AI Email Marketing Tools: What the Platforms Actually Include

The AI email marketing tools most businesses will use are the ones already inside their email platform: writing assistants that draft copy and subject lines, image generators, and — on some plans — tools that choose send times or suggest segments. Most of the platforms we compare list at least one of these, and what separates them is which kind, and on which plan.

This page lists what each vendor's pricing or features page said about AI on 22 September 2026. We have not measured whether any of these features improves results, and no vendor publishes figures that would let anyone check; we describe what is offered, not what it achieves.

The four kinds of AI in email platforms

The AI features on offer fall into four groups, and it helps to know which you are buying before comparing plans. Writing help is the kind most vendors list; data features are listed by fewer of them.

• Writing: drafting email copy, rewriting for tone or length, fixing grammar, suggesting subject lines.
• Images and pages: generating images for emails, or building landing pages and signup forms from a prompt.
• Timing and targeting: choosing a send time per contact, suggesting segments, recommending products.
• Access for outside AI tools: connections that let an AI assistant you already use work with your account.

What each platform lists

Here is what each vendor's own pages named on the day we checked. The wording is theirs; we have grouped it.

• GetResponse: "AI-powered content generators" on every plan, from Starter up, plus AI tools for landing pages, a website builder and product recommendations in its product menu.
• Brevo: an AI content generator for subject lines and email copy, including tone; AI send-time optimisation; AI segmentation and an "AI Data Analyst" that answers plain-language questions about your data (branded Aura AI). Brevo's plan comparison sets out which tier includes each.
• AWeber: an AI subject-line assistant and an AI writing assistant, with AI builders for landing pages and signup forms in its product menu.
• Moosend: an "AI Writer" included in its trial feature list, and AI-driven product recommendations.
• Benchmark: "Smart Text" to refine tone, expand, summarise and correct copy, and AI-generated images in the email editor.
• Mailchimp: generative AI features listed at no additional cost on its Standard and Premium plans and not included on Essentials. Mailchimp pays us nothing.
• MailerLite: an AI writing assistant on its Comfort plan, and access for outside AI assistants (via MCP) listed from the free plan up. We compare it, but do not review or link it.

Sender's and EmailOctopus's pricing pages did not list AI features when we read them; that says nothing either way about their products, only about their pricing pages.

Writing assistants: useful, with a check

AI writing tools are most useful for the parts of an email that are hard to start: a first draft, three alternative subject lines, a shorter version of a long paragraph. Most platforms now list one, so it should not decide your choice on its own.

Treat every AI draft as a draft. It does not know your prices, your stock or your returns policy unless you tell it, and it will write confidently about all three. Read every figure, date and promise before sending. That matters legally as well as commercially: the FTC's CAN-SPAM guidance bans deceptive subject lines whoever — or whatever — wrote them.

Send times, segments and recommendations

Timing and targeting features are where AI touches your data rather than your words. Brevo lists send-time optimisation, which picks a send time per contact from past engagement, and AI segmentation that suggests audience groups; GetResponse and Moosend list AI product recommendations.

These features need history to work from, so they do little for a new or small list. A business with a few hundred subscribers and a handful of past campaigns will learn more from reading its own click reports. Once you have a year of campaigns and purchases, they become worth testing — by sending half a campaign each way and comparing the results yourself.

Connecting outside AI assistants

A newer kind of AI feature lets an assistant you already use — a chat assistant on your computer, for example — work with your email account directly. MailerLite lists this access (via MCP, the Model Context Protocol) on every plan including the free one, and MailerSend lists an MCP server for its sending API.

This can save time on routine work such as pulling a report or drafting a campaign in your account. It also means an outside tool can act in your account, so give it the narrowest access that does the job, and keep a person approving anything that sends.

Which plan the AI is on

The plan matters as much as the platform. Mailchimp's generative AI is not on Essentials; MailerLite's writing assistant is listed on Comfort, not Free; Brevo's plan comparison is the place to check which tier carries its data features. GetResponse lists its content generators on every plan, starting with Starter at $19 a month for 1,000 contacts on monthly billing.

If AI writing is the feature you want, check it is on the entry plan — on Mailchimp it is not. If you want AI working on your data — send times, segments, analysis — read the plan comparison carefully, because those features are not always on the cheapest tier.

What AI cannot fix

No AI feature changes the basics that decide whether your email arrives and is welcome. Google's published sender guidelines still require SPF or DKIM from every sender to Gmail accounts, and SPF, DKIM, DMARC and one-click unsubscribe from senders of more than 5,000 messages a day, with the spam rate kept below 0.3%.

A list of people who asked to hear from you, emails that say something useful, and a working unsubscribe matter more than any generated subject line. Our guide to bulk email services covers the setup; our ranking of the best email marketing software weighs AI features as one small part of a platform, not the reason to choose it.

A simple way to test an AI feature

You can judge an AI feature on your own list without trusting anyone's figures, including ours. The method is the same split test marketers have always used.

1. Pick one feature to test — AI subject lines, say — and one campaign you would send anyway.
2. Split the list at random into two halves of equal size.
3. Send one half your usual version and the other the AI version, at the same time.
4. Compare clicks and replies, not only opens, a day or two later.
5. Repeat over several campaigns before deciding; one send proves little.

Keep the test honest by changing only one thing at a time. If the AI version wins consistently, keep it; if it does not, you have saved yourself the upgrade.

Choosing with AI in mind

Choose the platform on price at your list size, sending model and automation first, then check that the AI features you want are on the plan you would buy. For most small businesses, a writing assistant on the entry plan is enough: GetResponse lists its content generators on every plan, and Benchmark says every feature, Smart Text included, is on both of its plans.
