you most often get for free. Klaviyo lists its AI subject line generator on the free plan. Omnisend’s AI page says its free plan writes subject lines and preheaders too (Omnisend AI). GetResponse caps its subject line and email generators at three uses on Starter.

Generative AI that writes the email itself often sits on a dearer plan. MailerLite’s AI writing assistant starts on Comfort and is missing from Free. ActiveCampaign puts AI content generation on Plus, one plan above Starter. beehiiv gives its in-editor AI from Lite, its first paid plan. Pro adds more AI usage.

beehiiv's pricing page: Free at 0 dollars, Lite at 49 dollars a month and Pro at 95 dollars a month on yearly billing, with the beehiiv MCP on Lite and AI Credits marked High on Pro
beehiiv’s plan cards place its MCP connection on Lite and AI Credits on Pro beehiiv pricing page, captured

Segments are groups of contacts who share a trait, such as “bought twice, not opened in 60 days”. AI segment builders let you describe the group in a sentence. ActiveCampaign lists AI-suggested segments on all four plans, while Brevo keeps its AI segmentation for Professional.

Send time is when each email lands in each inbox. Brevo’s send time optimisation starts on Standard. MailerLite’s smart sending comes with Comfort, and Omnisend’s personalised sending time needs Pro or a paid add-on on Standard.

Brevo's pricing page, yearly billing: Starter at 8.08 dollars a month with an AI content generator and MCP for ChatGPT and Claude, Standard at 16.17 dollars adding AI send time optimization, Professional at 449.08 dollars adding AI segmentation and an AI Data Analyst, and Enterprise on custom pricing
Brevo’s plan cards put its AI content generator on Starter, send time optimisation on Standard and segmentation on Professional Brevo pricing page, captured

Product recommendations matter to online stores: the email shows each shopper items picked from what they browsed or bought. Omnisend sells them on Pro or as a Standard add-on. Brevo puts them on Professional, and GetResponse on Enterprise.

GetResponse's pricing page at 1,000 contacts: Starter at 15.58 dollars a month, Marketer at 48.38, Creator at 56.58 and Enterprise on custom pricing, each listing AI-powered content generators, with AI product recommendations listed under Enterprise only
GetResponse’s plan cards list AI-powered content generators on every plan and AI product recommendations on Enterprise GetResponse pricing page, captured

Several tools now also connect to ChatGPT or Claude through MCP. It is a link that lets an AI assistant read your account and build campaigns from a chat. Brevo lists it from Starter (Brevo pricing), Omnisend on every plan and MailerLite on Free, in a limited form.

MailerLite's pricing page at 500 subscribers: Power at 22.50 dollars a month billed yearly, Comfort at 10.80 dollars, Free at 0 dollars with 250 subscribers and an MCP connection for Claude and ChatGPT, and Enterprise on custom pricing, with HeyLite intelligence listed on Power, Comfort and Enterprise

Which AI feature sits on which plan covers all 15 tools feature by feature.

What each tool costs at your list size

Nine of the 15 tools charge by the size of your list. A price at 1,000 contacts tells you little about the bill at 10,000.

Kit’s free plan covers up to 10,000 subscribers, by Kit’s help centre, and Substack’s free newsletter charges no fee by list size. At 10,000 contacts, HubSpot’s Starter plan is the dearest of the published prices.

Each vendor counts a contact its own way. Mailchimp counts unsubscribed contacts, and Brevo bills by emails sent. The email marketing price data adds the 2,500 and 50,000 contact prices and explains each rule. Its finder gives the cheapest plan for the list you type in.

Does your email tool train AI on your list?

Five of the 15 tools give themselves the right in their terms or policies. They are ActiveCampaign, Apollo.io, Brevo, Mailchimp and MailerLite. Mailchimp’s section 30 grants it an irrevocable licence to your AI inputs and outputs for developing its AI model (Mailchimp terms).

HubSpot may train its AI models on your data unless you opt out in your account settings (Customer Terms 5.3.1, dated 16 September 2026). GetResponse says the AI models it picked do not learn from your content (terms section 10, dated 9 June 2026).

Kit’s help centre says Kit trains no AI on Kit data. The terms of beehiiv, lemlist, Omnisend, Smartlead and Substack say nothing either way. Klaviyo’s clause 8.1 bars training third-party foundation models without mentioning its own, and Instantly’s clause 4.3 covers only how third-party model providers handle your inputs.

That matters when your list holds customer data you promised to protect. Does your email tool train AI? quotes each clause with its date and opt-out.

How to use AI for email marketing without wasting a plan

Start with the AI you already pay for. Klaviyo and MailerLite put subject lines on a cheaper plan than full drafts, so test that first.

  1. Test the AI subject line against your own. Kit’s free plan includes A/B testing of broadcasts for up to 10,000 subscribers (Kit free plan), so the test costs nothing there.
  2. Let AI draft, then rewrite the opening. Rewrite the opening in your own words, and check every claim and price the draft makes before it goes out.
  3. Build one AI segment you can check by hand. Describe it in a sentence, then open the list and see who landed in it.
  4. Upgrade for send time last. Brevo puts it on Standard and Omnisend on Pro or a paid Standard add-on, so pay for it after subject lines and drafts are working.

Cold email to people who never signed up works differently: AI cold email tools covers Instantly, lemlist, Smartlead and Apollo.io.
