The buyer question · Updated Jun 16
Best Email Marketing Software
We put this question to ChatGPT, Claude, Gemini and Perplexity every week — then check their pick against the people who actually used it.
Power ranking
The top products right now.
This week?
Marketing Hub Professional jumped seven spots to claim the top rank for email marketing software. Mailchimp Standard and Marketing Automation Platform both entered the top four this week, forcing a reshuffling among established names. SendinBlue Email Marketing fell hard, dropping twelve places to twenty-eight. The movement suggests AI assistants now weight different criteria when they rank email tools—performance gains and new entrants are pushing older fixtures down the list.
What AI values here
The AI consensus centers on automation and templates as the core strengths that separate top picks—so prioritize how well a platform can run campaigns on its own and handle the design work for you. Segmentation capability matters next, since it determines whether you can actually target the right people with those automated messages.

The verdict

They agree, we say so. They split, we show you the gap.
Act one
What the machines think.
Three AI models read the category and rank every product. They agree on the very top — and split harder than anywhere else below it.
Model by model?
How each AI ranked it.
All three models open with the same #1 when they agree — below it their lists diverge. Each column is one model's own ranked picks; the lead pick sits a touch larger, and a lone tag marks a product only one model chose. The board below merges them into one machines-only top 10.

What matters most when choosing an email marketing tool?
Automation and segmentation are the core functions that separate the leading tools—these let campaigns run on their own and reach the right people. Ease of use, templates, and CRM integration are supporting features that make those core functions actually usable.
What if I need landing pages alongside email?
GetResponse's Marketing Automation Platform and MailerLite Advanced both include landing pages along with email automation. ConvertKit's Kit Creator Pro also offers landing pages and is built for creators.

Beyond this question
Where the winner shows up elsewhere.
context & history
Most teams want a tool that sends email without breaking the budget or the workflow. You need something that works with what you already use. You need to know if it scales when you grow.
The market splits three ways. Mailchimp and Klaviyo handle automation well but cost differently at scale. HubSpot bundles email into a larger platform, which saves money if you use the rest. Brevo and Sendinblue compete on price. What matters is whether the tool talks to your CRM, how many contacts you can reach for the money, and if the reporting tells you what actually worked.
